摘要： In a treatment for regenerating the purification capability of an exhaust emission control system, a technique for improving exhaust emission more positively is provided by supplying a reducing agent to the exhaust emission control system and allowing part of exhaust to bypass the exhaust emission control system. When an addition synchronous bypass control is carried out in which an reducing agent is added when an NSR is subject to NOx reduction treatment and the volume of exhaust passing through a bypass pipe out of exhaust passing an exhaust pipe is increased to thereby decrease the volume of exhaust passing through the NSR, a judgment is made (S106) as to which is larger a reduction in volume of Nox exhausted (S105) due to an increase in conversion efficiency of the NSR as the result of the addition synchronous bypass control carried out or an increase in volume of Nox exhausted (S103) due to an increase in exhaust passing through the bypass pipe. When a reduction in volume of NOx exhausted due to an increase in conversion efficiency of the NSR is judged to be larger than an increase in volume of Nox exhausted due to an increase in exhaust passing through the bypass pipe, the addition synchronous bypass control is executed (107).
摘要翻译：在再生废气排放控制系统的净化能力的处理中，通过向废气排放控制系统供给还原剂并使废气的一部分旁路废气排放控制系统来提供更积极地提高废气排放的技术。另外，在NSR进行NOx还原处理的情况下进行添加还原剂的添加同步旁路控制，通过排气管的排气通过旁通管的排气量增加，从而减小排气管的体积通过NSR的排气，进行判断（S106），由于执行了相加同步旁路控制的结果，由于NSR的转换效率的增加而使排气的Nox的体积减小（S105）更大，由于排气通过旁通管的增加，排气量减少（S103）的增加。当由于NSR的转换效率的提高而排出的NOx的体积减少被判定为大于由于通过旁通管的排气的增加而排出的Nox的体积的增加时，执行相加同步旁路控制（107）。

摘要： The exhaust gas discharged from an engine such as an internal combustion engine or the like is treated to convert harmful or noxious pollutant components such as nitrogen oxides, carbon monoxide and unburned hydrocarbons to innocuous compounds, by contacting the exhaust gas with two stages in series of a catalyst composition containing 8% to 20% by weight of copper as equivalent copper oxide, 1% to 5% by weight of cobalt as equivalent cobalt oxide, and 0.5% to 3% by weight of manganese as equivalent manganese dioxide, deposited on particles of transitional alumina having a surface area in the range of 200 to 400 square meters per gram. The copper and cobalt are at least partially present in the form of reduced oxides, and the catalyst may also contain 1% to 5% nickel as equivalent nickel oxide. Air is injected into the partially reacted exhaust gas between stages, so that a reduction of nitrogen oxides takes place in the first catalytic stage or bed, and oxidation of carbon monoxide and hydrocarbons to innocuous compounds such as carbon dioxide and water vapor takes place in the second catalytic stage or bed.

摘要： Exhaust gas cleaning catalysts are produced by alloying copper and aluminum with at least one of the elements, nickel and chromium, and eluting by alkali or acid means aluminum from the cooled alloy surface. Small amounts of other metals from the fourth or fifth period V.about. VIII groups, may be added to the catalysts by alloying, or by impregnation, for enhanced catalytic properties. The catalysts exhibit improved reduction of NO and oxidation of CO in an exhaust gas stream, in the presence of Pb, SO.sub.2, moisture and hydrocarbons (H.C) and at relatively low temperatures.
