Abstract:
An internal combustion engine comprising at least one combustion chamber formed by at least a first member and a second member that moves relative to the first member, the second member being coupled to an output shaft such that movement of the second member causes the output shaft to rotate, a fuel injection system including a fuel injector that supplies fuel to the combustion chamber and a fuel pump that supplies fuel to the fuel injector, the fuel injector including an actuator to regulate an amount of fuel injected by the fuel injector, a main switch having an on position and an off position, and a fuel control system including a controller, which is operatively connected to the actuator, and a sensor, which is arranged to detect rotation of the output shaft, the sensor being adapted to produce a signal that is indicative of rotation of the output shaft and being operatively connected to the controller, the controller being configured such that, when the engine is operating and the main switch is turned from the on position to the off position, the controller outputs a control signal to the actuator so that fuel is no longer injected through the fuel injector and after a specified time the controller outputs a control signal to the actuator to inject a second amount of fuel when the sensor indicates that the output shaft is rotating below a specified speed.
