    • A desulfurization method of a nitrogen oxide absorption catalyst when diesel is used may include determining how many times a regeneration of a diesel particulate filter (DPF) is completed, ending a DPF regeneration, if the number of times of the DPF regeneration reaches a predetermined value and entering into a desulfurization mode to desulfurize the DPF, ending the desulfurization mode after the desulfurization mode is performed for a predetermined time, and calculating a particulate matters (PM) amount that is trapped in the DPF after the desulfurization, compensating the trapped PM amount, and determining a time of the DPF regeneration. A desulfurization timing is determined based on the number of times that the DPF is regenerated to be able to simplify the desulfurization logic and also reduce the memory of ECU, when the LNT catalyst is poisoned by a small amount of sulfur included in exhaust gas.
    • 当使用柴油时,氮氧化物吸收催化剂的脱硫方法可以包括如果DPF再生的次数达到预定值,则确定柴油机微粒过滤器(DPF)的再生次数完成多少次,结束DPF再生 进入脱硫模式,对DPF进行脱硫,在脱硫模式进行规定时间后结束脱硫模式,计算脱硫后的DPF中捕集的颗粒物质(PM)的量,补偿被捕获的PM量 ,并确定DPF再生的时间。 当LNT催化剂被废气中包含的少量硫中毒时,基于DPF再生次数能够简化脱硫逻辑并减少ECU的存储量来确定脱硫时间。
