Numerical control pneumatic engine

Abstract

The invention discloses a numerical control pneumatic engine, which comprises an energy supply system, an energy conversion system and a control system. The energy supply system consists of a high-pressure air storage tank, a manual valve, a control electromagnetic valve A, a primary heat exchanger, a primary decompression cylinder, a control electromagnetic valve B, a secondary heat exchanger, asecondary decompression cylinder, a control electromagnetic valve C, a quantitative pre-spraying cylinder and a control electromagnetic valve D which are connected in series by pipelines. The energy conversion system comprises a body; a working cylinder is connected with a crank gear through a piston; and a fly wheel is connected with the other end of the crank gear. The control system consists of an electronic control unit, a signal acquisition device and an execution device. The numerical control pneumatic engine uses compressed air or liquid nitrogen, and has the characteristics of no pollution, convenient storage and transportation, simple manufacturing process, high energy efficiency, convenient control and the like, and can be used as a power source for daily short traffic or indoortraffic tools in seriously polluted cities.

Description

technical field [0001] The invention relates to a numerically controlled compressed air or liquid nitrogen power engine used for automobile power, belonging to the field of power trains. Background technique [0002] Automobiles mainly consume fossil fuels such as gasoline, diesel and natural gas as the source of power, and at the same time emit CO to the outside world. x , NO x and CH x Exhaust gases such as harmful substances. While the automobile industry brings vigorous vitality to the economy, it also brings energy crisis and environmental pollution to human society. The depletion of various fossil energy sources has forced more and more people to start exploring new energy sources, and green concept cars in the name of new energy sources have appeared one after another. Compressed air power engine is exactly a typical example of a kind of non-polluting emission green car that conforms to this trend. [0003] The patent No. is 01108350.6, and the patent disclosed b...
