US Patent:

39863514, Oct 19, 1976

Filed:

Feb 4, 1975

Appl. No.:

5/547069

Inventors:

Robert L. Woods - Kensington MD
Silas Katz - Silver Spring MD

International Classification:

F01L 134
F01N 114

US Classification:

60274

Abstract:

A method and apparatus for controlling the air flow in an internal-combustion engine that comprises an unthrottled variable-timing third valve engine modification. An unthrottled full charge of air is drawn into the cylinders during the standard intake stroke of a four-stroke internal-combustion engine. During the initial portion of the succeeding compression stroke, a portion of that full charge is discharged through a third valve. Thus, the same mass of air that would result from throttled engine remains in the cylinders to be compressed. This air quantity is adjusted by means of adjusting the timing of the opening and closing of the third valve in accordance with the power requirements of the engine. A full charge of air is utilized for a full load, while a lesser charge is utilized for a partial load. Power losses which result from conventional intake air throttling are thereby eliminated.

Appl. No.:

5/593834

International Classification:

B60K 4116

US Classification:

74863

Abstract:

This invention describes a system of control for a power source-transmission-load system such as might be used on an off-the-road vehicle, for example. The power source is an internal combustion engine having a known optimum characteristic of desired manifold vacuum versus engine speed. The transmission is a hydrostatic or hydromechanical transmission having infinitely variable speed ratio and having a control means for varying said speed ratio. The control system includes a transducer means for measuring engine speed and converting this quantity into an analog fluid pressure proportional to the speed. This analog fluid pressure proportional to speed is modified in a function generator to produce an analog fluid pressure which is proportional to the desired manifold vacuum as a function of engine speed. Means are provided for measuring the actual manifold vacuum and for comparing the actual manifold vacuum with the desired manifold vacuum on a continuous basis. This comparison produces an error signal which is amplified and used to control a hydraulic system to operate the control means in order to vary the transmission ratio of the hydrostatic or hydromechanical transmission to obtain a speed ratio such that will provide optimum engine conditions.

International Classification:

F02M 5910
G01F 132

US Classification:

123119R

Abstract:

A fluidic implementation of a constant mass airfuel ratio fuel-injection system which may be utilized, for example, in an internal combustion engine. The system includes a fluidic mass air flow sensor that produces a pressure oscillation in direct proportion to the mass air flow to the engine. The frequency of this oscillation is utilized to control a fuel flow metering device which delivers a fixed amount of fuel per oscillation cycle. In one preferred embodiment, the metering device may comprise a fixed displacement piston pump. In an alternative embodiment, the metering device comprises a constant pulse-width fluidic amplifier.
