  • Method for detection of hydrocarbonaceous fuel in a fuel injection engine
    Patent number: 4412444
    Abstract: A method and apparatus for detecting the presence and quantity of fuel in a fuel/air mixture to the cylinders of a fuel injection engine is disclosed. A portion of the fuel/air mixture injected to the engine is diverted through a solid state sensor which, when included in a detection circuit, provides a resistance which is proportional to the amount of fuel in the mixture. The sensor reacts to the presence of the fuel vapors by providing a change in the voltage across the sensor.
