ABSTRACT:
A heated fuel intake system for an internal combustion engine for introducing warmed air to the engine and air to a fuel supply circuit in a carburetor comprises a heat stove from which the warmed air is introduced into an air cleaner to heat the air to a temperature equal to or higher than a first predetermined temperature. The introduction of the warmed air from the heat stove is interrupted by a first valve unit when the temperature of the air to be fed to the engine has exceeded the temperature equal to or higher than the first predetermined temperature. The introduction of the warmed air into the air cleaner is again initiated when the temperature of the air inside the air cleaner becomes a value equal to a second predetermined temperature higher than the first predetermined temperature and, simultaneously therewith, an air-fuel ratio leaner is operated to introduce an additional air to compensate for the increased richness of the combustible mixture.
