Intake and exhaust system of gas engine

Abstract

The invention belongs to the technical field of gas engines, and particularly relates to an intake and exhaust system of a gas engine. The intake and exhaust system comprises a prefilter, an intake manifold, an air filter, an air filter maintenance indicator, a turbocharger, a water-cooling intercooler, an exhaust manifold and an exhaust silencer. The prefilter is connected with the turbocharger through the air filter. The turbocharger is connected with the intake manifold which is connected with an air inlet of a cylinder of the gas engine. An air outlet of the cylinder of the gas engine is connected with the exhaust manifold which is connected with the exhaust silencer. Compared with the prior art, by arranging the water-cooling intercooler, the disadvantage due to temperature rising after a gas mixture of air and gas passes through the turbocharger can be reduced; and part of cooling liquid out of a water pump is utilized and flows to the water-cooling intercooler, so that the temperature of the gas mixture is lowered, more air can be pressed into the cylinder of the engine, the gas mixture of the engine can be completely and fully burnt, and larger power output is generated.

Description

Technical field [0001] The invention belongs to the technical field of gas engines, and in particular relates to an intake and exhaust system of a gas engine. Background technique [0002] In recent years, the number of cars in my country has been increasing linearly, and the density of cars has become higher and higher. At the same time, my country’s smog weather has become more and more frequent and the scope of influence has become wider and wider. The PM2.5 index remains high and air pollution. Become the focus of discussion from all walks of life. According to data, from the perspective of the cause of the haze weather in Beijing, cars accounted for 22.2%, coal-fired 16.7%, dust accounted for 16.3%, and industry accounted for 15.7%. It can be seen that automobile exhaust has played a major role in the formation of haze weather. Currently, automobile engines mainly use gasoline and diesel as fuels. However, increasingly stringent emission regulations require automobiles to ...

AI Technical Summary

Problems solved by technology

[0005] However, in the prior art, the filtration performance of the intake and exhaust system of the gas engine is not good, which may easily cause early wear and tear of the engine, and the power output is not enough, and the exhaust gas easily pollutes the environment
