  • Patent number: 4911116
    Abstract: A cold-start apparatus for alcohol-fueled internal combustion engines in which a certain quantity of gasoline is injected directly into the combustion chambers upon starting. To assure reliable start-up of the engine with the aid of gasoline, and beyond a predetermined temperature, the engine is operated with only alcohol fuel. In order to make gasoline available for the cold start without entailing a major expense, a gasoline storage and supply device is provided. The supply device includes a piston which divides the housing into a work chamber which is filled with alcohol fuel from a work chamber which is filled with gasoline.
