How to clean the exhaust gas of Ricky pickup circulation valve

When cleaning the EGR valve, carburetor cleaner can be used to remove the carbon deposits in the air intake, throttle and EGR valve. For the connecting pipe between EGR valve and air inlet, the pipe is slender and curved, so it can be sprayed with cleaning agent to burn it, and then gently knocked out after natural cooling. The failure of EGR valve is mostly due to carbon deposition and blockage in the passage, so the EGR valve should be cleaned or replaced in time to ensure the normal operation of the engine.

Introduction of EGR valve

EGR valve, also known as exhaust gas recirculation valve, is a mechatronics product installed on diesel engine to control exhaust gas recirculation of intake system, and it is a very important and key component in exhaust gas recirculation device. Its function is to control the amount of exhaust gas entering the intake manifold and make a certain amount of exhaust gas flow into the intake manifold for recycling.

If the egr valve of the EFI rail is broken, it will affect the normal operation of the engine, and the car will have unstable idle speed or idling flameout, flashing fault lights, burning oil, power decline, black smoke from the exhaust pipe and other phenomena, which will affect the performance of the car.
