Basic Injection Amount

Operation

•  Fuel injection amount is controlled based on the fuel injector nozzle opening period.

Injection amount calculation

•  The PCM calculates the optimum fuel injection amount according to engine operation conditions.

•  The following two amount values are compared and the one of less amount is selected for the final injection amount.

Basic injection amount

•  The logically necessary injection amount is calculated based on the accelerator opening angle and engine speed.

Maximum injection amount

•  The maximum injection amount is calculated by correcting the basic injection amount based on driving conditions such as mass air flow, intake air temperature, and barometric pressure, intake air temperature and engine coolant temperature.
