Abstract:
1. An operating system for an internal combustion engine, which provides reduced energy consumption and reduced air pollution, said operating system comprising: (a) a fuel system including heating means for heating at least a portion of fuel, while flowing to fuel injection means, to reach a temperature between 60° C. and about 95° C. prior to injection of said portion of fuel into a combustion system of the engine, wherein said temperature is below a vaporization temperature of the fuel at a delivery fuel pressure, but is above a vaporization temperature of the fuel at a pressure of said combustion system, said fuel system comprising: (b) an air intake system receiving air at ambient temperature and receiving the heated fuel, said air intake system vaporizing the heated fuel to cool the air and thereby increasing an air mass flow being delivered into said combustion system; and (c) control means for enforcing an essentially constant target air-to-fuel ratio in said engine, said target air fuel ratio being selected in the range of Lambda between 1.25 to 1.35, said control means including a controller, said controller being connected to an engine computer and engine sensors, calculating said target air-to-fuel ratio, and sending an appropriate signal to said engine computer to alter the portion of fuel injected by said fuel injector means accordingly.
