Problems solved by technology

At the same time, the patent also mentions the combination of internal combustion engine power and electric power, but internal combustion engine power and electric power are only used as backup power when compressed air power is not used or is inconvenient.
[0004] The above-mentioned cars powered by compressed air at home and abroad have the following problems: during use, due to the large heat absorption, there are serious problems of condensation and ice blockage, insufficient heat exchange leads to low engine efficiency, and the compressed air Filling and storage require special equipment, and the maximum mileage at one time needs to be further improved
Some are complex in structure and inconvenient to use, and some are difficult to be practical

Embodiment Construction

[0016] figure 1 Among them, the cold compressed air enters the heat exchanger from the air inlet 2 of the heat exchanger 3, and after being heated, enters into a group of compressed air power cylinders 11 and 11' of the engine from the air outlet 4 through the air delivery pipe 6. After the compressed air expands and does work in a group of compressed air power cylinders 11 and 11', it decompresses and absorbs heat. The compressed air now still has a certain residual pressure, and enters a group of internal-combustion engine power cylinders 8 and 8 ' as the intake air of the internal-combustion engine power cylinders through air pipes 10 and 13, which plays the role of air intake boosting. The fuel inlets 9 and 9' of a group of internal combustion engine power cylinders 8 and 8' are fed with fuel oil or gas fuel respectively, and the fuel is burned in the internal combustion engine power cylinders 8 and 8' to perform work, and the discharged hot exhaust gas passes through the ...

Abstract

A car engine using compressed air and fuel oil / gas as power source has more cylinders, Part of then uses compressed air as power source and other are IC engien unit whose exhausted gas is used to heat the input air of said non-IC unit via heat exchanger. The exhausted gas of said non-IC unit is used as the input gas of IC engine unit for boosting the input gas. Its advantages are reasonable structure, high efficiency and low environmental pollution.

Description

technical field [0001] The invention relates to a hybrid automobile engine powered by compressed air and fuel / gas internal combustion engine, in particular, it can use fuel / gas alone or compressed air alone as power, and can also use fuel / gas and compressed air at the same time For powering a hybrid car engine. Background technique [0002] Automobiles are the most commonly used means of transportation in human society, but the fuel combustion of internal combustion engine-powered vehicles will produce emission pollution and consume a large amount of non-renewable mineral resources, so people have been exploring new economical and practical vehicles that can reduce pollution. [0003] Compressed air powered vehicles are a typical example of a non-polluting emission vehicle produced in response to this trend. Frenchman Guy Négre patented a pneumatic car engine in 1991. According to their introduction, the pneumatic vehicle designed by them is equ...
