Sprinter 2500 V6-3.0L DSL Turbo (2008)
Fuel Injector: Description and Operation
Fuel Injector - Description
DESCRIPTION
Three electronically controlled fuel injectors are located on top of each cylinder bank. The injectors generate a fine fuel atomization at injection
pressures of up to 1,600 bar (23,200 psi). Each injector is held in place by a tensioning claw and retaining torque-to-yield bolt. A copper seal ring 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
retaining torque-to-yield bolt. Lubricate the body of the injector with Mopar(R) 05012249AA - Nickel Antiseize Compound, or Molykote Anti-Fretting
Paste (MB part number A001-989-42-51-10).
WARNING: High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This may be as high as 1600
bar (23,200 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 high-pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective
clothing when servicing the fuel system.
