• The fuel injector is controlled by an extremely precise piezo electric actuator that can accomplish multiple injections per combustion event. NOTE: Never unplug a fuel injector while the engine is running, serious engine damage could occur!
• The glow plug is used to heat the air in the cylinder. • The glow plug utilizes a system of sending voltage through a resistance coil to create heat. NOTE: The 6.4L glow plug is very similar to the glow plug used on the 6.0L Power Stroke® Diesel, but they are different. The glow… Read More »
• The GPCM is a unit that controls the glow plugs in order to warm the air in the cylinders. • The GPCM uses a glow plug enable signal to turn the glow plugs on for a time controlled by the ECM. • The GPCM is capable of diagnosing a problem with one glow plug… Read More »
• The glow plug system is used to warm the air in the cylinders to enhance cold weather startability and reduce start up smoke. • The glow plug system is ECM controlled, and powered by the GPCM.
• The ECM, which is mounted behind the engine on the passenger side cowl, uses sensor inputs to control actuators and send fueling commands to the fuel inectors. • The ECM controls the fuel and air management system on the 6.4L Power Stroke® Diesel.
• The throttle body is operated by a stepper motor controlled by the ECM and assists with the exhaust aftertreatment system.
• The turbocharger actuator is an electronic motor that controls the position of the vanes inside of the high pressure turbocharger’s turbine housing. • The turbocharger actuator is mounted directly to the high pressure turbo and is connected to the vanes inside the turbine housing by a control arm.
• The EGR valve is used to mix cooled exhaust gases with intake air to lower emissions and noise. • The EGR valve is stepper motor controlled • The valve is powered in both the open and close directions.
• The VCV regulates the delivery of fuel from the internal transfer pump (ITP) to the high pressure pumping elements. • The VCV adjusts the low pressure side of the system to match the needs of the engine thus increasing efficiency. • The VCV is permanently mounted… Read More »
• The PCV governs the fuel pressure that is delivered to the fuel injectors via the high pressure fuel rails and fuel supply tubes. • The PCV also acts as a dampening device for the fluctuations in pressure that occur during fuel delivery through the pump… Read More »
