FUEL INJECTION TIMING CONTROL OPERATION [MZR-CD 2.2]
id0140f2186200
• Fuel injection start timing is determined based on the fuel injection amount and crank angle signals input from the crankshaft position sensor.
Determination of Fuel Injection Timing
• The PCM calculates the optimum fuel injection timing based on the predetermined target fuel injection timing and input signals from each sensor.
Target Fuel Injection Timing
• Target fuel injection timing is calculated based on engine speed and fuel injection amount.
Injection Timing Correction
• Actual fuel injection timing is corrected based on the input signals from each sensor such as intake air temperature, engine coolant temperature, and barometric pressure.
