ABSTRACT:
An apparatus for providing fuel of a predetermined temperature and at a predetermined fuel rate based on demand to a carburetor of an internal combustion engine comprising a temperature regulated air flow mixer valve, a cool air inlet to the valve, a warm air inlet to the valve, a thermal balancing chamber connected to the outlet of the valve including a fuel pressure control valve mounted thereon, an expansion chamber mounted on the thermal balancing chamber and a fuel metering valve mounted at the outlet of the thermal expansion chamber. The fuel metering valve is responsive to engine vacuum. The thermally-regulated air flow mixer valve is responsive to the mixture in the intake manifold, and mixes the cool air and warm air to produce a desired temperature in the thermal balancing chamber. The warm air inlet includes a heat exchanger mounted in the exhaust manifold of the engine for warming intake air.
