Cylinder of piston engine

Abstract

The invention discloses a cylinder of a piston engine, comprising a cylinder cover, an inner wall and an outer wall, wherein the outer wall is arranged at the periphery of the inner wall; the cylindercover is fixedly connected with the inner wall; the outer wall is provided with a cooling channel the upper end of which is connected with a fuel inlet, and the lower end thereof is connected with afuel outlet; the fuel inlet and the fuel outlet are both arranged on the outer wall; fuel enters the cooling channel from the fuel inlet; after the fuel flows through the cooling channel, the temperature of the fuel is increased, and the temperature of the cylinder is reduced; and the fuel flows out from the fuel outlet. As the cooling channel is arranged on the outer wall of the cylinder, the engine can be effectively cooled by heat exchange, and the utilization rate of the energy is increased by more than 10%. The fuel oil is heated by the cylinder before entering the cylinder, so that the atomization and the gasification performances of the fuel can be improved, and the emission of harmful gases such as carbon monoxide and the like can be reduced; furthermore, the integration between the cylinder and a fuel oil channel effectively reduces the volume and the weight of the piston engine, and leads the minitype piston engine to use high-heating value fuels such as diesel oil and the like to be possible.

Description

technical field [0001] The invention relates to a cylinder of a piston engine and belongs to the technical field of engines. Background technique [0002] In order to improve the performance of the piston engine, achieve greater power output, reduce fuel consumption and improve stability, the main method in terms of thermodynamics is to continuously increase the compression ratio of the engine, so the working load of the various parts of the engine, especially the heat load will become more and more In order to ensure the reliable operation of the engine and have a long service life, it is necessary to take effective measures to cool the hot-end parts, and the effective cooling of the hot-end parts of the piston engine matches the overall performance and weight of the engine to a large extent. The bottleneck of the development of the piston engine. [0003] The existing cooling structure is becoming more and more complex, but the improvement of cooling effect is much slower...
