Zero leakage external firing heat engine

Abstract

The invention discloses a zero leakage external firing heat engine, which relates to the technical field of heat energy conversion. The zero leakage external firing heat engine aims to solve the problem of the low heat conversion efficiency and insufficient combustion of the conventional internal combustion engine, the problem that the conventional Stirling engine has a low power-to-weight ratio and zero leakage cannot be realized due to difficulties in sealing, and the like. An outward ventilation valve is connected with a closed chamber formed by communicating an air guiding cylinder chamber with the upper part of a dowork cylinder chamber; a conduction start point of the ventilation valve is that an air guiding piston moves between positions which are 20 degrees in front of and behind the top of the high temperature end of the air guiding cylinder chamber; the conduction angle of the ventilation valve 6 is between 5 and 30 degrees; and all movable sealing positions and the outward ventilation port of the ventilation valve are sealed in a closed shell. The zero leakage external firing heat engine can directly and efficiently convert combustion heat energy of fuels into mechanical energy and realize zero leakage; the internal movable sealing part technology of the engine can meet working requirements by adopting the prior art; the power-to-weight ratio is extremely high; and the convention efficiency is 20 percent to 80 percent.

Description

technical field [0001] The invention relates to the technical field of converting thermal energy into mechanical energy. Background technique [0002] Existing internal combustion engines are widely used in various fields, among which the number of automotive applications is the largest, which brings a lot of convenience to human life, but its heat / engine conversion efficiency is generally between 20% and 40%, and the remaining 60% ~80% of the heat energy cannot be used and needs to be discharged outside. At the same time, because the fuel cannot be completely burned, the exhaust gas will emit a large amount of polluting gas into the air, which will seriously pollute the air. According to statistics, these are the main causes of global warming. one of the reasons. It has brought irreparable loss and damage to the future living environment of human beings. [0003] The Stirling engine was invented by Stirling in 1816. Stirling engines are unique heat engines in that their ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a zero-leakage type external combustion heat engine. The present invention is to overcome the low heat conversion efficiency (between 20% and 40%) of existing internal combustion engines, and discharge a large amount of polluting gases into the air due to incomplete combustion. problems, and the existing Stirling engine still has problems such as low power / weight ratio, and difficult sealing to achieve zero leakage, etc.
