摘要： A fuel control system for internal combustion engines including a stratified charge igniter, a secondary carburetor regulating fuel flow to the igniter and common cooling means for the igniter and pre-heating means for the fuel. The pre-heating means includes both heating grids that are geometrically arranged to contact and vaporize fuel supplied to the igniter from the secondary carburetor and heated fuel distribution apparatus.

摘要： A variable Venturi condition responsive carburetor wherein a control ring, movable in response to engine operating conditions regulates the amount of air that is mixed with incoming fuel as it passes through metering tubes to provide for total air fuel mixing prior to its being introduced into the combustion chambers of an internal combustion engine. The control ring also regulates the amount of fuel supplied through the metering stem, provides a means for providing automatic compensation for fuel mix changes necessary due to changes in atmospheric pressure such as will occur during altitude changes and regulates flow through a demand fuel circuit. An arrangement of fixed and movable Venturi elements is used to vary the fuel flow through the carburetor in response to the throttle linkage manipulation.

摘要： A variable Venturi, condition responsive, carburetor wherein a throttle linkage operated movable Venturi element cooperates with a fixed annular Venturi element such that the amount of fuel flow through the carburetor is regulated by the position of the movable Venturi element and an annular Venturi passage. Fuel flow for the engine at idle by-passes the Venturi, flow for normal driving speeds is proportioned by the position of the movable Venturi element and fuel flow for high speed engine operation is provided through the movable Venturi element in accordance with the position of the movable element in the carburetor.
