Effects of Injector Carbon Buildup

As one of the key components of the EFI engine injector nozzle, its work well or badly will seriously affect the performance of the engine. Injector nozzle clogging will seriously affect the performance of the car. The reason for clogging is due to carbon deposits in the engine on the injector nozzle or due to impurities in the fuel and other clogging of the injector nozzle path. After the car has been driven for some time, certain deposits will form in the fuel system. The formation of deposits and automotive fuel directly related to: first of all, because the gasoline itself contains gums, impurities, or storage and transportation process to bring in the dust, impurities, etc., accumulated over time in the automotive fuel tank, fuel inlet pipe and other parts of the formation of similar sludge deposits; and second is due to the gasoline in the unstable components at a certain temperature to react, the formation of gelatinous and resinous viscous material. These sticky substances are in the injector nozzles, intake valves and other parts, and when burned, the deposits turn into hard carbon deposits.

In addition, due to urban traffic congestion, the car is often in a low-speed and idling state, which will aggravate the formation and accumulation of these deposits. Fuel system deposits are very harmful. Deposits will block the needle valve of the injector nozzle, valve holes, affecting the working performance of the precision components of the electronic injection system, resulting in a decline in power performance; deposits in the intake valve to form carbon, resulting in its closure is not strict, resulting in unstable engine idling, increased fuel consumption and worsening emissions; deposits in the top of the piston and the cylinder head, and other parts of the formation of hardened carbon, due to the carbon of the high heat capacity and thermal conductivity is poor, easily caused by the engine vibration and other faults; in addition, it will also be the formation of hard carbon in the top and cylinder head and other parts, due to high heat capacity and poor thermal conductivity, easy to cause In addition, it will shorten the life of the three-way catalytic converter.
