FUEL INJECTION CONTROL OPERATION [L3]

BME014000140T32

## Injection Timing

### Synchronized injection

  • PCM determines fuel injection timing and amount synchronized with the crank angle, and based on the following signals during the intake/exhaust stroke of each cylinder.
  - CKP, MAF, ECT, IAT

### Non-synchronized injection

  • PCM determines fuel injection timing and amount based on the following signals (not synchronized with the crank angle).
  - TP, MAF, ECT, IAT

## Correction

BARO correction
• Purpose: to maintain the engine stability
• Conditions: at all time
• Action: lower BARO, larger correction
Rear HO2S feedback correction
• Purpose: to control air/fuel ratio close to increase the performance of the catalytic converter
• Conditions: at feedback zone
• Action: Rear HO2S output voltage
