Abstract
The present invention provides a multi-phase fuel system for an internal combustion engine. More specifically, when the multi-phase fuel system is applied to a vehicle, the higher volatility (lower boiling temperature) components of fuel are supplied to the engine in a vaporized gaseous form while the lower volatility (higher boiling temperature) components of fuel are supplied to the engine in an atomized liquid form. In this manner, the multi-phase fuel system is capable of providing a more optimum lean air/fuel mixture for better fuel economy and emissions control during normal operating conditions while being able to quickly enrich the fuel mixture in response to sudden increases in load demand.
