Novel air inlet mixing system for supercharged and inter-cooling gas engine

Abstract

The invention discloses an air inlet mixing system for a supercharged and inter-cooling gas engine. A sequence structure of first supercharging and then mixing is adopted, when the engine tempers, an intercooler and a supercharger can not be burnt and exploded, and the air inlet mixing system is simple, reliable, safe and durable.

Description

technical field [0001] The invention belongs to the field of gas engines. Background technique [0002] Supercharging and intercooling technology is an effective way to increase the power per liter of internal combustion engines. It has been widely used in the field of diesel engines. However, gas engines with lower power per liter than diesel engines and need to increase power per liter rarely see supercharged and intercooling products. The reason is that Existing mechanically controlled intake air mixing systems for gas engines (proportional mixers, venturi mixers, pressure reducing regulators) do not work well with varying air input pressures, so when used in supercharged intercooled gas engines The sequence of mixing first and then supercharging has to be adopted. In this structure, when the engine is working, the intercooler supercharger is filled with a large amount of combustible mixer. Gas will burn and explode, causing damage to the supercharger of the intercooler,...

[0002] Supercharging and intercooling technology is an effective way to increase the power per liter of internal combustion engines. It has been widely used in the field of diesel engines. However, gas engines with lower power per liter than diesel engines and need to increase power per liter rarely see supercharged and intercooling products. The reason is that Existing mechanically controlled intake air mixing systems for gas engines (proportional mixers, venturi mixers, pressure reducing regulators) do not work well with varying air input pressures, so when used in supercharged intercooled gas engines The sequence of mixing first and then supercharging has to be adopted. In this structure, when the engine is working, the intercooler supercharger is filled with a large amount of combustible mixer. Gas will burn and explode, causing damage to the supercharger of the intercooler, and in severe cases, causing personnel safety accidents. This factor has always hindered the application of supercharged intercooling technology in the field of gas engines; The gas mixing system (gas electronic control intake mixing system) can realize the sequence of supercharging first and then mixing. In this structure, when the engine is working, the intercooler supercharger is filled with air. When the engine generates back combustion, the intercooler The air in the supercharger will not burn and explode, which solves the safety problem of the intercooler supercharger of the supercharged intercooled gas engine. However, due to the complex structure and high cost of use and maintenance of this electronically controlled intake air mixing system, currently Economic conditions for widespread application are not yet available
