Info

Engine Fuel signal from the ignition coil does not specify the timing for injection. It specifies the frequency of injections only, since the injection timing is always set to be constant. 2. Air flow system Intake air from the air cleaner is metered at the air flow meter, flows through the throttle chamber and into the intake manifold, and then flows through each intake manifold branch into the cylinder. Air flow during driving is controlled by the throttle valve located in the throttle chamber. During idling operation, the throttle valve is in the almost closed position, and the air is led through the bypass port mounted to the throttle chamber. In this case, the quantity of suction air is adjusted by means of the idle speed adjusting screw. During warming-<strong>up</strong> operation, the air flow is bypassed through the air regulator to increase engine rpm. EF-4
