Hybrid engine using compressed air and gasoline as power source and using method

Abstract

The invention discloses a hybrid engine using compressed air and gasoline as power sources and a method for using the same, and belongs to the technical field of new energy air-powered engines. On the basis of an original four-stroke engine, a compressed air device and a fuel mode and pneumatic mode switching device are added, and the fuel tail gas is utilized to heat the compressed air. The compressed air device comprises an air storage tank and a set of an intake and exhaust mechanism, an original intake valve of the engine is stopped and a hollow valve rod of the pneumatic system is switched on, so that the engine is switched into a two-stroke pneumatic working mode; and the compressed air hollow valve rod is closed and the original intake valve of the engine is started, so that the engine is switched into a fuel working mode. The compressed air is used for driving the engine to work, so that the discharge of tail gas of vehicles is reduced; and the fuel working mode of the engine is kept, and the residual heat of the tail gas of the fuel is utilized, so that the energy utilization rate of the compressed air is increased, and the problem that the driving range of the pure compressed air vehicles is not long enough is solved.

Description

technical field [0001] The invention relates to a hybrid engine using compressed air and gasoline as power sources and a method for using it, belonging to the field of new energy pneumatic engines. Background technique [0002] The emergence of the internal combustion engine has greatly promoted the progress of human society. However, with the rapid entry of automobiles into ordinary people's homes, energy and environmental issues have become increasingly prominent. Major industrial countries in the world have begun and have achieved results in the field of new energy vehicles. my country is also developing in the field of electric vehicles and hybrid vehicles There have been innovative achievements, but the development of pneumatic vehicles powered by compressed air has just started. [0003] Pneumatic engine refers to the use of compressed air or liquid nitrogen as a power source to drive the car. Pneumatic engine is getting more and more attention due to its advantages of...

Problems solved by technology

Although the thermal efficiency of the traditional internal combustion engine is high, the energy waste generated by its combustion is huge. The heat balance research of the internal combustion engine shows that the power output of the internal combustion engine generally only accounts for 30%-45% (diesel engine) or 20%-30% (gasoline engine) of the total energy released by fuel combustion. , about 30% of the energy is taken away by the exhaust of the internal combustion engine
