Portable engine-pump assembly
This patent describes an internal combustion engine adapted to operate on a running fuel of low volatility such as a kerosene based fuel or a diesel fuel. It comprises: a fuel inlet means for delivering fuel to the engine combustion chamber, means for supplying the running fuel to the fuel inlet means, and means for supplying a starting fuel having a relatively high volatility to the fuel inlet means for using in starting the engine, the means for supplying the running fuel comprising a carburetor means including a carburetor bowl, and idle duel supply passage means having an idle orifice restriction therein, a high speed fuel supply passage means having a high speed orifice restriction therein, and a fuel enrichment supply passage means constructed and arranged to bypass the high speed orifice and the idle orifice to compensate for the increased viscosity of the running fuel at extremely low temperatures by providing a substantial supply of fuel at the low temperatures.
