Detroit Diesel Corporation (DDC) released additional information
about its 2002 Series 60 engine program. DDC Vice Chairman and
CEO Lud Koci made the following statement, "Because of
recent and, to some extent, conflicting comments which have
been made in the heavy-duty diesel engine industry regarding
the October 2002 emission changes, we at DDC wish to assure
our customers regarding DDC plans going forward.
the time we signed the consent decree in 1998, DDC was concerned
that the time allowed to meet the new standards was minimal
in comparison to normal development and testing. But consistent
with our initial commitment, we have met our objectives. Having
said that, we still believe the industry would be well-served
by a longer period of time for customers to test our new engines
and prove to themselves that the 2002 Series 60 continues the
engine's long tradition of excellent performance, fuel efficiency
and low cost of operation. Unfortunately, given the compressed
development schedule, it is apparent that our industry will
face another up and down cycle due to pre-buying and delayed
buying. DDC wants to reassure our customers of our long-term
commitment to them, and our near-term commitment to provide
engines in October 2002 that meet EPA requirements without penalties
or aftertreatment devices, while giving our customers the best
engines will use Exhaust Gas Recirculation (EGR), which is the
same technology chosen by almost all engine manufacturers worldwide
to meet 2002 emissions levels. EGR adds some cost due to the
additional hardware involved. However, we believe there are
similar and substantial costs also involved in the one other
alternate technology considered.
remains committed to support its customers who have made the
Series 60 the number one selling heavy-duty engine model for
an unprecedented 10 years in a row, and we are confident the
EGR technology we are using is the best approach."
in 2001, in-use durability testing began on DDC's next generation
of EGR engines designed to meet the emissions standards scheduled
to take effect October 1, 2002. Since that time, six test vehicles
have each run over 1,000 miles per day, at 80,000 pounds gcw.
An additional test vehicle has been dedicated to cross country
runs between company-owned assembly plants. This testing program
is building on Detroit Diesel's ongoing experience producing
EGR-equipped, heavy-duty engines.
began production of heavy-duty cooled EGR engines over two years
ago for the NAFTA transit industry. Development work on those
engines began in the late 1990s, and a number of pilot models
were put in service in 1999. In the last two years, DDC has
placed over 2,500 heavy-duty cooled EGR engines into service.
8 and 15, 2002, two additional prototype Series 60 units were
placed into revenue service at one of DDC's largest customers.
These are 12.7 liter engines, rated at 430 hp and 1550 lb/ft
torque. This is a truckload operation with each unit running
2000-2500 miles per week. Additional 2002 Series 60 pre-production
test engines are being released to other customers for evaluation
and are being installed by a number of OEMs on their standard
announced, DDC will initially make approximately 95% of its
current ratings available in October 2002. As is its customary
practice, DDC will submit applications for 2002 emissions certification
to the EPA approximately 30-60 days in advance of scheduled
of the development process for the 2002 engine, the Series 60
-- already the lightest of the "big bore" engines
-- will become lighter still.
we put the finishing touches on the 2002 Series 60 engine, we
had the opportunity to reduce overall weight," said John
Morelli, Vice President - 2002 Engine Program. "While the
EGR cooler adds a few pounds, an enhanced gear train configuration
allows for a reduced size gear case cover and next generation
air compressor is more efficient, requires less horsepower,
and also saves weight," Morelli continued. "We have
six months before production ramps up so there is still time
to enhance the design of some of these components. The goal
is to have the 2002 Series 60 engine, in final production trim,
weigh less than the current configuration."
added, "We established many goals for the 2002 Series 60
engine during the initial concept phases. The first priority
was to meet the new emissions standards, but, at the same time,
we did not want to sacrifice any of the other product features
that have made the Series 60 engine so popular. We wanted to
maintain its reputation for excellent fuel economy and recommended
oil change interval. We also wanted to reduce engine noise,
improve performance of the engine brake, reduce weight, and
maintain the overall drivability that drivers currently enjoy.
We are meeting those goals in the relatively limited time we
have. We know, however, that the 2002 Series 60 engine is going
to continue to build on its own tradition of excellence.
fleets have raised concerns about the limited time they have
had to test these engines themselves, and while different customers
have varied expectations for in-use testing of new engines,
we have advised the EPA that new technology engines should have
adequate time for in-use demonstrations to meet industry standards.
However, with the progress made to date we will be ready to
the first production versions of the 2002 Series 60 engine are
scheduled to be available in September 2002.
