Injector(S), Fuel: Description
High-pressure lines deliver diesel fuel under extreme pressure from the injection pump to the fuel injectors. This may be as high as 2000 bar (29, 008 psi). Use extreme caution when inspecting for high-pressure fuel leaks. Fuel under this amount of pressure can penetrate skin causing personal injury or death. Inspect for high-pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system.
Four electronically controlled fuel injectors (1) are located on top of the cylinder bank. The injectors generate a fine fuel atomization at injection pressures of up to 2, 000 bar (29, 008 psi). Each injector is held in place by a tensioning claw and retaining bolt. A copper seal washer (3) is located on the injector tip to seal off the injector to the combustion chamber. When servicing the injectors, always replace the copper seal ring and inspect the seal in the cylinder head cover. Lubricate the body of the injector with Mopar® 05012249AA - Nickel Antisieze Compound, or Molikote Anti-Fretting Paste (MB part number A001-989-42-51-10).
