Reciprocating heat accumulating type internal combustion engine for air inlet and air outlet through scavenging duct

Abstract

A reciprocating heat accumulating type internal combustion engine for air inlet and air outlet through a scavenging duct comprises a compression air cylinder, a heat accumulator, a communicated pipe, a combustion chamber and an expansion air cylinder. The reciprocating heat accumulating type internal combustion engine is characterized in that the heat accumulator is located in a channel of the communicated pipe connecting the compression air cylinder and the expansion air cylinder, the compression air cylinder is divided into a pre-compression cavity and a compression cavity through a piston, and the pre-compression cavity and the compression cavity are connected through the scavenging duct. According to the basic operating principle, when the piston of the compression air cylinder moves towards the upper stopping point from the lower stopping point, the air is fed into the pre-compression cavity, the air in the compression cavity is compressed, the compressed air flows through the heat accumulator to be heated and enters the combustion chamber to be burned with the fuel, a piston of the expansion air cylinder moves downwards from the upper stopping point, and fuel gas expands and acts. When the piston of the air cylinder moves upwards, the piston of the compression air cylinder moves downwards, the acting fuel gas gets out of the expansion air cylinder and reversely passes a combustor and the heat accumulator reversely to heat the heat accumulator, the fuel gas temperature is reduced, the fuel gas enters the compression cavity and is exhausted through an exhaust outlet, fresh air enters the compression cavity through the scavenging duct, and a power circulation is finished.

Description

technical field [0001] The invention relates to an engine, which is a reciprocating regenerative internal combustion engine utilizing a scavenging channel for intake and exhaust. Background technique [0002] The engine generally refers to a heat engine, which is a power device that converts fuel or other energy into heat energy of the working medium inside the engine, and further converts it into mechanical energy. The internal combustion engine is a traditional and widely used engine, which has important applications in industry, transportation and other industries. As the name suggests, an internal combustion engine is a fuel that burns inside cylinders to do work, the most common being gasoline and diesel engines. Because fuel combustion is carried out under short-term, intermittent and other limited conditions, resulting in insufficient fuel combustion, serious exhaust pollution, poor efficiency in variable working conditions, engine wear, high maintenance costs, high ...
