Japanese Patent JP4440390
Kind Code:
B2
Abstract:
An outboard motor comprises an engine mounted within an engine compartment. The engine comprises an induction system having a throttle valve that controls the flow of air through the induction system. The engine also comprises a fuel injection system that controls the amount of fuel supplied to the engine. The amount of fuel injected into the engine is substantially reduced if the throttle valve rapidly close and a transmission of the outboard motor is engaged. If the transmission of the outboard motor is disengaged when the throttle valve rapidly closes, the amount of fuel injected into the engine is reduced to a lesser degree.
