Air Fuel Ratio (A/F) Sensor Heater Control
Outline
Based on the control of the A/F sensor heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
...
Fuel Injection Control System
Outline
Performs optimum fuel injection according to engine operation conditions.
The PCM determines the engine operation conditions based on the signals from
each input device and drives the fuel injectors at the optimal fuel injection
time (fuel injection amount) and the fuel ...
