Abstract: A marine pump jet includes a rotor located upstream and in front of the rotor drive mechanism. The lower unit of the tractor pump jet has a rotor housing which substantially surrounds the rotor and a stator housing located downstream of the rotor and rotor housing. The drive shaft extending from the power head enters the stator hub where a pinion gear engages a crown gear attached to the rotor shaft. This places the rotor drive mechanism downstream of the rotor so that the rotor is substantially the first mechanical element that water initially comes into contact with. The inlet opening of the pump jet is larger than the outlet opening at the outlet of the stator housing. Because the rotor operates on essentially undisturbed, non-turbulent water, it is more efficient than traditional pump jets where the rotor is located aft of the drive mechanism. According to an alternative embodiment, a reverse shifting mechanism permits the tractor pump jet to operate in either the forward or reverse direction.

Abstract: A method of controlling fuel injection in an internal combustion engine including a crankshaft, a fuel injector, and a control unit for outputting a signal causing a fuel injection event, with a minimum time delay between the output of the signal and initiation of the fuel injection event, the method comprising the steps of sensing crankshaft position, outputting the signal, and providing an additional time delay between the output of the signal and initiation of the fuel injection event so that the signal must be output at an earlier crankshaft position than would be necessary without the additional time delay, whereby changing crankshaft speed has a greater effect on the difference between the desired crankshaft position of the fuel injection event and the actual crankshaft position of the fuel injection event.

Abstract: A variable integration based ignition circuit for an internal combustion engine recognizes predetermined engine conditions and modifies or limits ignition advance when the predetermined conditions are violated to protect the engine. The ignition circuit includes an ignition triggering circuit which causes the engine ignition to ignite in response to ignition pulse signals. A pulse generator generates and outputs signal pulses when the sensor detects positions of the crankshaft. A speed detector calculates the rotational speed of the flywheel based on the signal pulses. Ignition pulse signals are retarded when the rotational speed exceeds a predetermined level to limit rotational speed and protect the engine. The ignition circuit may also limit ignition pulse signals in response to low oil pressure.
