Energy-saving environmental-friendly hybrid electric vehicle

Abstract

The invention relates to an energy-saving environmental-friendly hybrid electric vehicle, comprising a vehicle chassis assembly, a fuel engine, a compressed air engine, an air compressor, an air tank, a reducing valve, a control valve and a power control assembly. The fuel engine is the primary power source of the vehicle and the compressed air engine is the secondary power source; the output of the fuel engine and the output of the compressed air engine are connected to a driving shaft of the vehicle chassis assembly through a clutch, a power synthesis device and a speed changer; the driving shaft or a transmission shaft of the vehicle chassis assembly is connected with a power shaft of the air compressor; the output of the air compressor is connected with the air tank; an output end of the air tank is connected with the compressed air engine through the control valve and the reducing valve; and the fuel engine, the air compressor, the air tank, the control valve and the vehicle chassis assembly are under the connection control of the power control assembly. The invention can effectively reduce the operation cost, realize the storage of the redundant energy, improve the conversion efficiency, decrease the exhaust emission, and prevent the secondary pollution of the environment.

Description

Technical field: [0001] The invention relates to the technical field of transportation, in particular to an energy-saving and environment-friendly hybrid electric vehicle. Background technique: [0002] As countries around the world become more and more short of energy and environmental protection measures are becoming more and more stringent, there are more and more alternatives to fuel engine vehicles. Such as hydrogen energy vehicles, fuel cell vehicles, pure electric vehicles, aerodynamic vehicles, hybrid vehicles, etc. But currently the most practical and commercialized only hybrid vehicles, pure electric vehicles and aerodynamic vehicles. [0003] Air-powered vehicles are powered by compressed air stored in air tanks, thus saving energy and causing no pollution. However, due to the limitation of the interior space of the automobile, neither the air storage tank nor the engine can be made too large, so the power output of the automobile and the stroke of a single infl...

AI Technical Summary

Problems solved by technology

The first is that the energy conversion rate is low. The kinetic energy of the vehicle is converted into electrical energy, the electrical energy is stored in the battery (electrical energy is converted into chemical energy), the battery releases electrical energy (chemical energy is converted into electrical energy), and the electrical energy drives the motor to convert into kinetic energy. There are four times in the whole process. Energy conversion, theoretically less than 20% efficient

Secondly, the life of the storage battery is short, the replacement cost is high, and there are still problems of large environmental pollution in production and destruction
