ABSTRACT:
Start-up assistance is provided for small low-horsepower gasoline fueled internal combustion utility engines. A portable supply of starting fuel, such as naphtha, benzine, benzol, ether or alcohol, is directly injected through an temporarily openable aperture effective as an indraft port and entered into the carburetor bore, or an intercurrent carburetion duct utilized between the carburetor and the engine's intake port, to thereby enable immediate intake of the starting fuel through the engine valving and permit spark ignition and combustion upon initial engine cranking. Manual starting fuel injection also serves to overcome engine start-up difficulty generally caused by the inferior low-temperature volatility of contemporary gasoline products. As a result, this occurrence of nearly immediate engine firing remarkably enhances the liklihood for carburetion and induction of the usual running fuel supply and continued engine operation.
