There are ten generations by 2019
The first generation Accord was developed in 1976-1980 to deal with the energy crisis and explore the harmony between people and vehicles. The car is designed with low fuel consumption as its original intention, and comes out with wide interior space, excellent driving performance and novel hatchback image In the power part of 2018 Honda Accord, the domestic accord is currently equipped with 1.5T engine, high-power version of 260turbo model, with maximum power of 195 HP (143 kW) / 5500rpm and maximum torque of 260 nm / 1600-5000rpm; The low-power version of 230 turbo has a maximum power of 177 HP (130 kW) / 6000 rpm and a maximum torque of 230 nm / 1500-3000 rpm. In terms of transmission, CVT gearbox is matched with it2. Hidden causes and solutions of increased fuel consumption:
tire
low tire pressure will increase the contact area between tire and ground, which will not only increase fuel consumption, but also cause damage to tire wall, and there will be hidden danger of tire burst when driving at high speed, so it is necessary to keep reasonable tire pressure at ordinary times. Excessive tire wear can also lead to tire slippage and loss of kinetic energy. In addition, the wide tire is modified to increase the friction between the tire and the ground
the tire pressure is not balanced, the friction and lateral steering resistance also increase correspondingly, and there are also potential problems such as deviation, steering difficulty and poor braking effect. There are three types of tread patterns: one is cross-country; the other is cross-country; One is athletic; One is comfortable and quiet. The off-road tire has a large tread pattern, which is suitable for driving in bad road conditions such as sand and gravel. It consumes the most fuel. Sports performance tires generally emphasize grip, wide tread, easy handling and medium fuel consumption. Comfortable, quiet tire because of its fine pattern, smooth, so the lowest fuel consumption
carbon deposition on spark plug
If carbon deposition on spark plug increases or the spark plug is aged, the ignition energy and ignition stability will decrease, and the fuel consumption will increase. It is suggested that users of urban (reference, picture, inquiry) cars should clean every 20000-30000 km, and replace the spark plug regularly according to the different material
air intake system cleaning
the cleanliness of the car is directly related to the working condition of the engine, thus affecting the fuel consumption. We should pay special attention to the air filter and throttle. In general, it is recommended to replace the air filter every 10000 km in the north and 15000 km in the south. If conditions permit, the air filter can be reversed by compressed air at 5000 km. Throttle experts recommend cleaning every 20000-30000 km. The air flow meter also affects the fuel consumption. Its accuracy is related to the accuracy of the air-fuel ratio of the engine. If there is a problem, it is bound to increase the fuel consumption. If the flow meter is damaged, it must be replaced
replacement of mechanical filter and steam filter
many car owners will ignore the regular replacement of mechanical filter and steam filter. Many car owners can also guarantee to replace the mechanical filter when changing the engine oil, but the steam filter is ignored by many car owners. When the steam filter is dirty, it will provide the wrong signal to the control unit, resulting in increased fuel consumption. It is recommended to replace the two filters regularly
four wheel alignment
if the vehicle's four wheel alignment is not good (the toe angle and inclination angle are not correct), the friction between the tire and the ground will increase, which will not only damage the tire itself, but also increase the fuel consumption
brake
brake system or axle failure affects wheel rotation and increases fuel consumption
driving for a short distance
in practice, it takes quite a long time for the engine of a cold car to reach the best condition of its components. Generally speaking, the distance is - 4km
the temperature control switch and thermostat are damaged
this situation makes the water temperature lower and the carburetor can not work normally, resulting in poor atomization of gasoline and increasing fuel consumption< When the temperature is low in winter, manual transmission is recommended for about 1 minute and automatic transmission is recommended for about 2 minutes. Before the water temperature reaches normal, it is recommended to control the speed below 50 km / h. In the morning, the hot car is not just waiting for the speed of the car to drop to the normal value or the water temperature to rise to the normal value, which is just like having trouble with your wallet
nozzle cleaning
because whether the fuel atomization is good or not, it will directly affect the combustion of the engine, resulting in increased fuel consumption, so experts recommend cleaning the nozzle every 60000 km or so
