Cross section view of engine speed sensor (7) Flywheel starter gear (8) Engine speed sensorEngine oil pressure is used to move the fuel rack. An electronically actuated rack solenoid (BTM) (2) controls a double acting hydraulic servo. The servo directs engine oil pressure to either side of a piston that is connected to the fuel rack. The oil pressure moves the piston. The piston moves the fuel rack.The servo is a rotor type oil pump. The servo increases the pressure of the engine oil that is supplied to the governor. The increased oil pressure allows a better regulation of engine speed during the rapid application or the removal of heavy loads on the engine.The rack solenoid (BTM) (2) is installed in the side of the rack actuator housing on the fuel injection pump. The rack solenoid (BTM) (2) is controlled by the ECM. The lever of the rack solenoid (BTM) is engaged in a collar on the rack servo valve. The rack solenoid (BTM) is spring loaded toward the position of fuel off. The solenoid must receive a positive voltage in order to move to the position of fuel on.Rack position sensor (5) is located inside the rack actuator housing. The rack position sensor is attached to the fuel rack by a magnet. The rack position sensor is a linear potentiometer that provides accurate feedback information for the ECM.In addition to the rack position data, the ECM receives data from other sensors that are located in the rack actuator housing. The engine speed sensor (8) is triggered by radial slots on the flywheel. Oil pressure, inlet air pressure, and the boost pressure sensors are mounted on the engine. These sensors are connected to the ECM. The ECM will limit engine speed and power output of the engine if low oil pressure occurs. When there is a change in boost and/or inlet air pressure, the control module adjusts the quantity of fuel or the timing of fuel that is delivered to the engine.The ECM operates shutoff solenoid (1). If the rack solenoid (BTM) (2) is unable to move the fuel rack to the position of fuel off, the shutoff solenoid will apply an additional force on the fuel rack in order to move the rack to the position of fuel off. A manual shutoff (6) (shutoff override shaft and lever assembly) is provided. The manual shutoff control shaft is spring loaded to a neutral position.If the shutoff solenoid fails to energize, the solenoid override may be used to move the shutoff lever away from the fuel rack servo (3). This will allow the rack solenoid (BTM) to move the fuel rack even though the shutoff solenoid is not energized.The manual shutoff may be used to shut down
