Petrol Fuel System

View Comments

On some petrol fuel systems, the fuel system is monitored and controlled by the ECU (Electronic Control Unit). The Electronic Control Unit is controlled by the data input from a set of sensors located all over the engine and its ancillaries. The sensors detect various operating states of the engine, and the performance desired. The sensors constantly monitor:

  1. Ambient Temperature
  2. Exhaust Manifold Temperature
  3. Throttle Position
  4. Engine RPM
  5. Inlet Manifold Vacuum
  6. Exhaust O2 content

Once the ECU receives all of the data inputted form the above sensors it can give commands to the engines ‘Fuel Intake System’, and ‘Spark Ignition Timing System’. This will deliver an overall satisfactory performance from ‘switch on’, to ‘switch off’.
