Explain how the computer controls the air-fuel ratio on an EFI system.

To determine

The control of the air-fuel ratio on an EFI system by the computer system.

Explanation

The main objective of computer controlled EFI (electronic fuel injection) systems is to provide the system with the stoichiometric ratio (i.e. the ideal air-fuel ratio) which is required for total combustion of the fuel. Although the ideal air-fuel ratio is impossible to achieve, almost ideal conditions may be attained to reduce emissions from incomplete combustion of fuel...
