Motor vehicle comprises a combustion engine with internal combustion of fuel and/or cold-flame product for driving the motor vehicle and thereby producing exhaust gas and an auxiliary power unit comprising an external burner and an expansion machine. A fuel tank with fuel provides energy to the burner and the combustion engine. The motor vehicle has a cold-flame-reactor with means for feeding the fuel from the fuel tank to the cold-flame reactor, and at least a portion of the fuel is pre-combusted to a cold-flame product in the cold-flame reactor.

We claim: 1. Motor vehicle comprising (a) a combustion engine with internal combustion of fuel and/or cold-flame product for driving the motor vehicle and thereby producing exhaust gas and (b) an auxiliary power unit comprising an external burner and a piston expansion machine, and (c) a fuel tank

We claim: 1. Motor vehicle comprising (a) a combustion engine with internal combustion of fuel and/or cold-flame product for driving the motor vehicle and thereby producing exhaust gas and (b) an auxiliary power unit comprising an external burner and a piston expansion machine, and (c) a fuel tank with fuel for providing energy to the burner and the combustion engine. wherein (d) a cold-flame-reactor is provided with means for feeding said fuel from said fuel tank to said cold-flame reactor, and wherein at least a portion of said fuel is pre-combusted to a cold-flame product in said cold-flame reactor. 2. Motor vehicle as claimed in claim 1, wherein said combustion engine is directly fed with fuel from said fuel tank and with cold-flame product and said burner of said auxiliary power unit is only fed with cold-flame product. 3. Motor vehicle as claimed in claim 1, wherein said combustion engine is exclusively fed with fuel from said fuel tank and said burner of said auxiliary power unit is exclusively fed with cold-flame product. 4. Motor vehicle as claimed in claim 1, wherein said combustion engine and said burner of said auxiliary power unit are exclusively fed with cold-flame product. 5. Motor vehicle as claimed in claim 1, wherein said burner of said auxiliary power unit is fed with at least a portion of said exhaust gas from said combustion engine instead of air. 6. Motor vehicle as claimed in claim 1, wherein a catalyst is provided for the treatment of said exhaust gas of said combustion engine and/or said auxiliary power unit. 7. Motor vehicle as claimed in claim 1, wherein means are provided for feeding said combustion engine with cold-flame product additionally to a mixture of air and fuel from said fuel tank said mixture being generated before entering the combustion engine. 8. Motor vehicle as claimed in claim 7, wherein said combustion engine has two operating modes, one of said operating modes comprises the combustion of cold-flame product and the other mode comprises the combustion of fuel from said fuel tank and means are provided for switching between said operating modes. 9. Motor vehicle as claimed in claim 1, wherein said combustion engine is a Diesel-engine. 10. Motor vehicle as claimed in claim 1, wherein said burner of said auxiliary power unit is a porous burner or a surface radiant burner. 11. Motor vehicle as claimed in claim 2, wherein the portion of said cold-flame product is less than 30% of the entire fuel fed to said combustion engine. 12. Motor vehicle as claimed in claim 4, wherein the portion of said cold-flame product is less than 30% of the entire fuel fed to said combustion engine. 13. Motor vehicle as claimed in claim 1, wherein said combustion engine is a diesel engine, wherein said combustion engine is fed a mixture of fuel from said fuel tank and cold-flame product, and wherein the portion of said cold-flame product is less than 5% of the entire fuel fed to the diesel engine. 14. Motor vehicle as claimed in claim 1, wherein said auxiliary power unit comprises a steam cycle. 15. Motor vehicle as claimed in claim 14, wherein said steam cycle comprises a steam generator which is exposed to heat generated by said burner, and said steam generator is further exposed to said exhaust gas of said combustion engine. 16. Motor vehicle as claimed in claim 1 wherein said auxiliary power unit comprises a Stirling engine.
