Self-cooling backheating movable cylinder fuel-air engine and Stirling engine

Abstract

The invention relates to a self-cooling backheating movable cylinder fuel-air engine and Stirling engine. The engine comprises a crankshaft, a connecting rod component, a pipeline, a hydraulic tappet, a cylinder head, a piston ring, a piston, a movable cylinder, a middle cylinder, an outer cylinder, a sensor, a valve component, an electric control hydraulic valve, a nozzle, a high-pressure electronic pump, an electric flow valve, an exhaust gas recirculation system, a booster, a power machine, a valve, a turbine, a compressor and a cooler, and is characterized in that: two internal combustion engines, namely a heat release engine and a heat absorption engine consist of the movable cylinder, the piston fixed in the movable cylinder and the middle cylinder outside the movable cylinder; the engine has a compact structure and is convenient to assemble and maintain; the heat absorption engine absorbs heat from the periphery of the heat release engine and an exhaust gas regenerator to do work and reduce temperature, so that the cylinder temperature is appropriate; a cylinder cooling system is saved; the heat is prevented from being taken away by cooling, exhaust heat is recovered outside, the heat is absorbed inside for doing work and self-cooling, most of consumed heat is recycled, and the heat efficiency of the whole engine is obviously improved; and the engine also can be taken as an air engine, is energy-saving, environmental-friendly, high-efficiency and ideal and can be widely applied to various fields.

Description

technical field [0001] The invention relates to an engine, in particular to a dual internal-combustion fuel-air general engine and a Stirling engine which utilizes fuel and air thermal expansion to perform work, and absorbs heat to perform work and is self-cooled. technical background [0002] The current internal combustion engine has a high cylinder temperature and is prone to knocking, so it must have a cooling system; most of the heat is taken away by the cooling system and exhaust gas, resulting in high heat consumption and low thermal efficiency of the whole machine; it cannot be used for compressed air to start. [0003] The working cycle of the internal combustion engine is carried out at high temperature, and the combustible mixture generates extremely high temperature when it is burned. The piston, cylinder block, cylinder head, etc. are in direct contact with high-temperature gas, and the frictional heat generated by the friction of moving parts is also transmitte...

AI Technical Summary

Problems solved by technology

Only a small part of the heat of the exhaust gas is used, and most of it is wasted

In addition, the cooling system also dissipates part of the heat, as well as the energy consumed by its own operation

The heat consumed is large, the useful heat is small, and the thermal efficiency of the whole machine is low

[0008] The current internal combustion engine cannot be used for compressed air, or the air engine cannot be used as an internal combustion engine. It seems that there is still a lack of fuel-air universal engine
