The engine ECM operates each kind of control based on the signals from each type of sensor. The actuator for controlling the amount, timing, and mixture of fuel injection is the injector, while the actuator for controlling fuel pressure is the supply pump.Fuel Quantity Control
The amount of fuel to be injected is determined using a basic injection amount, which is calculated based on the state of the engine and driving conditions, with corrections added for parameters such as water temperature, fuel temperature, intake air temperature, intake pressure.Injection Timing Control
The ECM controls the timing for starting to energize the injectors, first determining the timing for the main injection and then setting the timing of other injections, such as pilot injections.Fuel Mixture Control
By conducting a pilot injection, the initial fuel mixture is kept to a minimum, mitigating the explosive initial combustion and reducing NOx and noise.Fuel Pressure Control
The ECM calculates the set fuel injection pressure based on the engine load (last injection amount and engine RPM) and controls the amount the supply pump supplies and the fuel pressure inside the rail.Sensors
Crankshaft Position Sensor
Illustration 3 g02900557
(1) Gear Case
(2) Crankshaft Position Sensor The crankshaft position sensor is mounted near the crankshaft gear of the gear case (1) and the sensor utilizes an MRE (magnetic resistance element) type of sensor.
Illustration 4 g02930437When the crankshaft pulser gear passes by the sensor, it alters the magnetic field inside the sensor, generating an AC voltage, which is output to the engine ECM.The gear has a wide part between teeth, which alters the waveform of the AC voltage and the sensor detects the crankshaft position with every revolution.The engine ECM uses the signals to calculate the piston position and engine RPM.Camshaft Position Sensor
Illustration 5 g02900917
(3) Camshaft Position Sensor The camshaft position sensor is mounted near the camshaft gear and the sensor functions in the same way as the crankshaft position sensor.
Illustration 6 g02930596
(4) Camshaft Pulser Gear This sensor detects the extra teeth (two teeth) of the camshaft pulser gear and the engine ECM uses the signal to calculate the piston position.Intake Air Temperature Sensor
The intake air temperature sensor measures the intake temperature after the air passes through the turbocharger.Coolant Temperature Sensor
The coolant temperature sensor is mounted on the cylinder head and detects the temperature of the coolant.Fuel Temperature Sensor
The fuel temperature sensor is mounted on the fuel intake side of the supply pump and detects the temperature of the fuel.Intake Air Pressure Sensor
The intake air pressure sensor is a semiconductor pressure sensor and when there are changes in the pressure on the silicon element inside the sensor.The intake air pressure sensor measures the intake air pressure after the air passes through the turbocharger.Barometric Pressure Sensor
The barometric pressure sensor is located on the back of the ECM.
