Abstract
An emergency fuel for an internal combustion engine comprises a hydrocarbon solvent having a flash point of at least 100.degree. F. (such as about 65-75% paraffins and about 25-35% naphthenes, or about 75-85% paraffins and about 15-25% of C7 or higher alcohols, or an aromatic solvent, or an naphthalene-depleted aromatic solvent) and a cold starting additive. The cold starting additive may be provided in an amount of less than 5,000 ppm, preferably between about 1 ppm and 150 ppm. The cold starting additive is preferably selected from peroxides, azo compounds, cyano compounds, cetane improvers, or combinations of these compounds. When the emergency fuel is added to a cold engine, including one substantially at room temperature, the engine may be easily started.
