Abstract: A piston for a direct fuel injection engine is described. The piston comprises a cylindrical skirt and a piston face. The cylindrical skirt has an axis. The piston face has a bowl. The bowl has a wall extending about an axis in inclined relation to the cylindrical skirt axis. An engine is also described. The engine comprises an engine block defining an engine cylinder and a piston moveable axially in the engine cylinder. The piston comprises a cylindrical skirt and a dome-shaped piston face, the piston face having therein a bowl. The bowl located with the cylinder axis passing therethrough. The bowl is defined by a cylindrical wall extending about an axis extending in inclined relation to the axis of the cylinder. The bowl includes a bottom wall extending perpendicularly to the bowl axis. The engine also comprises a fuel injector nozzle adapted to direct a spray of fuel toward the bowl for deflection toward a spark plug disposed on the opposite side of the cylinder axis from the fuel injector.

Abstract: A method of operating a two-stroke, spark-ignited, internal combustion engine in which the ignition is time-based controlled at low or idle speeds and is crank-angle-based controlled at higher speeds.

Abstract: Disclosed herein is an outboard motor including a propulsion unit including an internal combustion engine having an exhaust port and an exhaust gas discharge system including a catalytic converter comprising a housing having an outer wall defining an axis, an inlet end with an inlet, and an outlet end with an outlet, a catalytic element located in the housing concentrically with the axis and having an outer surface defining, with the housing outer wall, an outlet volume which increases in size in the direction toward the housing outlet end, an inner surface spaced from the outer surface, defining therein an inlet volume, and defining, adjacent the housing outlet end, a by-pass opening communicating between the inlet volume and the housing outlet, and flow passages extending radially outwardly from the inner surface to the outer surface, communicating, at the inner surface, with the inlet volume, and communicating, at the outer surface, with the outlet volume, and a deflector moveable between a blocking positi

Abstract: Disclosed herein is a fuel pump comprising a housing including therein a high pressure fuel chamber, a fuel outlet valve communicating with the high pressure fuel chamber and being operable to prevent fuel inflow and to permit fuel outflow when the fuel pressure is above a predetermined level, a fuel inlet valve communicating with the high pressure chamber and being operable to prevent fuel outflow and to permit fuel inflow, and a bearing bore extending from the high pressure chamber, a rod slideably and sealingly supported in the bearing bore for movement relative to a retracted position, and structure located in the housing for displacing the rod from the retracted position and in the direction toward the high pressure fuel chamber through an initial stroke length without encountering substantial resistance and thereafter displacing the rod through a subsequent stroke length which is effective to highly pressurize the fuel in the high pressure fuel chamber.

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: Disclosed herein is a valve construction comprising a main body having therein a bore extending along an axis, adapted to contain fuel under pressure, and having, at the axially outer end thereof, an axially outwardly diverging conical surface extending at a first acute angle to the axis, and a needle valve located in the axial bore, movable relative to the main body between open and closed positions, and including a stem portion, and a head portion including a first diverging conical surface which extends axially outwardly from the stem portion at a second acute angle greater than the first acute angle and terminates in a first edge which, when the needle valve is in the closed position, sealingly engages the conical surface of the main body, and which has a diameter, a second surface which extends axially outwardly from the first edge in increasingly spaced relation from the conical surface of the main body and then in decreasingly spaced relation from the conical surface of the main body and which terminat
