Fuel Injection Control System
FUEL INJECTION CONTROL
In this system, the ECM controls the "ON" time (length of pulse) and timing of the fuel injection from the fuel injector into the cylinder head
intake port according to the signals from the various sensors so that a suitable air/fuel mixture is supplied to the engine in each driving condition.
FUEL INJECTION TIMING
There are two types of injection timing. One is "Synchronous Injection" in which injection is synchronous with the ignition signal (or signal from
Camshaft Position [CMP] sensor) and the other is "Asynchronous Injection" in which injection takes place independently of the ignition signal (or
signal from Camshaft Position sensor).
The factors to determine the injection time are the basic injection time which is calculated on the basis of the engine speed and the amount of the
intake air and various compensations which are determined according to the signals from various sensors that detect the state of the engine and
driving conditions.
