Exhaust Emissions Control Developments A SELECTIVE REVIEW OF THE DETROIT
ثبت نشده
چکیده
The Society of Automotive Engineers’ (Sm) Detroit World Congress in the Cob0 Center (5th-8th March) was a great success, with some 50,000 delegates, and about 1300 technical presentations. There were many well-attended sessions on the control of engine exhaust emissions, and this selective review focuses on papers concerned with platinum group metal @gm) catalysts. Platinum oxidation catalysts are used in selective catalytic reduction systems which use ammonia or urea, but these are not discussed here. The reference numbers of papers mentioned are given, most being available in S A E ‘‘Smgle Publications” (1).

متن کاملModeling of Combustion and Carbon Oxides Formation in Direct Injection Diesel Engine
When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a combination of nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon dioxide, which contributes about 5% of the total volume, the diesel engine exhaust consists of elements which are part of...
