In addition to a heavy-duty starter, start-stop systems require such components as enhanced engine control, battery management, DC/DC converters, and more robust crankshaft sensors.

I think Patton's comments at the end are the message to all engineers working on this next design challenge. While start-stop hybrids may impose real design challenges in terms of wear and tear on parts and some of the other issues Chuck highlighted, the real aim for these systems is that the consumer shouldn't know or shouldn't care that the car they're driving has any kind of stop/start technology. They will care about the value proposition of the technology--i.e., better fuel consumption, less cost, better environmentally--and that the vehicle performs as they expect. Case closed.
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.
