Embodiment Construction

[0014] Such as figure 1 As shown, a valve includes a valve body 6 and an electric terminal seat 7, and there are three links on the valve body, which are respectively the first interface 1, the second interface 2 and the third interface 3; the first interface in the valve body 6 Between 1 and the third interface 3 there is a slider 5 that can slide through electromagnetic actuation, one end of the slider 5 is connected to the spring 4, and the slider 5 is also the spool of the second interface 2 to control the opening of the second interface 2.

[0015] Such as figure 2 As shown, a gasoline engine turbocharger recirculation system that adopts the above-mentioned valve includes an engine 9 and an ECU1 that controls the operation of the engine. The front hose 14 and the throttle valve 13 enter the engine intake manifold 10; the engine exhaust manifold is connected to the inlet of the turbocharger 8, and the exhaust outlet of the turbocharger 8 is connected to the three-way cat...

Abstract

The invention discloses a valve and a system used for the recycling of a turbocharger, wherein, the valve is a three-way magnetic valve, and the recycling system of the turbocharger comprises an engine and an ECU which controls the work of the engine; air is mixed with the waste gas of the recycling outlet of the turbocharger by an air filter, and then enters an engine intake manifold by the front hose of a throttle valve and the throttle valve; an engine exhaust manifold is connected with the inlet of the turbocharger; the exhaust outlet of the turbocharger is connected with a three-way catalysis; the recycling outlet of the turbocharger is also connected with a relief valve; the valve controls the work of the relief valve; and the ECU is connected with a pressure sensor, a throttle valve position sensor and the valve by electricity. The valve is the three-way magnetic valve; a first interface of the valve is connected with a vacuum tank; a second interface is connected with the relief valve, and a third interface is connected with the front hose of the throttle valve. The invention is used for solving the problems of turbocharger noise which is caused by the weak opening of the relief valve ahead of time or slow closing of the valve when the supercharged engine is at emergency deceleration status and the acceleration responsiveness.

Description

technical field [0001] The invention relates to a valve, in particular to a gasoline engine turbocharger relief valve, and also relates to a system in which the valve is used for gasoline engine turbocharger recirculation. Background technique [0002] At present, when the turbocharged engine is in a state of rapid deceleration, the throttle valve is close to fully closed or completely closed, and the supercharger rotor continues to supercharge due to inertia, and a continuously rising pressure is generated in the intake pipe of the supercharger. When the flow rate has decreased but the speed has not decreased in time, it is easy to cause the surge of the engine. At this time, the pressure relief valve is used to open the valve. The input end of the solenoid valve in the control device of the traditional pressure relief valve is the intake manifold. At this time, when the engine decelerates and the vacuum source at the other end of the solenoid valve is not connected, the va...
