DETROIT, April 6 /PRNewswire/ -- At a media event held earlier today,
Detroit Diesel Corporation (DDC) reaffirmed its commitment to supplying and
servicing its 2007 Series 60(R) heavy-duty diesel engine for the motorcoach
and firetruck vehicle markets. Detroit Diesel has been supplying and
servicing engines to these two important commercial markets for several
decades.
"We want to reassure motorcoach and firetruck manufacturers that we are
committed to the sale and service of our 2007 Series 60 engine for them," said
Carsten Reinhardt, President and Chief Executive Officer of Detroit Diesel
Corporation. "We remain dedicated to supporting these markets in 2007 and
beyond and have made some very distinct refinements to our '07 Series 60 to
accommodate the unique designs of these vehicles."
Here's a look at some of the enhancements that have been added to the 2007
Series 60:
Reduced Exhaust Emissions -
The 2007 Series 60 is equipped with an exhaust Aftertreatment System that
replaces the muffler assembly in the exhaust system. The Aftertreatment
System dramatically reduces the amount of particulate emissions released into
the air. This unit includes a Diesel Oxidation Catalyst (DOC) and a Diesel
Particulate Filter (DPF) located in the exhaust system. During normal
operation, exhaust heat and the catalyst work together to oxidize the soot.
Additionally, the engine's Exhaust Gas Recirculation (EGR) System has been
optimized to dramatically cut NOx formation by returning a measured amount of
exhaust flow to the cylinders and lower combustion temperatures. The newly
designed system features a high-capacity, tube-and-shell EGR cooler that is
more rugged than the previous model.
Lower Oil Consumption with a Monotherm Piston -
The redeveloped Series 60 also offers lower oil consumption -- nearly 40
percent lower -- because of the introduction of a new piston design, changes
in oil control ring geometry and a smoother bore finish on the cylinder liner.
Improved Turbocharger Performance -
The 2007 Series 60 is equipped with an electronic variable geometry
turbocharger that automatically -- and precisely -- adjusts its boost across
the operating range, and delivers quick lift on the low end, where turbo lag
would otherwise occur.
New Fuel Injection System -
The new fuel system, which adds to the performance and cleanliness of the
engine, includes dual solenoid Electronic Unit Injectors that provide exact
fuel metering and enable independent injection pressure control.
Additionally, the system features a redesigned harness for more robust
performance and greater accessibility, as well as new technology that enhances
performance and reduces emissions.
Next Generation Engine Management System -
Detroit Diesel set the benchmark as the first fully electronic heavy-duty
diesel engine. Now Detroit Diesel is raising the bar with its next generation
electronic control system, DDEC VI. For 2007, the system employs a more
powerful microprocessor, increased memory and enhanced diagnostics. DDEC VI
is a key part of the strategy to achieve greater operating efficiency, cleaner
exhaust emissions and leverages all of its best features from past generations
of the system.
"The 2007 Series 60 represents a tremendous amount of investment, design,
engineering and manufacturing to bring a solid and highly reliable and durable
product to market," said Tim Tindall, Director of the EPA '07 Program for
Detroit Diesel Corporation. "I've been with Detroit Diesel for over 30 years,
and this is by far the most extensive program in terms of testing and
preparedness that I've seen. We are excited about the redeveloped Series 60
and introducing it for the motorcoach and firetruck markets."
While trying to maintain as much commonality as possible with engines used
in the truck market and provide customers the benefit of leveraged costs over
larger volumes, Detroit Diesel also recognizes the importance to tailor
specific features for the Motorcoach and firetruck markets. Significant
engineering time and investment are being made for specific component designs,
engine calibration and development, and system validation. Below are a few
highlights of the components that require special consideration:
For Motorcoach applications:
EGR Mixer Assembly -- The EGR mixer assembly has been mounted transversely
to the coolant package so the connection to the radiator assembly is routed
up, over or across the front of the engine.
Oil Pan -- The motorcoach market requires a low profile rear sump oil pan
because the engine is in a "pusher" configuration, whereas a Class 8 engine is
in a "puller" configuration. Additionally, a distinctive design is required
for oil fill and oil dipsticks in order to accommodate the positioning of the
oil pan.
A/C Bracketry -- The Air Conditioning bracketry design is one-of-a-kind
for the motorcoach market because the volume of the space that needs to be
cooled is significantly larger than that of a Class 8 truck or a fire truck.
Cold Pipe -- The EGR Cold Pipe must accommodate distinctive routing
because the accessory options for the alternator and A/C systems are different
in a fire truck and a motorcoach.
For Firetruck applications:
Turbocharger Actuator -- Detroit Diesel has developed an innovative design
for the turbocharger actuator position -- it requires being closer to the
turbo -- due to the narrow tunnel through which the engine must fit on the
firetruck.
Cold Pipe -- The EGR Cold Pipe must accommodate distinctive routing
because the accessory options for the alternator and A/C systems are different
in a fire truck and a motorcoach.
Fire Commander II -- Based on success of the original Fire Commander, the
new hardware package was developed to work in tandem with DDC's DDEC VI
electronics system and will provide the same level of performance customers
have come to know.
For both the motorcoach and fire truck markets, the alternator bracketry
is a special design because the electrical demand of a motorcoach and a fire
truck are significantly higher than that of a Class 8 truck. As a result, the
alternators that charge those systems are larger and require larger brackets
in order to mount to the engine. And, the requirements of these markets
dictate finely tailored calibrations to meet the needs of their customers.
Detroit Diesel is a pioneer in the motorcoach and firetruck markets. Over
the course of the last several decades, Detroit Diesel has had a significant
presence in both the motorcoach and firetruck markets, many times serving as
the only heavy-duty diesel engine supplier to many OEMs.
Detroit Diesel Corporation is a leading manufacturer of on-highway heavy-
duty diesel engines for the commercial truck market. The company offers a
complete line of engines from 170 to 515 horsepower for the on-highway and
vocational markets. Through its corporate headquarters in Detroit, Michigan,
Detroit Diesel is engaged in the design, manufacture, sale and service of
these products, in addition to supporting alternative and hybrid engine
strategies for the commercial truck marketplace. Detroit Diesel is a
subsidiary of DaimlerChrysler and part of the Freightliner group of companies.