engine water temperature
the normal engine water temperature should be kept between 80 ℃ and 90 ℃, too high or insufficient will increase fuel consumption. In particular, if the water in the water tank is insufficient, it is easy to cause the water temperature to rise rapidly. When the water temperature exceeds 95 ℃, the fuel consumption will increase by 30% - 40% compared with the normal temperature, and it is easy to cause wear and damage to the parts
too much or too little lubricating oil
if there is too much lubricating oil, the engine oil will participate in the combustion, resulting in incomplete combustion of the mixture, carbon deposition in the spark plug, muffler and other parts, increasing fuel consumption, slow growth rate and power decline; If the lubricating oil is too little, it will cause the dry friction between the matching parts, which will overheat the engine, rece the power and increase the fuel consumption
the "three filters" have not been replaced for a long time
in the process of vehicle use, the three filters (oil filter, air filter and gasoline filter) must be replaced regularly. If they are not replaced for a long time, they will become dirty and greasy, affect the use, and send error messages to the engine control unit, resulting in insufficient fuel combustion and increased engine carbon deposition
oxygen sensor
as an internal control unit, if the oxygen sensor is damaged, the fuel gas mixture ratio will also be affected, thus increasing fuel consumption
the water temperature sensor is out of alignment
once the signal of the water temperature sensor is out of alignment or the circuit of the electronic fan is abnormal, the electronic fan will run continuously. At this time, the water temperature of the engine will drop and the fuel consumption will increase if the water temperature of the engine is too low
insufficient cylinder pressure
it is generally e to poor air tightness of the cylinder (which is usually found in cars that have traveled 200-300 thousand km), resulting in the rection of energy conversion efficiency of the engine and the increase of energy consumption< At the same speed, the difference in fuel consumption can reach 12 ml, and 0.4 g of carbon monoxide will be emitted per kilometer. In addition, rapid acceleration causes strong friction between the tire and the ground, accelerating tire wear. It is also easy to cause carbon deposition in the engine
unnecessary high-speed driving
any car has its own economic speed, which is the most fuel-efficient when driving at this speed. If the speed is lower than or higher than this speed, the fuel consumption will rise, and if the speed is higher than a certain speed, the fuel consumption will rise greatly. Generally at 70 ~ 90, the higher the speed is, the greater the wind resistance will be, and the car body will start to float, which will also affect the safety
other
engines have too much carbon in them, and high-speed window opening also costs more fuel. Frequent braking, too much load increase the weight of the vehicle, the fuel tank full makes the car load increase, increase fuel consumption. When idling for a long time, if the engine doesn't stop or ignites frequently, if the air conditioner is turned on for a long time, the fuel consumption will also increase.

I have driven both CR-V and accord, and I have a say in these two cars
CR-V is the standard of 2012 model, with 2.0 displacement. 9 generation Accord 2.0 top configuration
from the driving point of view: the accord is more comfortable, especially smooth when driving at high speed, CR-V just looks a little bigger, the chassis height is average, I feel a little floating at high speed 120, of course, my driving skills are average
the CR-V of the 2012 model is an at transmission, while the 9ya is a CVT. There is still a difference in this point. The 9ya transmission is still not so bold to step on
CR-V is better than 9ya, and all kinds of details are better than 9ya. There is basically no abnormal sound. When my 9ya just came back, there was an abnormal sound. When it's cold in winter, the horn doesn't sound on the side, so I need to press the middle position
4. Honda CR-V has been localized since 2004 and has been deeply rooted in the Chinese market. Over the years, it has gained high popularity and high sales volume in China. Consumers who pay attention to this level will naturally understand another SUV: Nissan Qijun. But when it comes to Nissan Qijun, it gives people the feeling that the words come to their lips, but they can't say anything. Yes, we know that Qijun has been selling very well in the past two years, but how can it leave such a weak impression on everyone when it has been in the market for nearly 20 years? In this case, if you look around the history of Honda CR-V and Nissan Qijun, you will find that their relationship is so far and so close..
