Abstract: An engine starting system is provided which is used with a vehicle equipped with a gear driving starter which is energized to bring a pinion gear into engagement with a ring gear of an engine mounted in the vehicle and also to rotate the pinion gear to crank the engine. The engine starting system works to terminate energization of the starter after the starter is energized to start the engine. The engine starting system executes combustion control to control combustion of fuel in the engine so as to develop a first firing event where the fuel is first fired in the engine after the energization of the starter is terminated. This minimizes the gear noise when the engine is being cranked and ensures the stability in starting the engine.
