The Environmental Protection Agency recently gave its nod of approval to Caterpillar's full line of off-road engines compliant with Tier 3 standards. Tier 3 regulations, which apply to clean diesel engines used in construction and mining machines and industrial power equipment, do not go into effect until January 2005. Caterpillar now has seven engine models certified under Tier 3 regulations, and these engines will be market-ready by this October. Caterpillar was able to meet these standards earlier by using ACERT technology. For more information on Caterpillar's clean engines, visit www.cat.com.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
