How to clean the air inlet of egr valve of automobile

The failure of EGR valve in Pacific automobile network is mostly due to carbon deposition in the passage, which should be cleaned or replaced in time to ensure the normal operation of the engine. Cleaning EGR valve with carburetor cleaner can remove carbon deposits in 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.

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.

If the EGR valve is broken and kept open, it will lead to engine idling flameout, unstable idling, weak acceleration or increased fuel consumption, and it will also be accompanied by the problem of engine power decline; If the EGR valve is broken and kept closed, it will have an impact on automobile exhaust emissions, and the emissions may not meet the standards and fail the annual inspection.

How to clean egr valve? The failure of EGR valve is mostly due to carbon deposition and channel blockage. Cleaning or replacing EGR valve in time is a necessary condition to ensure the normal operation of the engine. Cleaning EGR valve with carburetor cleaner can remove carbon deposits in 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.
