US Patent:

48951846, Jan 23, 1990

Filed:

Dec 21, 1987

Appl. No.:

7/135738

Inventors:

Harold G. Abbey - Wellington FL

International Classification:

F02M 3900

US Classification:

13762529

Abstract:

A fuel injection system for a spark-ignition internal combustion engine in which combustion air is fed through an air flow meter to produce an input force whose strength is proportional to the mass-volume of the air. This input force actuates the valve member of a valve mechanism to whose input is supplied fuel at constant pressure, the valve member being displaced to an extent determined by the strength of the input force. The valve mechanism includes a fuel output chamber in which the pressure of fuel therein is a function of valve member displacement, this pressure being applied as a countervailing force to the valve member to cause it to assume a null-balance position at which the resultant mean fuel pressure yielded by the output chamber is proportional to the mass-volume of the combustion air, thereby attaining optimum fuel-air ratio conditions throughout a broad operating range.

Abstract:

A fluid-mechanical variable Venturi metering system having a contoured moveable element in an intake casing to an internal combustion engine whose shape and Venturi air passage(s) results in automatic shifting of the moveable element by aerodynamic force as a function of the mass-volume of the air passing through which with levers produces amplified outputs of displacement, countervailing force and differential air velocity pressure (Venturi vacuum) proportional thereto and compensating for temperature, moisture content and pressure whereby an output or combination of outputs or transducing of outputs applied to fuel control devices and systems provides air-fuel mixtures in optimum ratio for the entire speed-load range of the modern engine for naturally aspirated and supercharged Fuel Injection and Carbureted Injection systems.
