Abstract
The present invention relates to a vehicle, having an internal combustion engine which is designed for combusting an ethanol-containing fuel, and an engine-independent air heating system. An exhaust passage of the engine-independent air heating system is disposed adjacent to a suction pipe of the internal combustion engine in order to heat the air in the suction pipe. Alternatively or additionally, the exhaust passage of the engine-independent air heating system is disposed adjacent to a fuel supply line of the internal combustion engine in order to heat the fuel in the fuel supply line. A connecting element or connecting openings are disposed between the exhaust passage of the engine-independent air heating system and the suction pipe in order to pass the exhaust gas of the engine-independent air heating system completely or partly into the suction pipe.
