1. The coin win alliance can take you to do it, and the blockchain is not very difficult. With the great God of the coin win alliance, you are not afraid that there are no good projects to do.

2. The blockchain that can do better now is the coin win alliance. There are many other pitfalls. You really need to be careful. The coin win alliance project can be better and make money.

3. Unknown_Error

4. There's no best. It's almost the same. Cummins, DEUTZ, man, Isuzu, Mitsubishi, Kubota, Yangma
among them, Yangma diesel engine is the most used small excavator, which is characterized by fuel saving. Kubota's small engine is the world's biggest seller.

5. You have to find the kind of good projects to do, or go in vain, coin win alliance can be considered, more God, strong technology, good project.

6. Mitsubishi DEUTZ uses Yangma and Mitsubishi engines the most in small digs, while Isuzu Cummins uses more in large digs,

7. Which model are you asking? Yuchai 85-8 uses Cummins and Yuchai engines, Toshiba and KYB hydraulic systems, and Shantui chassis

8. The excavator is not expensive on the engine. It has only one engine, which is not much different from the truck engine. However, because the working environment of the excavator is worse than that of the truck, the engine requirements are higher than that of the truck.
the expensive aspect of the excavator mainly focuses on its hydraulic system, Among them, the main pump (converting the rotary kinetic energy of the engine into high-pressure hydraulic energy), the main valve (distributing the hydraulic energy output by the main pump to each working device), the hydraulic cylinder (converting the hydraulic energy into reciprocating kinetic energy), the hydraulic motor (converting the hydraulic energy into rotary kinetic energy)
in addition, the chassis and cab of the excavator are also quite expensive
besides the engine, the truck only has a steel body, so it is cheaper

9. Everything has a process of development. At present, domestic enterprises are at a stage of development in terms of independent intellectual property rights and independent research and development. And most of them are still imitating or, worse, plagiarizing. Construction machinery engine performance requirements, domestic engine is really difficult to be as rable as imported goods. To tell you the truth, if you can use domestic ones, who will use imported ones? The transformation from made in China to R & D in China needs a process, which should be completed within 100 years of the primary stage of socialism. The transformation from a traditional agricultural power to an instrial power has not yet been successful. We still need to work hard
besides, nowadays ecation is paying more and more attention to innovation, but there is still a certain distance, which is also the premise of independent research and development
another important factor is that when we choose our own equipment, we should also support domestic procts. We always think that imported procts are good, and we are not willing to give opportunities to foreign enterprises. When we say imported procts are expensive, we should always consider domestic procts. Anything can be improved only when its weakness is fully exposed in use, and our domestic procts have a gap in this point
in a word, one day, our technology will stand in the east of the world like our nation!

10. The imported vehicle is generally Isuzu 6102 turbocharged intercooled diesel engine.
