Fuel supply system

Abstract

Abstract In a fuel supply system for an externally ignited internal combustion engine with compression of the fuel/air mixture, in which air flow-measuring means and a randomly operable throttle valve are arranged successively in the air intake suction pipe of the engine, and the meauring means is moved, in proportion to the air amount flowing through the suction pipe, against an at least substantially constant resetting force and thereby displaces the movable member of a distributing valve arranged in the fuel line in order to meter a fuel amount proportional to the air amount, and wherein a pressure liquid of at least substantially constant pressure, which is continuously delivered through a pressure line, serves to transmit the resetting force and acts upon a control slide valve to effect the resetting, the pressure of the liquid being variable by means of at least one regulated pressure control valve which is controlled in dependence on characteristic engine data, there is described an improved control cell adapted for temperature-dependent operation and which comprises a cell housing, bimetallic spring means, and heat-conducting tongue means jointly mounted in the housing for the conduction of heat from the tongue means to the bimetallic spring means and insulated against heat losses to the housing, electrical heating means associated with the tongue means, and fuel pressure regulating means comprising a control spring mounted in the housing, the bimetallic spring means being adapted for engaging the control spring and reducing the force of the spring at temperatures below the operational temperature of the engine.
