3232853 - 1080B exhaust emission control system
The electronic control unit identifies the composition of the mixture (rich or lean) from the Lambda sensor output voltage.It adjusts the quantity of fuel injected to ensure the optimum composition of the mixture (l = 1) to create the ideal conditions for the treatment of the exhaust gases in the catalytic converter.If the mixture is too rich (lambda less than 1), then the quantity of fuel should be reduced and, if the mixture is too lean (lambda greater than 1), then the quantity of fuel should be increased.