when CR-V was booming, Qijun was still on the design draft
as the big brother of SUV market, the first generation of Honda CR-V was launched in Japan in 1996, which was Honda's first self-designed compact SUV, There is also an SUV Honda passport developed in cooperation with Isuzu. Because Honda didn't incline to CR-V too much in the channel, the proct didn't get the attention of Japanese market in the initial stage. It was not until its first exhibition in the United States in 1996 that it gained market attention<
in February 1997, Honda CRV was officially listed in the U.S. market, and soon surpassed Toyota RAV4, which was very popular at that time. The next year, Honda CRV became the sales champion of compact SUV in the U.S. market, with annual total sales exceeding 100000. Honda CR-V, which is popular in the United States, soon brought its popularity back to Japan, and Japanese consumers really began to pay attention to this model. In 2000, Honda CR-V became the best-selling SUV in Japan, surpassing the then champion Toyota Land ruiser for the first time<
Nissan, one of the three largest auto manufacturers in Japan, saw the great success of Toyota RAV4 and Honda CR-V in the U.S. market, and finally launched the first compact SUV: X-Trail in September 2000, and officially sold it in November of the same year
the first generation of Nissan X-Trail well absorbed the aesthetic of SUV in the U.S. market. The overall design is the same as that of Honda CR-V at that time. It has a strong off-road style, and its power and torque adjustment is comparable to that of Honda CR-V in the medium term. But after all, the launch time of the proct lags far behind the development of the whole market, the proct itself has not enough bright spots, and the expansion of sales channels outside Shanghai is several years later than that of domestic market. Therefore, the first generation of Nissan X-Trail seems to be more to fill the vacancy in compact SUV, commonly known as "zhankeng"< However, the launch of Nissan X-Trail in Japan coincides with the end of the first generation of Honda CR-V procts, which gives Nissan X-Trail a chance to sneak attack and its sales in Japan quickly surpass that of Honda CR-V< In 2002, Honda launched the second generation of CR-V. the proct design changed the image of the previous generation of tough guy, added more smooth lines, and became more sporty and fashionable. The proct image of off-road vehicle graally moved closer to the positioning of urban SUV. This kind of strategy adjustment can be said to be a magic stroke in the market at that time, because the proct design at home and abroad was still based on the style of off-road vehicles, which made the second generation Honda CR-V unique. In addition, the powertrain and other configurations of the second generation procts are improved compared with those of the previous generation, which has helped its global sales rapidly exceed 2 million units.

5. The fuel consumption suddenly becomes high. You need to check the spark plug and throttle.
6. Toyota, Honda, Audi, BMW no matter what car, burning oil is abnormal< A few days ago, there was a BMW 5-series car with serious engine oil burn. It was necessary to add a bucket of engine oil after 1000 km. Later, a friend introced using super eutectic engine oil. As a result, half a month later, there was no need to add any engine oil at all. And his excavators and big diesel cars don't burn oil
and the Audi cars of Puyang Land Bureau all burn engine oil. Someone gave them super eutectic engine oil, but they didn't burn any more. The leaders were very satisfied
it is recommended that when you change the engine oil, use the internal cleaning agent of Hypereutectic engine, and then change the hypereutectic engine oil
if you feel that the power is insufficient, add a few bottles of Hypereutectic fuel oil
if the wear is large, add super eutectic engine strong anti-wear repair agent

7. If you like fashionable styling, you need to occasionally take a self driving tour. The driving environment is rather harsh, or you need to take a small cross-country trip on weekends, Mitsubishi Outlander will be a better choice. Because the new outlander, no matter the chassis tuning or cross-country equipment, is the best in the current medium-sized SUV. Mitsubishi's old line is playing cross-country, There is no doubt about this.
Honda CR-V is a multi-function car, which is basically based on the car chassis. The walking system is very soft and comfortable. The engine is also very fuel-efficient. With its flexible and spacious interior space, it is more like an ideal family car, suitable for walking and stopping in the city.
in terms of brand, Honda's reputation in China is obviously better than Mitsubishi's. However, the new outlander is imported with the original vehicle, but the price is similar to that of the domestic CR-V. being a trade union is more rigorous than that of the domestic CR-V, which depends on whether you want the brand or the cost performance.
finally, Dongfeng Honda has 4S stores all over the country, which is very convenient for maintenance, The price of domestic parts is also relatively reasonable. Mitsubishi still shares 4S stores with Beijing Daike. There are not many 4S stores and few outlets. There are small problems in the maintenance cost of imported parts and the maintenance technology of 4S stores.
