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.

1. A vehicle having an internal combustion engine that is designed for combusting a fuel containing ethanol and an auxiliary heater, wherein an exhaust conduit of the auxiliary heater is disposed adjacent to an intake tube of the engine, in order to heat air located in the intake tube, and/orthe exhaust conduit of the auxiliary heater is disposed adjacent to a fuel supply line of the engine, in order to heat fuel located in the fuel supply line, and/ora connection element is disposed between the exhaust conduit of the auxiliary heater and the intake tube, in order to deliver all or some of the exhaust gas from the auxiliary heater to the intake tube,wherein the vehicle further includes a temperature sensor which is disposed in the intake tube and a regulating device which regulates an injected fuel quantity for the engine as a function of the temperature in the intake tube. 2. The vehicle as defined by claim 1, wherein a valve device is disposed in the connection element between the exhaust conduit and the intake tube. 3. The vehicle as defined by claim 2, wherein the valve device is a slide. 4. The vehicle as defined by claim 1, wherein the exhaust conduit of the auxiliary heater discharges into an exhaust system of the engine. 5. The vehicle as defined by claim 2, wherein the exhaust conduit of the auxiliary heater discharges into an exhaust system of the engine. 6. The vehicle as defined by claim 1, wherein the exhaust conduit of the auxiliary heater extends beneath the intake tube of the engine. 7. The vehicle as defined by claim 2, wherein the exhaust conduit of the auxiliary heater extends beneath the intake tube of the engine. 8. The vehicle as defined by claim 1, wherein the auxiliary heater is embodied as a water heater, which communicates directly with a cooling system of the engine, and the cooling system of the engine includes a blocking element, in order upon engine starting to disconnect the cooling system from the auxiliary heater. 9. The vehicle as defined by claim 2, wherein the auxiliary heater is embodied as a water heater, which communicates directly with a cooling system of the engine, and the cooling system of the engine includes a blocking element, in order upon engine starting to disconnect the cooling system from the auxiliary heater. 10. The vehicle as defined by claim 1, further including at least one access sensor, which indicates to the regulating device an intent by a driver to enter the vehicle, on the basis of which intent the regulating device actuates the auxiliary heater, in order to preheat the combustion air and/or the fuel for the engine. 11. The vehicle as defined by claim 4, further including at least one access sensor, which indicates to the regulating device an intent by a driver to enter the vehicle, on the basis of which intent the regulating device actuates the auxiliary heater, in order to preheat the combustion air and/or the fuel for the engine. 12. The vehicle as defined by claim 6, further including at least one access sensor, which indicates to the regulating device an intent by a driver to enter the vehicle, on the basis of which intent the regulating device actuates the auxiliary heater, in order to preheat the combustion air and/or the fuel for the engine. 13. The vehicle as defined by claim 8, further including at least one access sensor, which indicates to the regulating device an intent by a driver to enter the vehicle, on the basis of which intent the regulating device actuates the auxiliary heater, in order to preheat the combustion air and/or the fuel for the engine. 14. The vehicle as defined by claim 1, wherein the exhaust conduit of the auxiliary heater is subdivided into a first exhaust pipe and a second exhaust pipe.
