Zircotec manages heat transfer in hotter exhaust systems

Automotive engineers may have thought that after a century or more, the problems of handling heat in all parts of the powertrain had been solved. But another is emerging that particularly affects commercial vehicles (CVs) and off-highway equipment: keeping exhaust heat only where it is wanted.

The new challenge affects exhaust systems and involves a combination of the auto industry's decades-old conflicting demands: efficiency, legislation, packaging and cost.
