Abstract
A system and method is provided whereby exhaust gases from a cold started internal combustion engine are rapidly brought to catalytic combustion conditions. Specifically, a closed system of a low pressure metal hydride heat exchanger and a high pressure metal hydride heat exchanger is provided which, upon engine ignition, effectuates hydrogen flow from the high pressure alloy exchanger to the low pressure alloy exchanger with rapid heating of the low pressure alloy due to hydrogen occlusion, and with the further provision that the heated low pressure hydride alloy exchanger is in heat exchange relationship with the cold started engine exhaust gases or the vehicle catalytic converter and provides heat necessary for initiation of catalytic combustion of pollutants in the said exhaust gases.
