Problems solved by technology

[0002] At present, the well-known existing domestic and foreign hybrid electric vehicles, whether they are series, parallel or hybrid, all use one engine. Because the demand for power changes greatly during the driving process of the vehicle, it is difficult for one engine to take care of both. Fuel economy, power and emissions have brought many difficulties and problems to energy saving, vehicle driving power selection, safety, environmental protection, etc.

Its advantages are simple structure, saving oil, and low environmental pollution and cost.

Description

technical field [0001] The invention belongs to the class of motor vehicles, in particular to hybrid vehicles. Background technique [0002] At present, the well-known existing domestic and foreign hybrid electric vehicles, whether they are series, parallel or hybrid, all use one engine. Because the demand for power changes greatly during the driving process of the vehicle, it is difficult for one engine to take care of both. Fuel economy, power and emissions have brought many difficulties and problems to energy saving, vehicle power selection, safety, and environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a dual-engine series hybrid electric vehicle to solve the above-mentioned problems, so as to meet the needs of improving driving power, increasing power, saving fuel and exhaust emissions. [0004] The purpose of the present invention is ach...
