Engine Operation 32 UENR0623-02 (16) Engine exhaust gas temperature sensor (17) Crankshaft speed/timing sensor (18) Camshaft speed/timing sensor (19) Electronic unit injectors (20) Fuel injection pump (21) Fuel pressure sensor (22) Oil pressure switch (23) Coolant temperature sensor (24) ECM (25) Engine (26) Glow plugs (27) Glow plug Control Unit (GCU) (28) Primary fuel filter with water-in-fuel sensor (29) Inlet manifold air temperature/pressure sensor (30) Secondary fuel filter with fuel temperature sensor (31) Fuel tank Note: A separate intake manifold air pressure sensor and intake manifold temperature sensor are installed on the 55 kW (74 hp) engine. Note:
The ECM is not mounted on the engine. The electronic control system has the following components: ECM Pressure sensor Temperature sensors Crankshaft speed/timing sensor Camshaft speed/timing sensor The suction control valve for the fuel injection pump Wastegate solenoid Electronic unit injectors Sensor Locations for the Engine The illustrations in this section show the typical locations of the sensors for the industrial engine. Specific engines may appear different from the illustration due to differences in applications.
