Abstract

The invention discloses a pre-combustion generator. The pre-combustion generator is mounted in an oil spraying device mounting hole on an engine cylinder cover, and comprises a pre-combustion generator body, wherein the pre-combustion generator body is provided with a pre-combustion chamber; the pre-combustion generator body is provided with a spraying hole for communicating the pre-combustion chamber with a combustion chamber; the pre-combustion generator body is further provided with a gas supplying device for supplying gas to the pre-combustion chamber; the pre-combustion chamber is provided with a sparking plug mounting hole; the sparking plug mounting hole is internally provided with a sparking plug; the pre-combustion generator body is further provided with a cooling device. The pre-combustion generator is provided with an independent cooling system, a gas feeding system and a control system so that one independent product is formed and the product can be conveniently applied to a diesel engine to be refitted into a gas engine; the tendency of detonation in a main combustion chamber can be reduced and the compression ratio of the existing gas engine can be increased; a piston and the cylinder cover do not need to be redesigned to change the compression ratio; the heat efficiency of the gas engine can be effectively improved and energy sources are saved.

Description

technical field [0001] The invention relates to a pre-combustion generator for retrofitting a diesel engine into a gas engine. Background technique [0002] The biggest advantage of natural gas as engine fuel is its low pollution. Compared with the gasoline engine, the emission of carbon monoxide is reduced to 1 / 15, the emission of hydrocarbons can be reduced to 1 / 5, the sulfur dioxide is reduced to 4 / 5, and there are no harmful substances such as stupid, lead, and sulfur. In addition, natural gas will not dilute lubricating oil and will not affect the quality of lubricating oil, so it can prolong the service life of engine and engine oil, improve economy and reduce running noise. Our country has abundant natural gas resources, and gas engines have broad development prospects in our country. The gas engines currently in use are mainly based on the original gasoline engine and diesel engine, but when the diesel engine is converted into a gas engine in the prior art, it is n...
