Horizontally-opposed balance type gasoline range extender and operation method thereof

Abstract

The invention discloses a horizontally-opposed balance type gasoline range extender and an operation method thereof. The range extender comprises a horizontally-opposed piston two-stroke gasoline engine, a transmission case and an electric generator. The power output end of the horizontally-opposed piston two-stroke gasoline engine is connected with the transmission case, and an output port of the transmission case is connected with a rotor shaft of the electric generator. By means of the technical scheme, the defects that a traditional two-stroke gasoline engine is poor in economy and emission performance and the like are effectively overcome, the advantages of the simple and compact structure, good balance, high power density, high thermal efficiency and the like of the horizontally-opposed piston two-stroke gasoline engine are fully used, the engine is highly integrated with the electric generator, and therefore the range extender has a remarkable advantage as a range extender of a pure electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a horizontally opposed balanced gasoline range extender and an operating method thereof. Background technique [0002] As the energy crisis and environmental pollution problems continue to intensify, energy conservation and emission reduction have been mentioned to a strategic height. Judging from the current energy forms, solar energy, hydrogen energy, electric energy and other energy are all green and renewable energy, which will definitely be the future development trend. Judging from the current reality, electric energy as a vehicle power is the closest to the current level of technology and production. [0003] An electric vehicle in the traditional sense refers to a vehicle that uses electric energy to drive an electric motor in whole or in part. The main forms include fuel cell electric vehicles, hybrid electric vehicles and pure electric vehicles. Fuel cell e...
