Fuel supply system for internal combustion engines

Claim 2

A fuel supply system for internal combustion engines comprising an engine rpm function control circuit for controlling fuel flow in conformity with the rpm of the engine, a manifold boosted pressure function control circuit for controlling fuel flow in conformity with the boosted pressure in the manifold, a summing impact modulator for causing fuel controlled by said two circuits to be injected, and a transverse impact modulator for supplying air in amounts such that proper proportions of air and fuel can be obtained in conformity with the boosted pressure.

Claim 3

A fuel supply system as defined in claim 1 in which said engine rpm function control circuit comprises a governor responding to the rpm of the engine, a pneumatic pressure control valve, a trigger mechanism, one shot circuit, and trigger means.

Claim 4

A fuel supply system as defined in claim 1 in which said manifold boosted pressure function control circuit comprises a pneumatic pressure control valve and a fuel flow control valve connected in series with each other.

Claim 5

A fuel supply system as defined in claim 1 in which said summing impact modulator has two injection ports and a drain.

Claim 6

A fuel supply system for an internal combustion engine having a crankshaft and an intake manifold with a pressure detection aperture, comprising: an engine rpm function control circuit including a governor responsive to the engine crankshaft, an air pressure control valve responsive to the governor, and a one-shot circuit responsive to air pressure from the air pressure control valve; a manifold boosted pressure function control circuit including an air pressure control valve responsive to pressure from the detection aperture in the intake manifold, and a fuel flow control valve connected in series with said pressure control valve; a boosted pressure detection circuit including a proportioning element connected to a line bypassed from the boosted pressure detection circuit and a transverse impact modulator connected to the output side of said proportioning element; and a summing impact modulator injection element including a fuel injection port and a fuel-air injection port for connecting an output of the one-shot circuit and the boosted pressure detection circuit.

Claim 7

A fuel supply system for an internal combustion engine having a crankshaft and an intake manifold with a pressure detection aperture, comprising: an engine rpm function control circuit including a governor responsive to the engine crankshaft, an air pressure control valve responsive to the governor, and a one-shot circuit responsive to air pressure from the air pressure control valve; a manifold boosted pressure function control circuit including an air pressure control valve responsive to pressure from the detection aperture in the intake manifold, and a fuel flow control valve connected in series with said pressure control valve; a boosted pressure detection circuit including a proportioning element connected to a line bypassed from the boosted pressure detection circuit and a transverse impact modulator connected to the output side of said proportioning element; and a summing impact modulator injection element including a fuel injection port and a fuel-air injection port for connecting an output of the one-shot circuit and the boosted pressure detection circuit.
