日本大发汽车公司在确保车用发动机后处理装置尾气催化转化器的高效净化性能的同时,采用纳米技术,使贵金属催化剂的使用量与原来相比减少了70％。这种车用汽油机用新型催化剂由于采用纳米材料具有“自再生”的功能,所以又称为智能催化剂,并且应用在超低排放车(ULEV)及2002年日本市场销售的微型轿车上。 目前,为了实现“超低排放车”的普及应用目标,降低三效催化转化器的 Daihatsu Motor Co., Ltd., which uses nanotechnology to reduce the precious metal catalyst use by 70% compared to the previous generation while ensuring efficient purification of the exhaust gas catalytic converter of a vehicle engine aftertreatment device. The new catalyst for automotive gasoline engines is also known as an intelligent catalyst due to the “self-regenerating” function of nanomaterials. It is also used in ULEVs and mini-cars marketed in Japan in 2002. At present, in order to achieve the “ultra-low emission vehicles,” the universal application of goals, reduce the three-way catalytic converter
