Description

technical field [0001] The invention designs an APU device driven by a diesel engine, which belongs to the auxiliary power system of the automobile. Background technique [0002] In traditional electric vehicles, the power diesel engine, generator, heat dissipation system, intake system, and exhaust system are designed separately, and then form a set of power assemblies for electric vehicles, but the layout of each system is not compact. The structure is generally unfavorable for installation and maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a diesel-driven APU device for the problem that the structure of the existing diesel-driven APU system is not compact. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: the APU device driven by the diesel engine includes an APU shelter, a diesel engine, a generator, an intake filter and an exhaust device...
