Managing heat with ‘cool’ tech

Keeping cool is not a problem for many of us this time of year, as temperatures plummet and snowflakes begin to fly. For commercial trucks and off-highway equipment, thermal management challenges exist no matter the season, particularly as increasingly stringent emissions requirements result in hotter-than-ever engines.

As Tenneco's CTO Dr. Ben Patel notes in this month's Q&A on page 35, “in the emissions game, heat is your friend.” Undeniably true-but that heat must be properly managed. Patel discusses active and passive strategies that his company is pursuing to harness heat for good, not evil (sorry, couldn't resist), and provides his opinion on the potential of waste heat recovery (hint: it will play a role, eventually).