overall, CR-V is more suitable. It's just a suggestion. The key depends on which one you pay attention to

8. Hidden causes and solutions of increased fuel consumption:
tire
low tire pressure will increase the contact area between tire and ground, which will not only increase fuel consumption, but also cause damage to tire wall, and there will be hidden danger of tire burst when driving at high speed, so it is necessary to keep reasonable tire pressure at ordinary times. Excessive tire wear can also lead to tire slippage and loss of kinetic energy. In addition, the wide tire is modified to increase the friction between the tire and the ground
the tire pressure is not balanced, the friction and lateral steering resistance also increase correspondingly, and there are also potential problems such as deviation, steering difficulty and poor braking effect. There are three types of tread patterns: one is cross-country; the other is cross-country; One is athletic; One is comfortable and quiet. The off-road tire has a large tread pattern, which is suitable for driving in bad road conditions such as sand and gravel. It consumes the most fuel. Sports performance tires generally emphasize grip, wide tread, easy handling and medium fuel consumption. Comfortable, quiet tire because of its fine pattern, smooth, so the lowest fuel consumption

this situation makes the water temperature lower and the carburetor can not work normally, resulting in poor atomization of gasoline and increasing fuel consumption< When the temperature is low in winter, manual transmission is recommended for about 1 minute and automatic transmission is recommended for about 2 minutes. Before the water temperature reaches normal, it is recommended to control the speed below 50 km / h. The hot car in the morning is not just waiting for the vehicle speed to drop to the normal value. I hope it can help you!

9. First of all, let's correct the misunderstanding of several friends downstairs about the CRV four-wheel drive system. CRV has been using the DPS (al pump system) four-wheel drive system developed by Honda itself. Its working principle is actually the same as that of the electronically controlled multi disc clutch, which uses the pressure of hydraulic oil to compress the clutch plates to achieve the purpose of transmission power, The difference is that the DPS system of CRV before the 12 models is a purely mechanical passive actuation system, which uses the speed difference between the front and rear wheels to make the pump wheel of the hydraulic pump rotate, and provides the pressure to compress the clutch plate through the hydraulic oil, while the electronically controlled multi plate clutch is equivalent to the active (electronically controlled) control of the hydraulic pump, which provides the pressure to compress the clutch plate through the hydraulic oil! The 13 four-wheel drive CRVs upgrade the four-wheel drive system, equipped with the e-dps system used in Acura RDX. In fact, the upgrade is also very simple, that is, replacing one of the two pumps with an electric pump (motor driven), changing passive control into active control! Of course, you should not expect these SUVs below 50 to have any good off-road performance. The two or three hundred thousand urban SUVs will not focus on off-road performance. In fact, the four-wheel drive system they are equipped with has almost the same performance. They all improve the controllability when there is a limit state on the road!! In addition, since the last generation of CRV, there has never been any four-wheel drive system such as viscous coupling. He has been using DPS al pump four-wheel drive system. You know, don't spread the wrong information
in addition to the Subaru foresters, many foresters who belittle CRV take the viscous coupling of CRV as an example. Unfortunately, the viscous coupling is equipped by 2.0 displacement foresters. Many people think that the viscous coupling is a fake 4WD. In fact, it's not. Even Mitsubishi's off-road vehicles use viscous coupling, Whether the off-road performance of the four-wheel drive system is good or not depends on the manufacturer's positioning of a vehicle. It doesn't mean that as long as a four-wheel drive vehicle has off-road ability, it needs to have strong off-road ability. It doesn't make sense to have four-wheel drive alone. It also depends on whether it has some auxiliary devices to get rid of difficulties, For example, the differential lock (you can see in the video that the off-road ability of the two drive pickup equipped with Eaton differential lock is much higher than that of the ordinary full-time four-wheel drive vehicle), in addition to some mechanical devices, it also has four-wheel electronic auxiliary system (such as the Middle East version of the Land Cruiser), and it also depends on whether it has a transfer box with torque amplification ability (necessary for hard off-road, such as the herdsman, overbearing, etc.), Whether they have off-road tires (the most important factor) and the off-road skills of drivers (the more important factor) - therefore, in the current situation of equal technical strength of various manufacturers in the automotive instry, what kind of performance a car has is determined by the manufacturer's vehicle positioning
