Power system for composite cycle vehicle

Abstract

The invention provides a power system used for a composite circulation vehicle, belonging to vehicle power technique. The invention relates to a composite circulation vehicle used power system which is provided with dual power source of internal combustion engine power and compressed air power and recovers braking energy and the waste heat of the tail gas of an engine. The invention comprises an engine, an air compressor, a gas storage cylinder, a waste gas heat exchanger, a turbine, a clutch, a central control mechanism and a chassis. A plurality of clutches are connected between the engine and the air compressor, between the engine and the chassis, between the turbine and the chassis, and between the air compressor and the chassis. The air compressor is connected with the gas storage cylinder; the engine and the gas storage cylinder are both connected with the waste gas heat exchanger which is connected with the turbine that is connected with the air compressor. The whole driving system is controlled by the central control system. The invention has the advantages of low oil consumption, small pollution, improving the efficiency of driving system, easily implementing logic control, and being applicable to the development of the power systems of novel vehicles and the reconstruction of the power systems of traditional vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle power, and in particular relates to a driving system of a hybrid vehicle which has dual power sources of internal combustion engine power and compressed air power and utilizes engine waste heat. Background technique [0002] With the improvement of people's living standards, automobiles are widely used, and the number of automobiles increases year by year. The ensuing energy consumption and pollution problems of automobiles have attracted much attention. Ordinary internal combustion engine automobile engine consumes a lot of energy, and its thermal efficiency can reach more than 30% in the best working condition; while in urban working conditions, even when the mechanical transmission mode with high transmission efficiency is adopted, the whole vehicle The thermal efficiency is often lower than 10%. Even when the car is running at the most fuel-efficient speed, the engine is generally running at a...

AI Technical Summary

Problems solved by technology

Compressed air-powered vehicles have zero exhaust emissions, but have poor adaptability to complex working conditions, and need to be equipped with high-pressure storage tanks, making the system more complicated

The internal combustion engine and storage battery hybrid electric vehicles currently under study have complicated driving and control systems, and the performance of the whole vehicle is restricted by the factors of the vehicle battery, and the battery itself still has serious secondary pollution problems.
