Abstract
An engine assembly may include a crankcase ventilation assembly having a fuel separator assembly. The fuel separator assembly may include a condensing unit and a vaporizing unit. The condensing unit may include a gas region and a liquid retaining region. A gas inlet may be in fluid communication with the gas region and a gas flow from the engine block including fuel vapor. The condensing unit may convert the fuel vapor to liquid fuel. The first gas outlet may be in fluid communication with an engine air inlet and provide a remainder of the gas flow thereto. The fluid region may store and provide the liquid fuel to the vaporizing unit through a liquid inlet. The vaporizing unit may convert the liquid fuel to fuel vapor and a second gas outlet may provide the fuel vapor to the air inlet.
