| abstract |
A dual liquid fuel system for an internal combustion gasoline engine. The system delivers a volatile fuel to the carburetor or other fuel metering system on start-up and until the engine attains an operating temperature that does not normally require choking when using a normal gasoline. The system then switches fuels and delivers normal gasoline. The system includes means to partially vaporize gasoline and condense the vapor to obtain the volatile fuel used in start and warm-up. |
