Installation position of egr valve

Install egr valve in engine compartment. Before disassembly, the battery should be powered off, then the fixing screws on the egr valve should be removed one by one, and finally the plugs on the intake pipe, egr valve and vacuum air regulator should be removed and pulled out. Exhaust gas recirculation valve is the valve of exhaust gas recirculation system. If the EGR valve fails, there will be phenomena such as extremely unstable idle speed or even flameout, flashing fault lights, annual emission failure, engine oil combustion, blue smoke from tail gas and so on. When the EGR valve is always open, it will emit black smoke, the acceleration is weak, and the fuel consumption will increase. Accidentally adding low-purity gasoline or fuel treasure to the car may cause sudden damage to the exhaust valve (EGR valve). Abandoned valves work at high temperature of the engine, which will age after a long time, and the valve cover gasket and skirt will also age. The function of exhaust valve is to appropriately reduce fuel consumption, improve engine efficiency, reduce exhaust temperature and reduce the generation of nitrogen oxides and carbon monoxide. The failure of EGR valve is mostly caused by carbon deposition in the passage, so the EGR valve should be cleaned or replaced in time to ensure the normal operation of the engine. Clean exhaust gas recirculation valve. Carburetor cleaner can be used to remove carbon deposits in air intake, throttle and exhaust gas recirculation valve. For the connecting pipe between the exhaust gas recirculation valve and the air inlet, the pipe is slender and curved, and it can be sprayed with cleaning agent for combustion. After natural cooling, take out the internal carbon deposit.
