Earlier this month, the
US Environmental Protection Agency and the U.S. Department of Transportation
announced new greenhouse gas emissions
and fuel efficiency standards
for medium- and heavy-duty vehicles. The announcement has brought forth praise
and support.
Among letters in The Detroit
News a few days ago was the following from David Johnson, president and chief
executive officer of Achates Power Inc., of San Diego, California which is
developing opposed-piston diesel engines. Johnson writes:
“Thanks to the National Highway
Traffic Safety Administration and U.S. Environmental Protection Agency for
finalizing new truck efficiency standards for medium- and heavy-duty vehicles.
The new standards will save nearly two billion barrels of oil, $170 billion in
fuel costs, and reduce carbon pollution by 1.1. billion metric tons over the
lifetime of vehicles sold under the program.
“As a global engine development
company focused on engineering fuel efficient, clean transportation, we are
helping to ensure that vehicles are significantly more efficient and emit less
harmful emissions. We strive to do so without affordability constraints for
customers or profit concerns for manufacturers. Achates Power’s radically
improved Opposed-Piston Engine (OP Engine) can go a long way towards achieving
the goals of the new program.
“Package delivery vans,
tractor-trailers, buses, and other large trucks account for seven percent of
all vehicles on the roads but consume a quarter of all transportation fuel. The
new rule, finalized last week, will make trucks cleaner, more efficient, while
accelerating innovation in this growing sector.”
COMMENT. The
question is, however: How long will industry have to wait before Achates’
engines appear on the road? And Achates is not the only company developing opposed-piston diesel engines.

Achates claims that they will " by 2018 will have a 50 percent more efficient three-liter three-cylinder engine that will be suitable for passenger cars and trucks."
