Compressed-air power automobile

Abstract

The invention provides a compressed-air power automobile which comprises an air injection monitoring system. The air injection monitoring system comprises an engine operating condition monitoring module, an expected value calculating module, a sensor module, a difference value calculating module, a difference value comparing module, a deviation state judging module and an engine protecting module, wherein the engine operating condition monitoring module is used for judging whether an engine is in an operating state or not, the expected value calculating module is used for calculating expected air injection pressure, expected air injection amount and expected engine speed, the sensor module is used for measuring actual air injection pressure, actual air injecting amount and actual engine speed, the difference value calculating module is used for calculating a first difference value, a second difference value and a third difference value, the difference value comparing module is used for carrying out comparison on all the difference values with all difference value threshold values, the deviation state judging module is used for determining whether the engine is in a first deviation state or a second deviation state or a third deviation state, and the engine protecting module is used for judging the problem that air injection precision of the engine declines exits and executing an engine protecting measure when any of the first deviation state or the second deviation state or the third deviation state continuously occurs in a preset number of times or for a preset time period.

Description

technical field [0001] The present invention relates to a compressed air powered vehicle, and more particularly, to a compressed air powered vehicle including an air injection monitoring system. Background technique [0002] Most ground vehicles, such as automobiles, trucks, and off-road vehicles, use internal combustion engines that use fuel as a working medium as their power source. On the one hand, this kind of engine using fuel oil as a working medium pollutes the environment due to insufficient combustion of fuel oil, so that the discharged gas contains a large amount of harmful substances and pollutes the environment. The shortage makes the development and utilization of fuel engines more and more restricted. Therefore, the development of new, clean, non-polluting alternative energy sources, and using this alternative energy source as the power source of ground vehicles has become an urgent problem in the development of modern vehicles. Compressed air-powered vehi...

Problems solved by technology

However, this kind of aerodynamic vehicle only uses a mechanical air distributor, which cannot meet the requirements of the injection volume and injection timing of the engine under different operating conditions. Therefore, the compressed air in the air storage tank cannot be utilized to the maximum extent, and the cruising range is limited. certain limit

[0007] None of the aforementioned prior art monitors and controls the process of the air injection of the aerodynamic engine, which makes it difficult to guarantee the working efficiency of the engine, and problems such as the decrease in the accuracy of air injection control caused by system deviation and component aging are unavoidable
