2. 1933613 XPI Injector Technical Support
2.1. 1933613 XPI Injector Installation Precautions
(1) The replacement of the XPI injector must strictly follow the electrical system, the approved pressure of the low-pressure fuel intake system, the approved pressure of the high-pressure fuel circuit system, and fuel system replacement consumables requirements (including the low-pressure fuel circuit system filter and the high-pressure fuel circuit) specified in the vehicle engine maintenance manual.
(2) Strictly follow the operation manual of replacement of wearing parts of the fuel system, cleaning requirements for the connection between the fuel system and the XPI injector, the fitting clearance of the XPI Injector connection, the installation angle and tightening torque of the XPI injector, the fitting clearance of the intake system, and the fitting clearance of the exhaust system, so that to ensure the service life of the engine and the normal operation of the XPI injector.
(3) When installing the XPI injector on the engine, it is necessary to clean the engine block, cylinder head and other parts connected to the XPI injector, and ensure that there is no dust, carbon deposits, water, rust spots,
(4) Before installing, check whether the XPI injector nozzle gasket has been replaced and installed on the XPI injector.
(5) When installing the XPI injector, apply lubricant between the XPI injector, XPI injector nozzle sealing gasket and O-ring.
(6) If a new gasket is not replaced, it can lead to: deformation of the tight cap of nozzle, deformation of nozzle, deformation of nozzle orifice, oil leakage and air leakage, which will cause serious damage to the XPI injector and nozzle to break and cause damage to the engine.
(7) When installing the XPI injector on the engine, please carefully check the components related to the installation of the XPI injector to ensure they are not deformed, such as the XPI injector pressure plate, screw, XPI injector rod and other accessories, and install it in strict accordance with the operation steps of the engine maintenance manual.
(8) It is forbidden to operate the bare XPI injector for a long time in an environment with serious dust pollution and corrosion to iron products.
(9) It is forbidden to operate the bare XPI injector for a long time in a strong magnetic field environment.
2.2. 1933613 XPI Injector Reasons for Not Working Normally
(1) There is air in the oil circuit of the engine fuel system.
(2) Vehicle fuel XPI injector fuel supply system is abnormal.
(3) Engine common rail system oil leakage or pressure limiting valve damage.
(4) There is a short circuit, cutting out and poor contact in the wiring harness connected to the XPI injector of the vehicle.
(5) The long-term placement of the XPI injector causes the anti-rust oil to solidify, and the internal components are stuck or the oil holes are blocked.
Before installing, carefully check whether other components in the common rail system except the XPI Injector are damaged to prevent the XPI Injector from not working properly after being replaced.
