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 hotterthan-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).
