Mechanical cr injector nozzle works by controlling precision couplings (needle valve, needle valve body). The coupling of the nozzle is one of the three precision (Three precision coupling parts include plunger, plunger sleeve, needle valve, needle valve body, oil outlet valve, oil outlet valve seat) couplings of the traditional diesel engine.
Normally, The injector nozzle itself is a closed valve, The opening and closing of the valve is controlled by a valve needle moving up and down. When the ECU issues a fuel injection command, its voltage signal will cause current to flow through the coil in the fuel injector nozzle, generating a magnetic field to attract the valve needle, allowing the valve to open so that fuel can be sprayed out from the fuel injection hole.
The biggest advantage of injection fuel supply is that the control of fuel supply is very precise, so that the engine can have the correct air-fuel ratio in any state, not only to keep the engine running smoothly, but also the exhaust gas can meet the environmental protection regulations.
Cause to Damage of CRInjector Nozzle
(1) CR injector nozzle failure caused by impurities (water, lead, aluminum powder, iron powder, sulfide) in fuel exceeding standard requirements.
(2) The nozzle is normally worn due to long time working under high temperature
(3) Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector can not work properly.
(4) Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector can not work properly.
(5) The wear of the nozzle nozzle leads to the increase of fuel quantity, resulting in black smoke of the vehicle, and the fuel injector can not work properly when it is serious.
(6) If the nozzle needle can not move smoothly stuck may cause serious damage to the injector nozzle.
(7) The rusting of the nozzle spring leads to spring fracture and black smoke from the vehicle.
(8) The opening pressure of the nozzle decreases, and the oil quantity of the injector increases, leading to black smoke of the vehicle, and the injector can't work properly when it is serious.
(9) Oil-nozzle needle valve lift adjustment gasket wear oil-nozzle needle valve stroke becomes larger, the fuel injector oil quantity becomes larger, resulting in black smoke of vehicles, resulting in the fuel injector can not work properly when serious.
(10) The cracking of the nozzle cap is caused by high intensity work under high temperature.
