REDFORD, MI – Detroit Diesel has unveiled its new DD13 engine. A smaller version of the
DD15 engine, the DD13 displaces 12.8 liters, and features a six-cylinder,
in-line configuration. Designed for the less-than-truckload, regional
distribution, and vocational markets, the DD13 will be offered in output and
torque variants from 350 to 450 hp and 1,350 to 1,650 lb.-ft.
The DD13 is the second in a series of all-new heavy-duty
engines from Detroit Diesel that will eventually cover three displacement
categories: 13 liters, 15 liters, and 16 liters. Part of the Detroit Diesel
engine family, the DD13 shares a common base engine design that will be
leveraged on a global scale by Daimler Trucks.
Featuring many of the same technologies found in the DD15,
but weighing 400 lbs less, the DD13 provides best-in-class fuel economy — up to
five percent better when compared to the MBE 4000 (which it will be replacing).
Built to spend more time in top gear, the DD13 pulls strong
down to 1,100 RPM, which results in increased fuel economy. The DD13’s enhanced
cooling system reduces fan on-time — further contributing to the engine’s fuel
efficient design.
Another key feature is the engine’s
electronically-controlled Amplified Common Rail Fuel System (ACRS) — a fuel
delivery system that works in unison with Detroit Diesel’s DDEC VI engine
management system to deliver the exact amount of fuel needed at the right
moment, creating an optimal combustion event. Not only does this result in a
more fuel-efficient engine, it cuts NOx emissions without draining power.
The DD13 was designed with convenience in mind as the
cartridge-style filters (oil, coolant, and fuel) are positioned above the frame
rail. And the maintenance-free crankcase breather further contributes to the
low cost of ownership.
Other key engine features contributing to the all-around
performance of the DD13 include the Jacobs engine brake, which is integrated
into the engine and offers up to 546 braking horsepower; a rear gear train; and
a ribbed cast iron block that lowers noise vibration harshness. The DD13’s advanced
design also allows for seamless integration of BlueTec SCR technology.
The market launch of the DD13 will start with Sterling
Trucks and Freightliner in 2009, followed by Western Star in 2010. It will be
manufactured at the Detroit Diesel plant in Redford, Mich.
