Abstract: An electromagnetic vacuum regulator responds to an electrical signal to supply a regulated vacuum output to vacuum sensitive air-fuel ratio control means in an engine carburetor, the air-fuel ratio control means providing a leaner air-fuel ratio with increasing manifold vacuum. The vacuum regulator includes a regulated vacuum output connected to the air-fuel ratio control means, a constant pressure input connected to a source of constant low vacuum and a variable pressure input normally supplied with the engine manifold vacuum so that the regulated output vacuum is normally always greater than the constant vacuum supplied to the constant pressure input. The carburetor throttle mechanism, however, includes means to actuate a valve opening the variable pressure inlet to the atmosphere during wide open throttle so that the regulated vacuum outlet supplies atmospheric pressure for a richer than normal air-fuel ratio regardless of the electric signal.

Abstract: An internal combustion engine air-fuel ratio control method and apparatus wherein a most favorable parameter selected from the group consisting of air, fuel, and recirculated exhaust gas is adjusted in response to detected deviation of the air-fuel ratio away from the desired ratio. Supplemental control is provided by means of the remaining parameters in the event that the most favorable parameter runs out of authority.

Abstract: An electromagnetic fuel injector is provided with a tapered armature valve plate operatively positioned by means of a locator so that it is arranged so as to, in effect, pivot from a spring biased position at which it seats against a valve seat associated with a plurality of orifice discharge passages located concentrically about the axis of the injector to a second position adjacent to the working surface of the pole piece means of the associate solenoid. Preferably, the electromagnetic fuel injector is of the bottom feed type whereby it can be supplied with fuel in excess of the amount to be injected, with the flow path of fuel being arranged so that the excess fuel will purge vapors from the injector and cool the solenoid coil therein.

CPC classification number: F02M26/57
Abstract: In an internal combustion engine, recirculation of exhaust gases is controlled to maintain the control pressure in a zone of the recirculation passage proportional to a reference pressure and thus to provide exhaust gas recirculation as a proportion of induction air flow. A duty cycle modulated valve controls an exhaust back-pressure port and an atmospheric pressure port to create the reference pressure, whereby the proportion of exhaust gases recirculated is established by the duty cycle and is independent of the induction air flow.

Abstract: In a carburetor, a linear motor assembly urges the metering apparatus against a biasing spring with a force related to the linear motor current, and an adjusting screw grounds a portion of the active turns of the biasing spring to vary its spring rate and thereby establish the position of the metering apparatus and thus the carburetor fuel flow for a selected linear motor current.

Abstract: An engine charge forming device controls the fuel metering orifice area in proportion to the throttled air flow area of the induction passage and controls the pressure drop across the fuel metering orifice in proportion to a vacuum signal which is substantially independent of the compressibility effects of throttled air flow; fuel flow is thereby proportioned to air flow throughout the range of engine operating conditions. Adjustments are provided for varying the fuel metering orifice area to set minimum and maximum fuel flows, and controls are provided for modifying the vacuum signal to vary air-fuel ratio.
