Abstract
The invention relates to a fuel metering and distribution system for an internal combustion engine comprising an open fuel reservoir 18 into which fuel is metered and a set of capillary tubes 20 each extending from the fuel reservoir 18 to a point in an induction manifold adjacent the intake valve of a respective one of the engine cylinders. The fuel may either be metered by a carburettor-like arrangement drawing fuel from a float chamber or by means of a single solenoid valve connected between the reservoir and a source of fuel under pressure. The ends of the fine tubes terminate in the fuel reservoir immediately above the fuel level, whereby as the fuel rises, the additional fuel metered into the reservoir is sucked into the fine tubes and transferred directly to the engine cylinders.
Claims7
A fuel metering and distribution system for an internal combustion engine comprising an open fuel reservoir, a plurality of fine tubes each extending from the fuel reservoir to a point in an induction manifold adjacent the intake valve of a respective one of the engine cylinders, and means for introducing fuel into the reservoir at a controlled rate dependent upon the rate of air flow to engine cylinders, the ends of the fine tubes terminating in the fuel reservoir immediately above the fuel level, whereby as the fuel rises, the additional fuel metered into the reservoir is sucked into the fine tubes and transferred directly to the engine cylinders.
A system as claimed in any preceding claim, wherein the metering of fuel into the reservoir is achieved by sucking fuel into the reservoir from a float chamber by applying above the fuel level in the reservoir a low pressure derived from a venturi in the induction passage of the engine.
A fuel metering and distribution system substantially as herein described with reference to and as illustrated in FIGS. 1, 2 or 3 of the accompanying drawings.
