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 injector supplying fuel to the combustion chamber, the fuel injector including an actuator to regulate an amount of fuel injected by the fuel injector, a valve mechanism configured to regulate fluid flow into and out of the combustion chamber, the valve mechanism including at least one camshaft coupled to the output shaft and arranged to actuate at least some valves of the valve mechanism, and a fuel control system including a controller, which is connected to the fuel injector actuator, a first sensor, which is arranged to detect rotation of the output shaft, and a second sensor connected to the controller and positioned to sense rotation of the camshaft, the first sensor being adapted to produce a first signal that is indicative of rotation of the output shaft and being connected to the controller, the second sensor being adapted to produce a second signal at the beginning of an intake stroke of the second member, the controller being configured to output a control signal to actuate the fuel injector actuator when the first signal is received from the first sensor indicating that the output shaft has initially begun to rotate and when the second signal is received from the second sensor indicating that the second member is starting an intake stroke.
