Carburetor metering and hot air dilution system

Abstract

A carburetor metering system is provided comprising a fuel valve including a valve member movable with respect to a valve seat to vary the fuel flow, the valve member and the valve seat having substantially parallel inclined surfaces and which define therebetween a passage for the flow of fuel having a width corresponding to the distance apart of the surfaces and a length. A wick for use a carburetor metering system is also provided for absorbing liquid for vaporization into an air flow, comprising a cloth of woven strands and means for suspending said cloth in the air flow. There is also provided a spark plug for use in a fuel combustion system. A carburetor metering system is also provided, comprising air flow control valve for metering the flow of air in dependence upon the air pressure differential across the air flow control valve and to maintain the pressure differential at a predetermined value, a fuel valve being operatively connected to said air flow control valve means so that the fuel valve provides a respective increase and decrease in fuel flow rate in respective dependence upon air flow rate and a fuel pressure differential valve for maintaining the pressure differential across the fuel valve. A system is also provided for introducing hot dilution downstream of the carburetor metering system as a function of accelerator pedal position.
