    Nozzle - Nozzle principles

    Nozzle is actually a simple solenoid valve, when the electromagnetic coil when energized, produce suction, needle being sucked on, open the nozzle, the fuel needle through needle head and the nozzle axis between
    Annular gap emit high speed to form mist, conducive to full combustion.
    Nozzle - Nozzle role
    Gasoline direct injection engines the most sophisticated parts - Nozzle
    EFI engine, as one of the key components of nozzle, it will seriously affect the work of good or bad performance of the engine. Nozzle plug will seriously affect vehicle performance. Block
    Cyprus is due to coke deposition inside the engine or the fuel injectors on the fuel impurities such as blockage of the nozzle channel. Car running for some time, the fuel system will
    Formation of certain deposits. Sediment formation and the fuel directly related: the first is due to gasoline itself contains resin, impurities, or into the dust during storage and transportation, miscellaneous
    Quality, etc., accumulate in the vehicle fuel tank, into the tubing and other parts of the formation of similar sediment sludge; secondly because of the volatile components of gasoline under certain temperature reaction,
    The formation of thick resin and resin-like material. The viscous material in the fuel injectors, intake valves and other parts of the combustion, the sediment becomes hard coke. In addition, because urban traffic
    Congestion, often in low speed and idling car state, but will increase the formation and accumulation of these sediments. Great harm fuel system deposits. Sediment can clog the nozzle
    Needle valve hole, affect sophisticated electronic injection system component performance, resulting in dynamic performance degradation; sediment formed coke in the intake valve, causing the closure of lax, leading to
    Engine idle speed instability, increased fuel consumption and emissions associated with deterioration; sediment in the top of the piston and cylinder head and other parts of the formation of hard coke, coking of the heat capacity as high conductivity
    Heat is bad, prone to violent earthquakes and other engine failure; There will also shorten the life of catalytic converters. The work of good or bad injectors on the engine's power to play each play a fundamental
    Role. As the result of poor fuel injector work not working, so that the cylinder coke serious; cylinder, piston ring wear accelerated, resulting in unstable idle speed, fuel consumption increased to speed up the weak
    Starting difficulties and excessive emissions, will be completely blocked nozzle serious damage to the engine. Therefore, regular cleaning fuel injectors clean for long periods or frequently cleaning nozzles are
    Cause bad influence. As for the cleaning of the time, according to vehicle speed, and usually increases the quality of the fuel to determine, in general, and now most of the user is about 2 ~ 30 000 km
    Cleaning. Vehicle condition is good, fuel quality can be extended to 60,000 km in about 4. When the nozzle slightly closed, also have some impact on vehicle condition. Sometimes this occurs
    Fault: hang a block, start the car some jitter, so hanging high, acceleration, this phenomenon disappeared, assuming all sensors working properly the car, valve are clean
    However, the circuit is normal, it is likely that a slight blockage of the nozzle. But the high-gear acceleration, there may be mild gum has been sprayed away (dissolved), and vehicle performance has returned
    The. This small plug nozzle of the situation, generally do not wash. Because of minor gum can be dissolved out. Therefore, in daily driving, you should always run a high run
    Speed in order to reduce the possibility of coke into lines. When gasoline or poor quality of vehicles traveling a long time, if long-term non-cleaning nozzle, this block will become even more serious
    , Causing poor engine fuel injection, injection angle and poor atomization, resulting in engine idle speed, speed or full load condition when the work is not good, makes the engine power down, oil
    Increased consumption, increased pollution emissions, and even so the engine does not work. Therefore, regular inspection nozzle carefully cleaned to ensure good work.
