Problems solved by technology

[0003] Traditional internal combustion engines generally discharge high-temperature exhaust gas directly, resulting in serious heat loss
However, the gas working medium in the traditional heat engine needs heat to heat, the conventional heating method is external combustion, and the fuel usage efficiency is also low. Therefore, for the fuel efficiency of the existing internal combustion engine and heat engine, it is necessary to provide Engines for further utilization of waste heat from engine exhaust

Abstract

The invention discloses a three-valve hot-air engine, and the three-valve hot-air engine includes an air cylinder piston mechanism and a combustion chamber. An air cylinder of the air cylinder piston mechanism is provided with an air inlet. An air inlet valve is arranged at the position of the air inlet. The air cylinder of the air cylinder piston mechanism is provided with a reciprocating flow mouth which is provided with a reciprocating flow control valve. The reciprocating flow mouth is communicated with a timing pulse air mechanism through a reciprocating communicating channel. A heat regenerator is arranged on the reciprocating communicating channel. An exhaust air outlet is formed on the air cylinder of the cylinder piston mechanism, and an exhaust valve is arranged at the position of the exhaust air outlet. The combustion chamber is arranged inside the air cylinder piston mechanism. Due to the facts that the combustion motor is combined with the thermomotor, and the air exhausted from combustion motor is regarded as a circular working medium of a thermomotor, the further utility of the waste heat in the exhaust of the engine has the advantages of effectively improving thermal efficiency of the engine, and being simple in structure, strong in practicability, and broad in application prospect.

Description

technical field [0001] The invention relates to the field of thermal power, in particular to a heat engine. Background technique [0002] In recent years, the problems of high energy consumption and high pollution emissions of traditional internal combustion engines have become increasingly prominent. Therefore, heat engines have received extensive attention. However, heat engines heat the working fluid by means of external combustion heating. A working fluid with a higher temperature is obtained, therefore, causing a large amount of chemical loss. Not only that, due to the limited external combustion heating rate, high material requirements, and poor load response, the single-unit power and overall power density of the heat generator are severely restricted, and the use of the heat generator is severely limited in the end. [0003] Traditional internal combustion engines generally discharge high-temperature exhaust gas directly, resulting in serious heat loss. However, ...
