[0002] The front wheel system of a traditional diesel engine is equipped with a mechanical air conditioner and a generator, which respectively provide cooling for the cab and power for the low-voltage battery. For hybrid vehicles, there is no need to configure a mechanical air conditioner on the engine, and the cab cooling is achieved by configuring a high-voltage electric air conditioner on the vehicle; there is no generator on the engine, and the low-voltage battery draws power from the power battery. Therefore, the front wheel system of a hybrid-specific engine needs to be redesigned.

[0003] If too many wheels are used in the design, this will have a significant negative impact on the overall layout design and lightweight of the entire engine. Utility Model Content
