Abstract: A diesel engine exhaust treatment system and method is provided which includes a platinum group metal trapping device (16) comprising cerium oxide or a perovskite material positioned between a diesel oxidation catalyst and an SCR catalyst. The platinum group metal trapping device traps trace amounts of platinum group metals which may be released from the diesel oxidation catalyst during engine operation and prevents them from accumulating on the SCR catalyst, preventing potential contamination of the SCR catalyst as well as ensuring that the performance of the SCR catalyst is uninhibited.

Abstract: The present invention provides an exhaust emission purifying apparatus. In the exhaust emission purifying apparatus, while an ammonia adsorbent is coated on a predetermined length portion on the exhaust inflow side of a carrier of a catalytic converter which reduces and purifies NOx in exhaust gas, a NOx reduction catalyst is coated on the remaining portion on the exhaust outflow side of the carrier of the catalytic converter. On the other hand, a first layer containing the ammonia adsorbent and the NOx reduction catalyst in a mixed state and a second layer containing a hydrolysis catalyst are coated in that order on a carrier surface of the catalytic converter. In a transition of an engine operation state, NOx is reduced and purified with the use of ammonia adsorbed to the ammonia adsorbent.

Abstract: In a method for the control of the supplied air/fuel ratio of an internal combustion engine (1) with a catalytic converter (5) which is located in the exhaust gas line (2) with an integrated oxygen reservoir (6), it is suggested that the air/fuel ratio be controlled as a function of at least one parameter of the internal combustion engine (1), at least one parameter of the catalytic converter (5), and/or as a function of the type and amount of the exhaust gas emissions currently occurring, in order to optimize the speed for adjustment of the admission or discharge of oxygen in the oxygen reservoir (6) contained in the catalytic converter (5) for favorable conversion of the exhaust gas emissions during transient operation of the internal combustion engine (1) and after deviations from the air/fuel ratio λ=1. As claimed in the invention, a “disturbance” of the exhaust gas composition which occurs during transient operation of the internal combustion engine (1) is corrected with a speed which takes into account both the current conversion demand by the catalytic converter (5) and also the current conversion performance of the catalytic converter (5) and thus makes possible improved overall exhaust gas conversion.
