Abstract
System to reduce the amount of NOx in exhaust gases of a vehicle. The system includes a storage spacecontaining an agent, a SCR catalytic converter, an injection moduleto inject the agent upstream of the converter, a heat exchangercontaining a porous matrix, a shutter or injectorto control the flow rate of the agent to the exchanger, a valvebetween the storage space and exchanger, to transfer thermal energy to gases during the starting period. The shutter or injector controls the flow of agent into the exchanger during the starting period to raise its temperature, and is closed when gases have reached a certain temperature. The valve regulates exchanger pressure during a period at operating temperature and conveys the agent to storage space when the exchanger pressure is higher than storage space pressure.
