1 - 20GENINFOFEATURESFuel control during normal drivingIn synchronous injection during normal driving, fuel is injected on a cylinder-by-cylinder basis whenall of the conditions below are met:1 Other than the stop mode2 Cylinder identification completed3 Other than overrunTo determine the injection timing, the ECU calculates the injection timing through the use of the 3Dcontrol map provided in the ECU, which is based on the throttle position and the engine speed.The injection duration is based on the basic injection duration (obtained through the throttle position,intake air pressure, and engine speed) to which injection duration compensation (based on the sig-nals from various sensors such as the intake temperature sensor, atmospheric pressure sensor,and O 2 sensor) is added to determine the final injection duration. As a result, fuel is supplied to thecylinders.• Normal synchronous injection1 Injector #12 Injector #23 Injector #34 Injector #4È Cylinder identificationsignalÉ Crankshaft identifica-tion signalÊ InjectionË Stop• Fuel injection control during normal drivingÈ #1 cylinder fuel injec-tion timingÉ Basic injection dura-tionÊ Various types of fuelinjection duration com-pensationsË Synchronous injectionduration (final injec-tion duration)#2 #4 #3 #1 #2 #4 #3 #1
