Embodiment 1

[0075] One end of the Stirling engine is a hot chamber and the other end is a cold chamber. Under the action of different temperatures, it performs periodic compression and expansion in a closed cycle. The gasoline engine forms a reciprocating work through the four strokes of intake, compression, power and exhaust. Combining the Stirling engine and the gasoline engine forms a two-stage power conversion, which greatly improves the power conversion rate of the gasoline engine.

Abstract

The invention discloses an engine, which includes a heating chamber, a cold air buffering chamber and a cold air cylinder. The cold air cylinder is arranged on the cold air buffering chamber, and thecold air cylinder communicates with the cold air buffering chamber; the heating chamber includes a combustion chamber and a hot air cavity, and the combustion chamber communicates with the hot air chamber; a first-level Stirling engine is added in a gasoline engine, and the power converting efficiency of the gasoline engine is improved greatly; a heat conducting device is arranged outside the coolair buffering chamber and includes a cooling tube, a cooling fin, a fixing plate and a heat conducting block, wherein the fixing plate is fixedly connected with the outer side of the cool air buffering chamber, the cooling tube is fixedly connected with the fixing plate, the cooling fin is fixedly connected with the cooling tube, and the fixing plate is fixedly connected between the cooling tubeand the fixing plate; the cooling tube, the cooling fin, the fixing plate and the heat conducting block are all made from flexible metal materials; and contact areas between the cooling tube and outside air are enlarged by the cooling fin, the cooling rate is increased, rigidity reduction of an engine shell due to a high temperature is avoided, and then the integral performance of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of power engines, in particular to an engine. Background technique [0002] With the continuous development of industrialization, the application of engines has become more and more extensive, and the most common applications are in automobiles and aerospace. At present, the most widely used is the internal combustion engine, but the internal combustion engine has the problems of low efficiency conversion and large energy loss; at the same time, the current energy conversion rate of the external combustion engine is also low. [0003] Therefore, in order to solve the problem of low energy conversion efficiency of existing internal combustion engines and external combustion engines, it is necessary to provide an engine with high energy conversion efficiency and excellent performance. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an engine to overco...
