| 42 | Method for improving the operation of a motor vehicle driven with an internal combustion engine and motor vehicle with an internal combustion engine | US23946 | 1986-09-22 | US5000151A | 1991-03-19 | Hermann Eisele; Gergard Stumpp; Wolf Wessel |
| A method is proposed for improving the operating behavior of motor vehicles driven by an internal combustion engine and especially to reduce jerking or bucking. The jerking, caused by rapid changes in engine torque, is damped by adapting the torque of the engine to the increase in output of the drive train of the vehicle. To this end, the deflection of the engine relative to the motor body is detected and used for vaying the fuel quantity metered to the engine. A differentiating member interposed between the engine and the body acts upon the fuel quantity adjusting device of the fuel metering device. | ||||||

| An internal combustion engine has an exhaust manifold, an inlet manifold, and a carburetor which has a fuel jet. An oxygen sensor is mounted within the exhaust manifold, and produces an output signal according to the oxygen present within the exhaust gases. A computing means computes a corrective signal according to the oxygen sensor output signal. This corrective signal is fed as an input signal both to a means for supplying secondary air into the exhaust manifold, and also to a means for supplying bleed air to the jet of the carburetor. In a particular embodiment, a secondary air signal cutoff device selectively intercepts supply of the corrective signal to the secondary air supply means, and an air bleed signal cutoff device selectively intercepts the supply of the corrective signal to the air bleed supply means. These cutoff devices may be controlled according to vehicle road speed, engine temperature, engine rotational speed, inlet manifold vacuum, and the temperature of a catalytic converter. The corrective signal may be a duty ratio coded pulse signal. | ||||||

| 54 | Apparatus for mixing a vaporized liquid fuel with air | US660310 | 1976-02-23 | US4094291A | 1978-06-13 | Douglas R. Hamburg |
| A mixing apparatus for mixing a vaporized liquid fuel with air to develop a combustible air/fuel mixture is described. A finned swirl inducing member having a centrally located aperture is positioned downstream from a metering venturi and upstream from a plain tube mixing section. The centrally positioned aperture is sized and spaced to allow passage of a stream of vaporized liquid fuel delivered to the low pressure zone formed by a metering venturi. The fin members of the swirler are operative to cause a swirl of the air stream passing through the metering venturi. The swirling air stream prevents any direct contact between the vapor stream and the relatively cool side walls of the mixing section while causing mixing action between the interiorly constrained vaporized liquid fuel stream and the inner portions of the air swirl. | ||||||

| A fuel delivery system for an internal combustion engine is disclosed. The system includes primary and auxiliary heating means for vaporizing a liquid fuel, vapor storage means, carburetor means including metering venturi means for mixing the vaporized liquid fuel with atmospheric air to provide a combustible air/fuel mixture and means for controlling the delivery of vaporized fuel to the carburetor means. The carburetor means may be connected to a conventional internal combustion engine intake manifold for eventual delivery of the combustible mixture to the combustion chambers of the engine. The vaporized liquid fuel delivery means of the system includes a variable orifice vapor delivery nozzle for modulating the vaporized fuel content of the air/fuel ratio of the combustion mixture.The auxiliary heating means are operative to provide an initial supply of vapor to a vapor reservoir upon start-up of the internal combustion engine. Normal vaporization is provided by the primary heating means which include a vapor producing heat exchanger situated within the exhaust gas stream of the internal combustion engine to utilize waste heat from the exhaust gases to produce normal running vapor. The vapor so formed is stored in the vapor reservoir and is delivered under vapor pressure pressurization to the vapor delivery nozzle. The vapor reservoir includes a condensed fuel collection and return passage to return condensed liquid fuel to a fluid reservoir. The heating means are serially communicated to a source of liquid fuel through a coarse metering valve. The quantity of vapor within the reservoir is controlled by electrically sensing the amount of vapor within the reservoir and by electrically controlling the coarse metering valve to maintain a desired level of vapor within the reservoir. Liquid fuel is drawn from a conventional fluid reservoir such as a vehicle fuel tank and is heated to cause vaporization.The carburetor means is provided with a swirl inducing section arranged to be noncontactive with the vapor stream for promoting turbulent mixing of the vapor stream with ingested air at a point downstream from the swirl inducing means. The swirl so induced inhibits direct contact of the vaporized liquid fuel with the intake manifold prior to mixing. An electrical control system responsive to a variable resistance exhaust gas partial pressure of oxygen sensor is arranged to control the vapor fuel delivery nozzle through servo mechanism control of the variable orifice of the vapor delivery nozzle. | ||||||

The reservoir includes a movable wall member cooperative with means defining a housing to establish a variable volume vapor storage space. The movable wall member is referenced to the pressure of the air immediately upstream from the intake to the air and fuel metering portion of the engine. The housing includes a generally downwardly depending condensate collecting and return section. Vapor delivery conduits are positioned within the housing and support a thermally floating finned member operative to disperse vapor delivered to the vapor reservoir. The movable wall member is provided with position sensing means operative to provide an input to an electrical circuit for controlling the rate of vapor delivery to maintain a predetermined quantity of vapor within the vapor space.The electronic circuitry is operative to control a liquid fuel delivery means to provide quantities of liquid fuel to a liquid fuel vaporizer for charging the vapor storage space of the vapor reservoir. The electrical circuit is operative to vary a threshold voltage in response to the sensed position of the movable wall member. The variable threshold voltage is compared to a saw tooth wave train to generate a variable duration voltage pulse in order to selectively control the coarse liquid fuel delivery means. | ||||||
