Abstract
In an intake air heater of an engine, in which a fuel containing alcohol is employed, the amount of hot air increases, as the concentration of alcohol in the fuel increases. Although the latent heat of alcohol is about seven times as large as that of gasoline, the amount of intake air is controlled in relation to the concentration of alcohol in the fuel, so that the intake air is heated, as a function of a concentration of alcohol, using an alcohol sensor.
