摘要

The exhaust gas after treatment system has a multi-stage catalytic converter with a converter inlet, a converter outlet and a substrate, which has two ends. The substrate has multiple flow passages between the two ends of the substrate. The two wash coat stages have wash coat, which are formulated to generate hydrogen and ammonia form the exhaust gas inflow from the motor (10). The exhaust stream consist hydrogen, carbon and carbon mono oxide.
