BASE GP-VALVE COVER & INJ HARN 2785662 - Caterpillar

is the method of programming or updating an ECM with an electronic service tool over the data link instead of replacing components.Fuel Injector E-Trim - Fuel injector E-trim is a software process that allows precise control of fuel injectors by parameters that are programmed into the ECM for each fuel injector. With the use of the electronic service tool, the service technician can read status information for the E-Trim. Data for E-Trim can also be programmed.FRC - See "Fuel Ratio Control".Fuel Pump - See "Fuel Rail Pump".Fuel Rail - This item is sometimes referred to as the High Pressure Fuel Rail. The fuel rail supplies fuel to the electronic unit injectors. The fuel rail pump and the fuel rail pressure sensor work with the ECM in order to maintain the desired fuel pressure in the fuel rail. This pressure is determined by calibration of the engine in order to enable the engine to meet emissions and performance requirements.Fuel Rail Pressure Sensor - The fuel rail pressure sensor sends an electronic signal to the ECM that is dependent on the pressure of the fuel in the fuel rail.Fuel Rail Pump - This item is sometimes referred to as the High Pressure Fuel Rail Pump. This is a device that supplies fuel under pressure to the fuel rail (high pressure fuel rail).Fuel Rail Pump Solenoid Valve - This is sometimes referred to as the High Pressure Fuel Rail Pump Solenoid Valve. This is a control device in the high pressure fuel rail pump. The ECM controls the pressure in the fuel rail by using this valve to divert excess fuel from the pump to the fuel tank.Fuel Ratio Control (FRC) - The FRC is a limit that is based on the control of the ratio of the fuel to air. The FRC is used for purposes of emission control. When the ECM senses a higher intake manifold air pressure (more air into the cylinder), the FRC increases the FRC Limit (more fuel into the cylinder).Full Load Setting (FLS) - The FLS is the number that represents the fuel system adjustment. This adjustment is made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. This parameter must be programmed.Glow Plug - The glow plug is an optional starting aid for cold conditions. One glow plug is installed in each combustion chamber in order to improve the ability of the engine to start. The control panel uses an internal timer to determine when the glow plug relay must provide power to each glow plug. Each of the glow plugs then provides a very hot surface in the combustion chamber in order to vaporize the mixture of air and fuel. This improves ignition during the compression stroke of the cylinder.Glow Plug Relay - The glow plug relay is controlled by the control panel in order to provide high current to the glow plugs that are used in
