Original Bosch injectors DLLA143P485 excavator

DLLA143P485 the injector nozzle of one of the key components of EFI engine, it works good or bad will seriously affect the engine performance. Nozzle blockage will seriously affect vehicle performance. Blockage is due to the engine coke deposited on the nozzle or due to impurities in the fuel clogging the nozzle passage. After the car running for some time, the fuel system will form some sediment. Deposit formation and automotive fuel directly related: first is due to gasoline itself contains resin, impurities, or the storage and transportation process into the dust, and other impurities accumulate in the vehicle's fuel tank, into the tubing and other parts of the formation of sludge deposition similar thereof; secondly because of the unstable ingredient in gasoline reacts at a certain temperature, the formation of gum and resin-like viscous material. The viscous material in fuel injectors, intake valves and other parts, burning, sediment becomes hard coke. In addition, due to urban traffic congestion, often in low speed and idling car state, but will increase the formation and accumulation of these deposits. Great harm fuel system deposits. Sediment can clog the nozzle needle valve, the valve hole, the impact of electronic injection system performance precision components, resulting in dynamic performance degradation; sediment formation of coke in the intake valve, causing it to close lax, causing the engine idle speed is not stability, increased fuel consumption and emissions associated with deterioration; deposits will be hard coke in the piston crown and cylinder head and other parts of the formation, due to the high heat capacity and thermal conductivity of coke poor, prone to violent earthquakes and other engine failure; There will also be shortened TWC life. Work is good or bad injector on each engine power plays a fundamental role to play. Result due to poor fuel injector work not working, so that the cylinder coke serious; cylinder, piston ring wear accelerated, resulting in idle instability, increased fuel consumption, accelerate weakness, difficulty starting and emissions exceeded serious will completely clog spray glib, damage the engine. Therefore, regular cleaning fuel injectors, long periods of cleaning or frequent cleaning nozzles can cause a bad influence. As a matter of time cleaning, to be determined according to the quality condition and usually add fuel, in general, now most are recommended about 20,000 to 30,000 km for cleaning. Good condition, good quality fuel can be extended to about 4 to 60,000 km. When the nozzle slightly clogged, also have an impact on the condition. Sometimes such a failure: hang a block, start the car some jitter, etc. upshift during acceleration, this phenomenon disappeared, various sensors working assumption normal car, the throttle valve is also cleaned, the circuit is also normal it is likely that a slight blockage of the nozzle. But high gear acceleration, there may be mild gum has been sprayed away (dissolved), and vehicle performance resumed.
