摘要： In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.

摘要： An intake passage construction for an internal combustion engine has a primary intake passage for supplying an air-fuel mixture when the engine operates under a full range of loads and a secondary intake passage for supplying an air-fuel mixture when the engine operates under relatively high loads. A secondary slow fuel passage has a pair of fuel supply ports opening into the secondary intake passage, and a fuel drain passageway extends from one of the fuel supply ports and has a fuel discharge port opening into the primary intake passage. Ambient air can be introduced into the fuel drain passageway in response to a vacuum developed in the primary intake passage so that fuel can be drained from the secondary slow fuel passage to prevent vapor lock therein. The fuel discharge port of the fuel drain passageway may open into an induction pipe.
摘要翻译：用于内燃机的进气通道结构具有一个主进气通道，用于当发动机在全负荷范围内运行时供应空气 - 燃料混合物，并且当发动机在相对较高的温度下运行时，用于供应空气 - 燃料混合物的二次进气通道负载次级慢燃料通道具有通向二次进气通道的一对燃料供给口，并且燃料排出通道从燃料供给口中的一个延伸并且具有通向主进气通道的燃料排出口。环境空气可以响应于在初级进气通道中形成的真空引入燃料排放通道，使得燃料可以从次级缓慢燃料通道排出以防止气体锁定在其中。燃料排放通道的燃料排放口可以进入感应管。

摘要： A carburetor is provided with a fuel passage which leads to a float chamber and has an air bleed opening therein, and has a nozzle leading from the fuel passage to the intake passage to discharge fuel with air bubbles into it. The nozzle is formed as a multiconduit structure along at least part of its length, in order to improve breaking up of air bubbles in the fuel, and the atomization thereof.

摘要： A carburetor in which a fuel evaporator using a "porous ceramic body" is disclosed. The "porous ceramic body" has a three-dimensional porous structure with open boxes. The three-dimensional porous structure comprises an electrically conductive ceramic with a positive temperature coefficient. The carburetor is provided with an electrical arrangement so as to permit current to flow through the "porous ceramic body" to cause it to produce heat.

摘要： A fuel inlet fitting for an internal combustion engine carburetor has a depending hollow post with exterior lugs for cooperating with interior lugs depending about an inlet opening in the roof of the float bowl of the carburetor to draw and seal the fitting against the roof. A float valve is translatable in an outlet port through the post and is retained therein by an annular lip. The fitting and float bowl roof have detent means to lock the fitting in a fixed position with respect to the float bowl.

摘要： A multi-fuel engine includes an engine operable on a liquid fuel and first and second gaseous fuels. The multi-fuel engine also includes a liquid cutoff solenoid selectively operable between open and closed positions to allow and inhibit a flow of the liquid fuel to the engine and at least one gaseous cutoff valve selectively operable between open and closed positions to allow and inhibit a flow of the first and second gaseous fuels to the engine. A jet block couples the first gaseous fuel source and the second gaseous fuel source to a carburetor connected to an intake of the engine, with the jet block being located downstream from the at least one gaseous cutoff valve. The jet block includes a first gaseous fuel jet to meter the first gaseous fuel to the carburetor and a second gaseous fuel jet to meter the second gaseous fuel to the carburetor.