there are many misunderstandings about Subaru's horizontally opposed engine. Horizontally opposed engine is not advanced compared with in-line four cylinder engine, and it even lags behind from the time of its birth. H-type horizontal engine was first used in piston engine aircraft, but it was soon eliminated, The reason for the elimination should be known to those who have studied the principle of piston engine, that is, although horizontally opposed engine has the advantages of small vibration and slightly stronger output torque at the same displacement, its disadvantages are also very obvious --- very inconvenient maintenance, uneven wear (e to gravity), excessive oil consumption and so on, When the negative impact of a technology's shortcomings exceeds the positive impact of its advantages, it will be eliminated! Subaru is one of the few manufacturers that insist on developing this technology. Through continuous efforts and technological development, Subaru strives to enlarge the advantages of horizontally opposed engines and minimize the negative impact of its disadvantages. In the instry, manufacturers without unique technology will not survive, while in Japan, such as Subaru (only refers to Subaru's automobile parts, Fuji Heavy Instry's aviation technology is second to none in Japan). The reason why small manufacturers such as Mazda can survive among the three major Japanese brands is inseparable from their unique technology (such as horizontal opposed, Mazda's rotor engine)
different people have different opinions about the choice of Forester and CRV. The characteristics of the two cars are different, so which one is suitable for your own purpose is the best one
CRV: made by Honda, quality assurance --- there is no doubt that the high reliability of Honda's engine, gearbox and various parts is well-known (even Toyota and Nissan are willing to take the lead in this point, and a lot of European cars with low reliability are going to have fun)
excellent workmanship - CRV interior materials are not very good, But it doesn't affect its assembly process and workmanship
big space --- Honda's optimization technology level of interior space has always been considered the first in the instry. You can go to CRV and civic space by yourself
low cost of use - maintenance, insurance and repair are much cheaper than forest people
advanced i-vtec engine - don't use the i-vtec logo on the back of Honda car as a dish. This is one of Honda's housekeeping technologies (the other is sh-awd of course). Of course, VTEC is intended to be used to equip high-performance engines on high-performance vehicles, However, it has become a pronoun of high reliability and low energy consumption --- Honda engine technology has its own disadvantages: 1. Although Honda has never publicized CRV as a SUV with strong off-road ability, it has become a vehicle with high reliability and low energy consumption, People's original intention of designing CRV is a family station wagon with high reliability, high quality and large space. However, since most people criticize CRV, let's consider it a disadvantage! 2. The materials used for interior decoration are too cheap. It's not cheap for a 250, 600 thousand car. It's really wrong to use so many hard plastics! 3. The suspension is loose, and the curve roll is large. 4. The ground clearance is not higher than that of the car, which leads to the rection of trafficability. 5. Due to the good reputation, it turns into a streetcar and has no personality
Forester: with Subaru's reputation in the event, Subaru's civil cars naturally become synonymous with performance! The 13 models of foresters have good trafficability (only for 2.5 and 2.0 XT models), rich driving modes (such as X-mode), and actually perform very well. With more than 200 ground clearance, CRV can only give foresters a deep glance in front of many road conditions; Fairly good quality; In the same class of cars, the handling feeling is quite good, and the climbing ability is one of the most popular reasons for Subaru! After being told by Toyota, the workmanship is improved again! Compared with CRV, it gives people a firmer and calmer chassis (in fact, this feeling is inseparable from all-time four-wheel drive. Although the chassis of CRV is not much loose, CRV mostly has two drives. Two drives drive the long body, high body and heavy body, which is the light and loose feeling)< Disadvantages: in fact, I don't need to look at the car dismantling workshop. I have dismantled these two kinds of cars myself. It can be said that after removing the decorative materials, the assembly technology of the two cars has reached the level of the large and small factories! Compared with CRV's intention to build a car (for example, the meticulous standardized wiring and line protection), Subaru's wiring is like the work of a small workshop. I feel that the handling of many places is very tricky! A domestic expert said that if the forest people are made in China, they will be a car of more than 100000. Although I don't agree with that, the craft is really similar!! It's inconvenient to repair, the maintenance is relatively expensive (imported car, there's no way)
I'm tired after writing so much, I just want to tell you that these two models are good, mainly to see which one is more suitable for you 15:50 PM, August 25, 2013 (original)
