A compressed air or liquid nitrogen-fuel/combustion gas mixed powered automobile

Abstract

The invention relates to a compress air, liquid nitrogen-fuel, or fuel gas mixed power vehicle, which comprises a internal-combustion engine cooling-heating exchange system, a internal-combustion engine waste gas heat exchanger, a energy supplier of compress-air or nitrogen engine, and a vehicle chassis which can driven by internal-combustion engine or/and compressed air or nitrogen engine; when the environment temperature is lower, or needing high driving power, the internal-combustion engine can power vehicle, and the internal-combustion cooling-heating exchange system and the waste gas heat exchanger can supply energy to the energy supply system of compressed air or nitrogen engine; the internal-combustion cooling-heating exchange system can store energy to be supplied to the energy supply system when the internal-combustion engine is not working. The invention can improve the energy utilization and avoid polluting environment.

Description

technical field [0001] The invention relates to a compressed air or liquid nitrogen-fuel or gas hybrid vehicle, which belongs to the technical field of vehicle manufacturing. Background technique [0002] Conventional cars are generally driven by internal combustion engines fueled by diesel, gasoline, and gas. The world's petroleum resources are increasingly depleted, and energy conservation and environmental protection issues have become increasingly important. People have begun to seek new power devices that use solar energy, electric energy, compressed air, or liquid nitrogen as energy sources. [0003] Solar cars and electric cars are currently in the preliminary research stage, and their power devices either have problems such as too low energy density or too much weight, and have not been widely used. [0004] Compressed air or liquid nitrogen powered vehicle is a new type of vehicle that can achieve zero pollution. The heat exchanger technology of compressed air or l...

AI Technical Summary

Problems solved by technology

Compressed air power cylinders should be connected in parallel, series or mixed connection, coupled with the working cylinder of the internal combustion engine, it will inevitably bring about disadvantages such as complex structure and excessive volume; compressed air power cylinders rely too much on the waste heat of the exhaust gas of the internal combustion engine, And sharing the output shaft with the internal combustion engine will cause the internal combustion engine to continue to work, and the working conditions are changeable, which will inevitably affect its energy utilization and emissions
