Magnetoelectric Sensor Of Pump System

Camshaft speed sensor  :

● determine TDC;

● it can be used as a backup function of crankshaft sensor.

Crankshaft speed sensor:

● determine engine speed and engine position;

● it can be used as a backup for camshaft sensor.

Camshaft sensor – provides top dead center position during starting; With the crankshaft sensor, it takes 15s to find the upper point position;

Pressure Sensor

  • Charge air pressure sensor of pump system
  • Avoid soot generation and limit injection at low boost pressure.
  • Oil pressure sensor (optional)
  • Monitor the oil pressure, protect the engine and stop at low oil pressure.
  • Atmospheric pressure sensor
  • Protect supercharger – when driving on high altitude, the engine can be protected by reducing engine power.
  • temperature sensor
  • Boost temperature sensor
  • Sensing air volume, determining air density, optimizing injection volume and injection timing.
  • Fuel temperature sensor
  • Used for correction of injection quantity.
  • Coolant temperature sensor
  • Protect the engine when the engine temperature is too high, and optimize the injection quantity and injection timing when the cold start and ambient temperature are too low.

Position Sensor

Pedal travel position sensor 

Transfer the driver’s expectation of vehicle acceleration to the control unit (ECU)
