Exhaust gas preheating system |
abstract |
A system and method is provided whereby exhaust gases from a cold started internal combustion engine (41) are rapidly brought to catalytic combustion conditions. Specifically, a closed system of a low pressure metal hydride heat exhanger (44) and a high pressure metal hydride heat exchanger (48) is provided which, upon engine ignition, effectuates hydrogen flow from the high pressure alloy exchanger (48) with rapid heating of the low pressure alloy in the low pressure metal hydride heat exchanger (44) due to hydrogen occlusion, and with the further provision that the heated low pressure hydride alloy exchanger (44) is in heat ex-change relationship with the cold started engine exhaust gases or the vehicle catalytic converter (23) and provides heat necessary for initiation of catalytic combustion of pollutants in the exhaust gases. |
