Fuel Injection Control

Injection pattern 

ECM conducts sequential injection (1 injection per 2 rotations of engine to each cylinder, suitable injection according to each cylinder's ignition order).

Injection when starting the engine 

When starting the engine, ECM determines the amount of fuel injected according to conditions such as engine coolant temperature to make the starting smoother.

Also, conducts the starting control with stratified-charge combustion according to conditions.

Injection when driving normally 

Normally, ECM determines the amount of injection to be an optimum air-fuel mixture ratio for homogeneous combustion.

Cut-in injection when acceleration 

When accelerating, according to the opening speed of throttle valve, ECM conducts a cut-in injection adding to normal injection and improves accelerating performance.
