Abstract
A system for supplying fuel to an internal combustion engine for optimum efficiency in engine operation and fuel economy and for minimum objectionable exhaust emissions. The system pertains particularly to an internal combustion engine in an automobile, truck, or the like. Fuel is heated prior to introduction thereof into the engine. Fuel is introduced to the engine in accordance with intake manifold pressures.
