1, the use of diesel engines. The start-up frequently and often moving machinery, such as tractors, agricultural vehicles, such as mobile power station can use high-speed diesel light; fixed for the power plant, such as agricultural irrigation and drainage, the motive power of agricultural and sideline products processing machinery, they can choose to use a lower speed and the potential for more The big diesel engine.

4, as part of the natural wear and tear and other factors, long-term operation of the diesel engine in the kind of power and economy will be gradually reduced, so the package when the diesel engine power due to leave room in order to give full play to its effectiveness. Should also be considered at high altitude above sea level due to high power caused by low air pressure drop.
