Problems solved by technology

[0002] 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 the external combustion type, and the fuel usage efficiency is also low. Therefore, it is necessary to provide a fuel utilization efficient engine

Abstract

The invention discloses a hot-air engine with three types of doors. The hot-air engine with the three types of doors comprises an air cylinder piston mechanism and an auxiliary air cylinder piston mechanism. The air cylinder piston mechanism is internally provided with a combustion chamber. An air cylinder of the air cylinder piston mechanism is provided with an exhaust port and a reciprocating circulation port. An air cylinder of the auxiliary air cylinder piston mechanism is provided with an air inlet and an auxiliary reciprocating circulation port. An air inlet door, An exhaust gas door, a reciprocating circulation control door and an auxiliary reciprocating circulation control door are correspondingly arranged on the air inlet, the exhaust port, the reciprocating circulation port and the auxiliary reciprocating circulation port. The reciprocating circulation port is communicated with one end of a heat regenerator, and the other end of the heat regenerator is communicated with the auxiliary reciprocating circulation port. An internal-combustion engine cycle is combined with a thermomotor cycle, exhaust gas of the internal-combustion engine serves as a circulation working medium of a thermomotor so that waste heat in the exhaust gas of the internal-combustion engine is further utilized, and thermal efficiency of the engine is effectively improved.

Description

technical field [0001] The invention belongs to the field of thermal power, in particular to a heat engine. Background technique [0002] 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 the external combustion type, and the fuel usage efficiency is also low. Therefore, it is necessary to provide a fuel utilization Efficient engine. Contents of the invention [0003] In order to solve the problems existing in the above-mentioned prior art, the technical scheme that the present invention proposes is as follows: [0004] Scheme 1: A three-type door hot gas engine, including a cylinder-piston mechanism and an auxiliary cylinder-piston mechanism, the cylinder of the cylinder-piston mechanism is provided with an exhaust port, the exhaust port is provided with an exhaust valve, an...
