A pump impeller assembly comprises a pump journal, an impeller fixed to one end of the pump journal, and a pulley fixed to the other end of the pump journal. The pump impeller assembly further comprises a pump bearing including an outer race surrounding the pump journal with the pump journal being adapted to rotate with respect to the outer race. The pump impeller assembly includes a support plate fixed to the outer race and lying in a radial plane with respect to the pump journal. The support plate has a plurality of locking tabs adjoining its peripheral edge. The locking tabs are circumferentially spaced apart from one another with respect to the pump journal. The locking tabs are adapted to interlock with locking lugs formed on the inner surface of a pump housing wherein the locking lugs are adjacent to a pulley opening in the pump housing through which the pulley extends and are circumferentially spaced apart from one another with respect to the pulley opening. The locking tabs are adapted so that the interlocking enables secure attachment of the support plate to the pump housing.

A mounting bracket for use with a base member having a flat upper base surface and an elongate shoulder extending upward from the base surface. The shoulder has a V-shaped recess extending along its length. The base member also has a tapped bolt hole adjacent to the base surface. The mounting bracket comprises a bracket member having an upper surface adapted to support a component, a flat lower bracket surface and a footing adjoining the bracket surface, and a pilot hole. The footing is inserted into the V-shaped recess with the upper beveled surface mating with the upper side of the V-shaped recess and with the bracket surface mating with the base surface. A connecting bolt extends through the pilot hole into the bolt hole. Screwing of the connecting bolt into the bolt hole results in insertion of the footing further into the V-shaped recess with the mating between the upper beveled surface and the upper side of the V-shaped recess resulting in the bracket surface being urged against the base surface.

An engine block heater is for an engine block having passage walls which define a fluid passage. The engine block has a heater socket which extends from the outer surface of the engine block toward its interior. The heater socket is separated from the fluid passage by the passage walls. The engine block heater comprises a heater housing having an exterior heating surface. The exterior surface has substantially the same shape as the heater socket enabling insertion of the heater housing into the heater socket and substantial heat transfer contact between a substantial portion of the exterior heating surface and the heater socket. A connector mounting is attached to the heater housing. The connector mounting is adapted for connection to an electrical power source. The heater housing has a heating element therein which can be heated by electrical connection of the electrical power source to the connector mounting enabling the heater housing to transfer heat to the engine block. A quick-release fastener is attached to the heater housing for releasable connection of the heater housing to the outer surface of the engine block.

A throttle cable linkage for a throttle valve comprises a throttle cam having a shaft opening enabling placement of the throttle cam on a throttle shaft of the throttle valve. The throttle cam includes a cable socket having a socket axis, an open socket inlet and a socket base. The throttle cam has a pilot trough and a ramp trough. The ramp trough has an interior ramp slot which extends along the length of the ramp trough and into the socket base. A throttle cable assembly includes a throttle cable and a cable knob. The throttle cable is sufficiently stiff so that control of a portion of it away from the cable knob can enable piloting of the cable knob through the pilot and ramp troughs causing the cable knob to fall toward the socket axis with the throttle cable falling through the ramp slot into the cable socket so that the cable knob is adjacent to the socket inlet. The stiffness of the throttle cable further enables application of a reverse force to the throttle cable to pull the cable knob into the cable socket.

An integrated induction system for providing fluids to the cylinders in an engine comprises a casing adapted for mounting on the engine. The casing has an air inlet and a plurality of fluid outlets. A plurality of air tubes are disposed within the casing so that air entering the air inlet flows through the air tubes and respective fluid outlets to the cylinders. A fuel injection assembly is mounted within the casing to inject fuel into the air exiting the air tubes adjacent each of the fluid outlets causing a mixture of air and fuel to enter the respective cylinders. Provision is made for venting the casing when the pressure therein reaches or exceeds a predetermined limit.

A fuel injection assembly is mounted within the casing to inject fuel into the air exiting the air tubes adjacent each of the fluid outlets causing a mixture of air and fuel to enter the respective cylinders. Connected to the fuel injection assembly is a carrier upon which are mounted induction system components. The casing is mounted on distribution mountings which are connected to the engine. The distribution mountings have passages to allow communication between air and fuel contained within the casing and the cylinders, and to allow communication between a supplemental fluid source and the cylinders.

Integrated induction system

A rotary combustion engine having a planetary rotor and a side intake port is provided with an internal exhaust gas recirculation system that is operable to connect the trailing region of the working chambers and the space below the trailing apex seal to the annular space between the side seals and oil seals on one rotor side only when the chambers near the end of the exhaust phase whereby the differential between the pressure of the exhaust gases and the vacuum of the inlet mixture causes the exhaust gases rich in unburned hydrocarbon that are in the trailing regions of the chamber during the exhaust phase to flow through the annular space to the intake port and thereafter be recirculated through the compression and expansion phase.
