Abstract: An outboard motor comprises an engine mounted within an engine compartment. The engine comprises an induction system having an induction passage extending between an air intake box to a combustion chamber. A throttle valve is positioned along the passage. A bypass passage communicates with the passage at a location between the throttle valve and the combustion chamber. An adjustable valve controls flow through the bypass passage. The adjustable valve is opened as the throttle valve is opened or as the engine speed is increased. The adjustable valve is closed when the throttle valve is rapidly closed or when the engine speed is rapidly decreased.

Abstract: A nozzle (7) for a nitrous oxide system for an internal combustion engine contains outlet (9), to produce a high velocity cylindrical stream of nitrous oxide (9′) expressed in a certain direction (29) and another outlet (11), located on the same side of the nozzle, such as a slot, to produce a thin fan shaped mist of fuel (11′) expressed in a second direction (31) from another location with the directions being inclined at an acute angle (&agr;) relative to one another, preferably forty-five degrees. The spray of fuel and stream of nitrous oxide collide at a location (D1, 18) displaced from the side of the nozzle, wherein the high velocity stream of nitrous oxide further atomizes the fuel and mixes therewith as injected into the intake of the engine.

Abstract: An improved method of identifying the cylinder combustion sequence of a four-stroke internal combustion engine accepts of rejects an assumed combustion sequence based on measured ion current combustion quality (CQ) indications. Individual CQ indications for the various engine cylinders are algebraically combined as a function of the assumed combustion sequence so that the combined CQ indication increases in a first polarity if the assumed combustion sequence is correct, and in a second polarity if the assumed combustion sequence is incorrect. When the absolute value of the combined CQ indication exceeds a threshold, the polarity of the combined CQ indication is used to either accept or reject the assumed combustion sequence.

Abstract: An internal combustion engine control unit for hybrid vehicle makes an electric motor function as a main driving source for the vehicle under a predetermined condition and at the same time, controls a hybrid mechanism so as to warm up the internal combustion engine. If a requested engine output to the internal combustion engine exceeds a predetermined output or if an accelerator opening degree exceeds a predetermined opening degree, the same control unit changes the operating condition of the internal combustion engine from the warm-up operation condition to an operation condition fitting to the requested engine output.

Abstract: The invention relates to a method for energising a coil for driving a moving contactor core of an electric starter for a motor vehicle, in which the effective current is varied in the coil during displacement of the core to its contact position, and in which, in the course of this displacement, there take place: a first driving phase with an effective current which is high enough to set the core in motion, and then a second driving phase with a smaller effective current, in which, after a determined or predetermined time, the effective current is continuously increased.

Abstract: Disclosed is a two way valve that has a valve chamber having a first valve chamber opening bounded and a fluid flow opening. A chamber shuttle, adapted to travel within the valve chamber, is characterized by a chamber shuttle cavity and has a first chamber shuttle cavity opening and a second chamber shuttle cavity opening. A shuttle-plug that is biased by a force established within the valve closes the chamber shuttle cavity to establish a closed fluid-flow state. The chamber shuttle is also movable against the biasing force thereby resisting the shuttle-plug by a structure fixed relative to the valve chamber and opening the chamber shuttle cavity to establish a second fluid-flow state. A preferred embodiment of the invention is incorporated in a valve construction of components that incorporate aspects of the disclosed invention.

The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism.

Abstract: The present invention is directed to a textured bone allograft for implantation in a patient, having one or more textured bone surfaces, and methods of making and using the textured bone graft. The textured surface preferably includes a plurality of closely spaced discrete, continuous, or a combination thereof, protrusions. The textured bone allograft is useful for repairing bone defects caused by congenital anomaly, disease, or trauma, in a patient, for example, for restoring vertical support of the anterior column. Implantation of the textured bone allograft results in improved graft stability and osteoinductivity, without a decrease in mechanical strength. The textured bone allograft does not shift, extrude or rotate, after implantation.
