Resumen (Extraido del documento):
"Fundamentals of the Common Rail System"
10th Session: CONTROL SYSTEM SENSORS
In the last session, an outline explanation of the common rail system was given. In this session, the various sensors which input information to the engine ECU as electric/electronic data will be explained. The information sent to the engine ECU by each sensor is used to calculate the necessary command values for engine control.

1 FUNCTIONS OF EACH SENSOR
The function of each sensor is as per the following table. Sensor Name Crank Position Sensor (NE Sensor) Accelerator Position Sensor Intake Air Temperature Sensor Coolant Temperature Sensor Fuel Temperature Sensor Intake Air Pressure Sensor Atmospheric Pressure Sensor Airflow Meter Detects engine crank angle. Detects accelerator pedal angle. Detects intake air temperature before and after passing through the turbocharger. Detects engine coolant temperature. Detects CRS (Common Rail System) fuel temperature. Detects intake air pressure. Detects atmospheric air pressure. Detects air flow to the engine. Cylinder Recognition Sensor (TDC Sensor) Identifies engine cylinders. Function

Representative sensors from the chart above will be explained herein, from the crankshaft position sensor to the intake air pressure sensor
Intake Air Temperature Sensor

Intake Air Temperature Sensor Intake Air Temperature Sensor Airflow Meter Intake Air Pressure Sensor

Coolant Temperature Sensor Cylinder Recognition Sensor (TDC Sensor) Crankshaft Position Sensor (NE Sensor)

Accelerator Position Sensor

2 CRANKSHAFT POSITION SENSOR AND CYLINDER RECOGNITION SENSOR
Since signals from both sensors are used at the same time for the engine speed calculation and cylinder recognition, they will be explained together.

Crankshaft Position Sensor

The crankshaft position sensor is installed near the crankshaft timing gear or flywheel. This sensor is a MPU (magnetic pickup) type. When the pulsar gear installed on the crankshaft passes over the sensor, the magnetic
