The invention claimed is: 1. An engine control system in a vehicle comprising: a diesel engine in the vehicle; a diesel fuel tank for supplying fuel to the diesel engine; a gasoline tank in the vehicle; a reformer for providing partial oxidation products from gasoline contained in said gasoline tank; a NOx trap coupled to the exhaust of said diesel engine. 2. The engine control system of claim 1 wherein said NOx trap includes a three-way catalyst. 3. The engine control system of claim 1 wherein said NOx trap is regenerated by said partial oxidation products. 4. The engine control system of claim 1 wherein said partial oxidation products include carbon monoxide, hydrogen, or nitrogen. 5. A method of controlling a diesel engine comprising: providing a diesel fuel tank; providing a gasoline fuel tank; providing a gasoline reformer; providing a NOx trap; generating partial oxidation products using said gasoline reformer; and regenerating said NOx trap with said partial oxidation products. 6. A method of controlling a diesel engine comprising: supplying gasoline to a partial oxidation reformer to generate reformate; and introducing the reformate into the diesel engine. 7. The method of claim 6 where in the reformate comprises hydrogen. 8. The method of claim 6 wherein the reformate comprises carbon monoxide. 9. The method of claim 6 wherein the reformate comprises hydrocarbons.
