Brief Description

Closed-loop fuel Injection system
- The catalytic converter has a high conversion ratio within a very narrow range. If the fuel-air mixture is not kept within this range, one or more gases will exceed permitted limits. A closed loop fuel injection system guarantees a correct fuel-air mixture. The level of oxygen is measured by an oxygen sensor that informs the Trionic or Motronic engine control module. The control module governs the fuel injection pulses so ensure the correct fuel-air mixture. See Closed loop fuel injection system.
