GENERAL INFORMATION



This Bosch® system was used on the ACC (1.8L) engine. Fuel is metered into the engine by monitoring engine speed and throttle position. The Engine Management System meters this fuel by firing the fuel injectors at a varying rate. Fuel volume is controlled by the duration of time the injector is left on. This "Injector Dwell Time" is usually measured in milliseconds of time.
