Problems solved by technology

[0002] The efficiency problems and pollution emission problems of volumetric power mechanisms represented by gasoline engines and diesel engines have not been well resolved. The fundamental reason is that their timing combustion methods and the volume changes in the compression process and expansion process are the same. These two major problems are caused by the basic structure of this type of engine, which cannot be changed, so a new type of engine needs to be invented

Abstract

The invention discloses a reciprocating piston mechanism engine. The reciprocating piston mechanism engine comprises a reciprocating cylinder piston mechanism for compression, a gas compression and rotation control valve, a continuous working-medium heater, a gas expansion and rotation control valve and a reciprocating cylinder piston mechanism for expansion. The gas compression and rotation control valve and the reciprocating cylinder piston mechanism for compression are arranged correspondingly to constitute a part of a reciprocating piston rotation valve compression unit, the gas expansion and rotation control valve and the reciprocating cylinder piston mechanism for expansion are correspondingly arranged to form a part of a reciprocating piston rotation valve expansion unit, a working-medium outlet of the reciprocating piston rotation valve compression unit is communicated with a working-medium inlet of the reciprocating piston rotation valve expansion unit via the continuous working-medium heater, the ratio of the volume of the working-medium inlet of the reciprocating piston rotation valve expansion unit to that of the working-medium outlet of the reciprocating piston rotation valve compression unit is larger than one. The reciprocating piston mechanism engine is few in parts, low in cost, stable in operation and few in pollutant emission, has high power density and efficiency and can be applied to various fuels.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a reciprocating piston mechanism engine. Background technique [0002] The efficiency problems and pollution emission problems of volumetric power mechanisms represented by gasoline engines and diesel engines have not been well resolved. The fundamental reason is that their timing combustion methods and the volume changes in the compression process and expansion process are the same. These two major problems are caused by the basic structure of this type of engine, which cannot be changed, so a new type of engine needs to be invented. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: The present invention provides a reciprocating piston mechanism engine, comprising a reciprocating cylinder-piston mechanism for compression, a gas compression rotary control valv...
