ABSTRACT:
The present invention involves a fuel injection system for an internal combustion engine for small utility implements. The engine includes a crankcase with a cylinder bore. The crankcase rotatably supports a crankshaft having a flywheel and a magnet disposed on an outer periphery of the flywheel. The crankshaft is also connected to a reciprocating piston disposed in the cylinder bore. A cylinder head is attached to the crankcase over the cylinder bore, and a fuel injector is disposed in the cylinder head. The fuel injector is in communication with a fuel supply and can inject quantities of fuel into the cylinder head. An induction coil is disposed adjacent to the flywheel, and is coupled to the fuel injector so that rotation of the flywheel generates a pulse on the induction coil that actuates the fuel injector. A fuel pump is driven by the crankshaft and supplies pressurized fuel to the injector. A timing control circuit is connected to the fuel injector and the induction coil to regulate the operation of the fuel injector. The timing control circuit interrupts the induction coil with a pulse width modulated signal when the duration of the actuating pulse exceeds a calculated duration to close the fuel injector. A pressure sensor is disposed in the cylinder head and provides an input to the timing control circuit.
