The present invention provides a self-replenishing liquid water source onboard an automobile for supplying liquid water to an electrolyzer, such as an on-board hydrogen generator useful for the suppression of unwanted emissions. While automobiles typically have water reservoirs resupplied by a person, the invention provides a passive means of water collection for reliable replenishment due to operations of the automobile itself. The invention provides condensate from the engine exhaust gas by cooling a region of the exhaust system using cooling fluid from the engine coolant system. The cooling fluid is circulated during a period following the engine cold start event when the heat load on the engine coolant system is low.
In an automobile having an exhaust system, a catalytic converter disposed in the exhaust system, and an onboard electrolyzer that uses liquid water to produce hydrogen gas for introduction to the catalytic converter to reduce cold start emissions, the improvement comprising:
