Pneumatic air distributing engine

Abstract

The invention relates to a pneumatic air distribution engine which can significantly improve thermal efficiency and reduce pollution emission, production cost as well as maintenance expense. By adopting the novel pneumatic air distribution technology, the pneumatic air distribution engine can drive a piston to do rotation with variable angular velocity or with constant angular velocity by relying on gas pressure and a control mechanism, thus meeting the basic requirements of the Otto cycle in the way of changing the motion property of the key components of the engine. The pneumatic air distribution engine adopts high-temperature resistant structure ceramics as the high-temperature resistant components of the engine, abandons a sealing system and a valve structure of the traditional engine, simplifies a cooling and lubricating system and is simpler in structure and cheaper in price than any traditional engines. By adopting two transduction ways, namely, piston way and turbine way, the pneumatic air distribution engine has extremely high volumetric efficiency, combustion efficiency, mechanical efficiency as well as thermal efficiency when working under the condition of high temperature, high speed and high compression ratio, and shows the characters of the existing shaft power engine such as low fuel consumption, low emission, low production cost and little maintenance. Diagram 1 is the front view (omitted in appendix) of the engine, and A-A is the sectional view thereof.

Description

technical field [0001] This invention relates to internal combustion engines, and more particularly to rotary piston and turbo compound engines. Background technique [0002] The internal combustion engine converts the chemical energy of the fuel into mechanical energy by compressing the working fluid, adding heat to the working fluid, and utilizing the thermal expansion of the working fluid to do work. The compression method of the working medium is different, and the effect on the environment is also different. The turbine uses impeller machinery to realize the compression and work of the working medium, and a large amount of working medium gas is required to participate in the work. The gas after doing work still has a relatively high temperature, and because the mass of the working fluid is very large, the heat energy discharged with the tail gas is also relatively large. The piston machine relies on the volume change of the closed container to realize the compression ...

Problems solved by technology

[0004] Although the performance of reciprocating piston engines is increasing day by day, the cost has also increased

Moreover, due to the inevitable inertial force limitation produced by the reciprocating mass of the valve transmission mechanism and the piston connecting rod device, its performance will continue to be greatly improved, and there are certain difficulties.

The triangular rotary piston engine has no reciprocating mass and successfully avoids the limitation of inertial force, but it also suffers from the Coriolis force, which makes the cylinder surface easy to form vibration marks, and the sealing system is far less effective than the reciprocating piston engine, resulting in idling Unstable, easy to overspeed without load, poor durability, poor reliability, high manufacturing cost, and large exhaust pollution. Under the conditions of modern stringent low pollution and low fuel consumption standards, its overall performance level must exceed that of reciprocating piston engines. Still need to be further improved and perfected
