Abstract:
An internal combustion engine comprising an engine body assembly defining at least one cylinder closed at one end, at least one piston reciprocating within the cylinder, at least one combustion chamber formed within the engine body assembly by the cylinder, the closed end of the cylinder and the piston, the piston having a head that faces the closed end of the cylinder, the piston being coupled to an output shaft such that movement of the reciprocating movement of the piston causes the output shaft to rotate, a fuel injector arranged to supply fuel to the combustion chamber, the fuel injector including an actuator to control a flow of fuel through the fuel injector, and a fuel control system coupled to the actuator and configured to control the actuator so as to not inject fuel into the combustion chamber when the output shaft is within prohibited shaft angle range that is located past a top-dead-center position, the fuel control system is also configured to control the fuel injector to inject fuel into the combustion chamber after the prohibited shaft angle range when the engine is operating under a first load condition and to inject fuel into the combustion chamber before and after the prohibited shaft angle range under a second load condition, the second load condition being greater than the first load condition.
