3) Injection Volume Control
(1) Overview
To keep the best engine conditions and to reduce the emission gas, ECU determines the injection
volume and timing.

4) Ignition System Control
(1) Overview
G20DF engine is equipped with the single ignition system. Each spark plug is operated independently
by the ECU and one ignition coil and spark plug are provided for each cylinder.

(4) Features
Determines the ignition timing according to input signal
The ECU always analyzes the following elements when determining the ignition timing. 1.
Crankshaft position sensor
Camshaft position sensor
Coolant temperature sensor
Intake air temperature/air mass -
-
-
-
Warm-up of catalytic converter
The ignition timing is retarded for about 20 seconds to operate the catalytic converter according to the
operating temperature under the following conditions: 2.
The idle speed is increased by the idle speed control to help warming up of the catalytic converter -
-
Idle speed control
The ignition timing control can be performed faster than the control through the throttle valve.
Fuel cut-off in deceleration
The ignition timing is retarded temporarily to prevent abrupt increase of the torque when the
combustion is restarted.
Intake air temperature/coolant temperature
The ignition timing is retarded to prevent knocking if the intake air temperature or coolant temperature
is high. The ignition timing is retarded in the following cases. 3.
4.
5.
-
-
The ignition timing retard for intake air temperature and for coolant temperature is added up for
correction.
ESP/ASR control mode
The ignition timing is retarded to reduce engine torque as fast as possible under the ESP/ASR
control mode.
Knocking control
If knocking occurs in the cylinder, the ignition angle of the corresponding cylinder is retarded. The
