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. As the alcohol fuel in the work chamber cools, the piston is forced by a spring inward into the alcohol filled chamber, causing aspiration of gasoline into the gasoline chamber which upon starting of the engine and a build up of pressure in the alcohol work chamber gasoline line is injectable by means of an alcohol fuel pump, via a gasoline delivery line and a gasoline fuel injection valve into the air intake tube until such time as the engine has attained a sufficiently high temperature then only alcohol is used in operating the engine.
