International Classification:

F02M 5100

US Classification:

701115, 73119 A, 123486

Abstract:

State-of-the-art fuel injectors can be defined by a third-order polynomial to define their performance curve and to optimize performance of the fuel injected engine. Such systems are preprogrammed to use a set of fixed coefficients when replacing fuel injectors. Therefore, these replacement fuel injectors must be manufactured with very precise tolerances so as to operate efficiently with these fixed coefficients. The present invention includes a method and apparatus that allows the use of production fuel injectors that are more economical since they can be manufactured with wider tolerances. The production fuel injectors are supplied with a computer program and a data file having a set of replacement coefficients that are determined especially for that particular fuel injector. The approach allows the restoration of the existing coefficients if the replacement fuel injector does not solve the service problem experienced by the user of the fuel injected engine. The new, replacement fuel injector, together with its specific coefficients, can then be used in another application.

Bombardier Motor Corporation of America - Grant FL

International Classification:

F02B 1700

US Classification:

123295, 123 73 C, 123305

Abstract:

A control unit is provided for an internal combustion engine including an engine block comprising a plurality of cylinders operable in a homogenous combustion mode and a stratified combustion mode in response to an engine throttle position. The control unit is programmed to switch the engine cylinders to the homogenous combustion mode at a throttle position of greater than about 20% of wide open throttle. As such, the combustion mode is switched form the stratified combustion mode to the homogenous combustion mode at a higher throttle opening that more capably supports increased fuel injection quantities of homogenous combustion in the engine cylinders. Problematic conditions of conventional pontoon boat systems due to switching of engine cylinders to homogenous combustion at high RPMs and restricted throttle openings is therefore avoided.

International Classification:

G01M 1900

US Classification:

731181

Abstract:

The present invention, in one aspect, includes a diaphragm assembly for being connected between an engine exhaust path and an engine electronic control unit to transmit changes in exhaust gas pressure from the exhaust path to the control unit. In an exemplary embodiment, the diaphragm assembly includes a diaphragm housing and a diaphragm positioned in the housing and separating a first chamber and a second chamber. The first chamber is configured to be in flow communication with the exhaust path and the second chamber is configured to be in flow communication with the engine control unit. The diaphragm housing, in the exemplary embodiment, includes a first housing member and a second housing member. An inner surface of the first housing member also is a side wall of the first chamber, and the inner surface has a conical shape to facilitate drainage of water from the first chamber. Also, the first chamber has a first volume and said second chamber has a second volume.

International Classification:

F02D 31/00

US Classification:

123376, 123400

Abstract:

An apparatus and method for adjusting a throttle plate of a throttle assembly of an internal combustion engine is disclosed. A throttle linkage mechanically connects a throttle actuator to the throttle assembly with a deadband therebetween. The deadband allows the throttle plate to remain in a closed position during initial movement of the throttle actuator and initial acceleration, thereby reducing overall engine noise.

US Classification:

440 89

Abstract:

The present invention, in one aspect, includes a probe for sensing exhaust gas pressure in an exhaust path of a marine engine during engine operation. In an exemplary embodiment, the probe includes an elongate probe body and an engine engagement assembly secured to the probe body and configured to engage to the engine so that said probe body at least partially extends into the engine exhaust path. The probe body comprises a hollow, cylindrical shaped member, and at least one opening extends through a side wall of the cylindrical shaped member. A cap is secured to and closes an open end of the probe cylindrical shaped member, and a pellet is located, i. e. , trapped, within the cylindrical shaped member. The engine engagement assembly includes a threaded portion sized to be threadedly engaged within an opening in flow communication with the engine exhaust path, and a tube connection portion sized to be inserted within a tube.

A61F 5/441

Abstract:

An ostomy appliance () includes a pouch wall () defining at least a portion of a collection chamber () configured to collect and store effluent from a stoma, an inlet () formed in the pouch wall configured to be positioned adjacent to the stoma, and a filter assembly () connected to the pouch wall. The filter assembly includes a base (), a carrier (), and at least one filter (). The base includes a vent opening (118) disposed in fluid communication with the collection chamber, the carrier is movably connected to the base, and the at least one filter retained in the carrier. The carrier is operable to move the at least one filter relative to the vent opening to clean the filter by way of contact between the base and filter during movement of the filter relative to the base. An stomy appliance including a slidable filter assembly for cleaning a filter is also provided.

Abstract:

A device for holding an endotracheal tube has a slide track configured to fit adjacent a lip on a patient's face. The track has a face contacting side, an exposed side, and a pair of opposite ends. A tube holder is coupled to and slidable along the track. A positioning mechanism is releasably lockable to allow selective lateral repositioning of the tube holder and an endotracheal tube held thereby along the track and to retain the tube holder at a selected position along the track without removing the device from the patient or an endotracheal tube from the device. A bite block is carried by the tube holder and slidable therewith along the track. The bite block has a tubular wall with a central opening along a length of the bite block and a pair of opposite open ends. The bite block is positioned spaced vertically from the track and has a portion extending rearward beyond the face contacting side of the track.
