Abstract:
Provided is an engine for a working machine, wherein it is possible to use fuels having different concentrations of ethanol. A vaporizer (100) is used to adjust the mixing ratio of air and fuel within an air mixture, which is supplied to a combustion chamber (8), depending on the proportion of ethanol contained in the fuel being used.
