    • A method and apparatus for operating an electric ignition, internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer (50) that transfers heat from the engine coolant system to the fuel mixture as it leaves a fuel introducing device such as a carburetor (38); a fuel mixture heater (52) for heating the mixture above the vaporization temperature of the liquid fuel; and, a mixture homogenizer (54) for thoroughly stirring the fuel mixture that is located in the fuel mixture flow path intermediate the vaporizer and heater. The homogenizer is operative to compress the fuel mixture under certain engine operating conditions and the heater forms the intake manifold for the engine and includes branch flow paths (152a) and associated conduits (164) that communicate directly with each combustion chamber (32) through a valve controlled port (34a). The fuel mixture flow path from the homogenizer is constructed to minimize energy losses to the ambient.
    • 一种用于操作电点火内燃机的方法和装置,其通过利用通常排放到周围环境的热量来实质地提高燃料效率,以便在进入燃烧室之前调节和准备燃料混合物。 该装置包括燃料蒸发器(50),当燃料混合物离开燃料引入装置(例如化油器)时,其将热量从发动机冷却剂系统传递到燃料混合物; 燃料混合物加热器(52),用于将混合物加热到液体燃料的汽化温度以上; 以及用于充分搅拌位于蒸发器和加热器之间的燃料混合物流动路径中的燃料混合物的混合均质器(54)。 均化器可操作以在某些发动机操作条件下压缩燃料混合物,并且加热器形成用于发动机的进气歧管,并且包括分支流动路径(152a)和相关联的导管(164),其与每个燃烧室(32)直接连通,通过 阀控制端口(34a)。 构建来自均化器的燃料混合物流动路径以最小化对环境的能量损失。
