Cleaning method of injector clogging:
The injector is one of the key components of the EFI engine, and its working condition will directly affect the performance of the engine. However, many car owners do not pay attention to the engine nozzle cleaning, or that the engine nozzle to a long time before the need to clean - do not know that the nozzle clogging will have a serious impact on the performance of the car!
The formation of deposits and the use of fuel has a direct relationship: First, the gasoline itself contains gum, impurities, or storage and transportation process of dust, impurities, etc., will be in the car fuel tank, oil intake pipe and other parts of the formation of similar sludge deposits; Second, the gasoline in the unstable components will be reacted at a certain temperature, the formation of gelatinous and resinous viscous material. These sticky substances will turn into hard carbon deposits when burned in the injector nozzles, intake valves and other parts of the vehicle.
Deposits will also form carbon deposits in the intake valve, causing it to close poorly, resulting in unstable engine idle, increased fuel consumption and worsening exhaust emissions; deposits will form hard carbon deposits in the top of the piston and the cylinder head and other parts of the carbon, due to the carbon's high heat capacity and poor thermal conductivity, which is likely to cause the engine vibration and other malfunctions; in addition to shortening the life of the three-way catalytic converter.
Additionally, due to urban traffic congestion, cars are often driven at low speeds and idling, adding to the formation and accumulation of these deposits. Fuel system deposits have a great harm, deposits will block the injector nozzle needle valve, valve hole, affecting the electric injection system precision parts of the working performance, resulting in a decline in power performance.
The use of gasoline quality is poor or driving time is longer vehicles, if the long-term not clean injector nozzles, this clogging phenomenon will become increasingly serious, thus causing the engine fuel injection is not smooth, the injection angle and atomization of poor, resulting in engine idling, acceleration, or full-load conditions when the work is not good, so that the engine power down, fuel consumption, emissions pollution increases, and even make the engine can not work. Therefore, Yantai car rental to remind owners should be regularly cleaned and tested injector nozzle to ensure that it works well.
When there is a slight clogging of the injector nozzle, there is also a certain impact on the car's condition. Sometimes there will be such a failure: hang a gear, start, the car is a little shaky, and so hang a high gear acceleration, such a phenomenon disappeared, if the car's various sensors work normally, the throttle body has been cleaned, the circuit is also normal, it is likely to be a slight clogging of the injector nozzles.
But when accelerating in higher gears, it is possible that the slight gunk was sprayed away again (dissolved) and the car's performance was restored. This kind of slight clogging of the injectors usually does not need to be cleaned. This is because the slight gunk can be dissolved. Therefore, if you run on the highway often, you can reduce the formation of carbon deposits.
How well the injectors work plays a fundamental role in the power of each engine. Poor fuel will lead to injector nozzles do not work well, so that the cylinder carbon buildup is serious, cylinder barrel, piston ring accelerated wear, resulting in unstable idle speed, fuel consumption, acceleration, acceleration, startup difficulties and emissions exceeded the standard; serious clogging of the injector nozzles, damage to the engine.
Therefore, it is necessary to clean the injector nozzle at regular intervals, and long-term non-cleaning or frequent cleaning of the nozzle will have a bad effect. As for the frequency of cleaning, according to the condition of the car and the quality of the fuel usually used to determine, in general, now Yantai car rental recommended that the owner of the car in about 20,000 to 30,000 kilometers for cleaning. Good condition, good fuel quality can be extended to about 40,000 to 60,000 kilometers.
