REDUCTION OF N2O IN THE EXHAUST GAS OF LEAN-BURN PETROL ENGINES

摘要

(NOx storage catalyst, LNT or NSC) depending on the exhaust gas temperature to reduce the greenhouse gas N ₂ O (nitrous oxide) produced as secondary emissions during the regeneration of the storage catalyst in the total exhaust gas, Lt; RTI ID = 0.0 replay strategies. / RTI If the exhaust gas temperature is below 275 ° C-290 ° C, regeneration occurs using a strategy with a short pulse of 2 seconds and a gain of λ 0.95.
