Abstract:
A throttle body assembly wherein a pair of throttle blades are counter-rotatably mounted in the induction passage and define at their juxtaposition venturi sections whose size is variable in accordance with the degree of rotation of the throttle blades. The blades are peripherally sealed with respect to the walls of the induction passage by means of wiper type seals affixed to each blade as well as by caged roller type seals.
A throttle body assembly comprises a throttle body having an induction passage therein with a pair of rotatively coupled, parallel shafts extending across the induction passage. A pair of blades are affixed to each shaft with each blade comprising a main blade section for selectively restricting the induction passage in accordance with shaft rotation and an auxiliary blade section which presents a curved confronting surface to an adjacent wall portion of the induction passage so as to preclude intrusion of any appreciable amount of induction air between each blade and the corresponding wall portion over the operative rotational range of the shafts.
A compact pump and motor assembly adapted for use as a fuel controller for an internal combustion engine fuel metering system. The assembly contains an electric motor, an interface housing assembly at one end of the electric motor and a pump housing assembly disposed on the side of the interface housing assembly opposite that of the motor. The motor shaft extends through the interface housing into a pilot hole in the pump housing and drives a pumping means contained within a pumping chamber defined by the pump housing and the interface housing. An inlet port, an outlet port, and a return port are provided in the pump housing. An inlet passage extends from the inlet port through the gear pump housing and the interface housing into a vapor separation chamber contained within the casing of the motor, the motor being of the wet type. A passage in the interface housing extends from the vapor separation chamber to the inlet of the pumping chamber. An outlet passage in the pump housing extends from the outlet of the pumping chamber to the outlet port.
A fuel circuit for an internal combustion engine comprising an electric motor driven control pump which is speed controlled by means of electronic control circuitry to precisely meter fuel to the induction air passage of the engine for mixture with induction air to achieve a desired fuel-air ratio. System performance is improved by causing the electric motor to run at a higher speed at engine idle than required to satisfy engine idle speed fuel demand by providing a return circuit from the outlet of the control pump to the tank. The return circuit is closed until the pump develops a predetermined minimum outlet pressure after which it opens to divert a portion of the pump output back to the tank via the return circuit. The return circuit is open at engine idle; however, as the engine fuel demand increases, the return circuit progressively restricts the return flow. In one embodiment, the return circuit closes at a predetermined outlet pressure somewhat below maximum pressure.
A compact pump and motor assembly adapted for use as a fuel controller for an internal combustion engine fuel metering system. The assembly contains an electric motor, an interface housing assembly at one end of the electric motor and a pump housing assembly disposed on the side of the interface housing assembly opposite that of the motor. The motor shaft extends through the interface housing into a pilot hole in the pump housing and drives a pumping means contained within a pumping chamber defined by the pump housing and the interface housing. An inlet port, an outlet port, and a return port are provided in the pump housing. An inlet passage extends from the inlet port through the gear pump housing and the interface housing into a vapor separation chamber contained within the casing of the motor, the motor being of the wet type. A passage in the interface housing extends from the vapor separation chamber to the inlet of the pumping chamber. An outlet passage in the pump housing extends from the outlet of the pumping chamber to the outlet port.
An improved fuel spray bar for spraying fuel into the induction passage of an internal combustion engine comprises a pair of spray tubes projecting from a spray bar body into the induction passage with a fuel dispersion element downstream thereof. Each spray bar tube has a plurality of spray orifices spaced along the length thereof for spraying fuel in a direction generally downstream of the induction passage. The improvement of the invention is provided by arranging one of the spray bar tubes upstream of the other so as to spray fuel onto the upstream surface of said other spray bar tube.
A throttle body fuel injection system comprises a fuel injector which sprays fuel into an induction bore of circular cross section for mixture with induction air passing through the bore. Fuel is injected exclusively upstream of the throttle blade and apertures are provided which, when the engine is idling with the blade occupying an idle position cracked open from its closed blade position, establish communication between points upstream and downstream of the throttle blade with the apertures being of sufficient size to conduct both the induction air and the entrained fuel as a mixture, allowing sonic velocities for best fuel atomization at engine idle.
A low friction mounting arrangement for the rotor element of a paddlewheel flowmeter, which avoids the use of costly jeweled spindle, journal block or ball race bearings and features a fixed spindle composed of a piece of nickel alloy music wire providing line contact engagement with and along the full axial width of a closely fitting rotor hub fully rotatable thereon and a self-centering positioning arrangement therefor.
