    • A fuel vaporizer for internal combustion engines employs a chamber exposed to and directly below the underside of the engine carburetor and a heater wall at the bottom of the chamber to receive drops of fuel released from the engine carburetor into the intake manifold. It also includes an apertured wall having an upperside forming the bottom of the intake manifold riser and an underside forming the top of the chamber. The heater wall may be heated by exhaust gases or bypassed water from the cooling system of the engine. The chamber is shallow so that surface of the heater wall of volume of the chamber will be high enough for rapid evaporation of fuel. The drops of fuel released from the engine carburetor drop down directly onto the heater wall and fuel vapor flows out of the chamber into the intake manifold. The apertured wall is not formed with holes in the peripheral area thereof to prevent the drops of fuel from splashing and/or spilling out of the chamber into the intake manifold.
    • 用于内燃机的燃料蒸发器采用暴露于发动机化油器底部并直接位于发动机化油器底部的腔室,以及在腔室底部的加热器壁,以接收从发动机化油器释放到进气歧管中的一滴燃油。 它还包括具有形成进气歧管立管的底部的上侧的多孔壁和形成该室的顶部的下侧。 加热器壁可以由来自发动机的冷却系统的废气或旁路水加热。 室是浅的,使得室的体积的加热器壁的表面将足够高以快速蒸发燃料。 从发动机化油器释放的燃料滴直接滴落到加热器壁上,燃料蒸气从腔室流出进入进气歧管。 多孔壁在其周边区域中不形成孔,以防止燃料滴溅入和/或从室内溢出进入歧管。
