Intake pressure balancing adjuster for supercharged and intercooled gas engine

Abstract

Disclosed is an intake control device for a supercharged and intercooled gas engine. By coaxial control bidirectional pressure relief means, the output pressure of two superchargers is simultaneously controlled by the aid of one device, the technical problem of unbalanced output pressure of the two superchargers is solved, a complicated structure respectively controlling the output pressure of the two superchargers is simplified, functional cost is reduced, reliability is improved, the influence of a balancer on maximum intake flow of the engine is thoroughly eliminated, and the maximum output power of the engine is improved. The device is applicable to the gas engine with air and gas respectively supercharged and intercooled.

Description

technical field [0001] The utility model relates to a volume-adjusting air intake control device for an internal combustion engine, which is suitable for a supercharging and intercooling gas engine. Background technique [0002] Patent application number 201310130697.X (a new air intake mixing system for supercharged intercooled gas engines), in order to solve the safety problem of intercooler superchargers of supercharged intercooled gas engines, the method of separately supercharging air and gas is adopted , relying on the two devices of the balancer and the synchronous pressure reducer, the two pressurized air sources (gas supercharger and air supercharger) with unequal output pressures (gas supercharger and air supercharger, under normal circumstances, the gas supercharger is a "Roots blower", The air booster is a "turbocharger") to generate two air pressures (air pressure and gas pressure) that are always balanced when they are delivered to the mixer; it can be seen tha...

[0002] Patent application number 201310130697.X (a new air intake mixing system for supercharged intercooled gas engines), in order to solve the safety problem of intercooler superchargers of supercharged intercooled gas engines, the method of separately supercharging air and gas is adopted , relying on the two devices of the balancer and the synchronous pressure reducer, the two pressurized air sources (gas supercharger and air supercharger) with unequal output pressures (gas supercharger and air supercharger, under normal circumstances, the gas supercharger is a "Roots blower", The air booster is a "turbocharger") to generate two air pressures (air pressure and gas pressure) that are always balanced when they are delivered to the mixer; it can be seen that using two devices to achieve one purpose, the structure is naturally complicated and the cost is high ; On the other hand, because the intake air passes through the balancer, the balancer becomes a part of the intake path, which has a resistance effect on the intake air flow, and has a certain degree of negative impact on the maximum intake air volume of the engine, thereby affecting the maximum output power of the engine
