Detroit Diesel unveils all-new DD13

Detroit Diesel introduced its new DD13 engine on Thursday, Aug. 7. A smaller version of the DD15 engine, the DD13 displaces 12.8 liters and features a 6-cylinder in-line configuration. The company says the new engine allows customers to demand economy, serviceability and performance.

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 from 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 eventually will cover three displacement categories: 13, 15 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.

“We have taken all of the lessons learned from our 70 years of building engines and applied this extensive history to our new engine,” says David Siler, director of marketing for Redford, Mich.-based Detroit Diesel. “The DD13, which is truly a culmination of our experience and innovations, delivers what our customers want — economy, serviceability and performance.”

Economy
Featuring many of the same technologies found in the DD15, but weighing 400 pounds less, the DD13 provides best-in-class fuel economy — up to five percent better when compared to the MBE 4000 that it will be replacing, according to the company. Built to spend more time in top gear, the DD13 pulls strong down to 1,100 rpm, while its 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 — a fuel delivery system designed to work in unison with Detroit Diesel’s DDEC VI engine management system to deliver the exact amount of fuel needed at just 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 company says.

“The DD13 is the only engine in its class to offer ACRS,” says Admir Kreso, director of HDEP engineering for Detroit Diesel. “We are utilizing our proven technologies across the board to help our customers save money.”

Serviceability
Detroit Diesel says the DD13 can go further between routine service intervals than any similarly spec’d engine — up to 50,000 miles. The engine was designed with convenience in mind: The cartridge-style filters (oil, coolant and fuel) are positioned above the frame rail, which makes service quick, easy and clean; and the maintenance-free crankcase breather further contributes to lower cost of ownership.

“Many of the design features we included enable customers to easily perform routine maintenance on their own,” Siler says. “This reduces time spent in the shop, off the road — and increases profitability during this ever-so-competitive time in our industry.”

And with 65 percent of the engine’s components being the exact same as the DD15, the DD13 offers maximum parts availability while ensuring that trained and qualified technicians always are available, the company says.

Performance
Detroit Diesel says the DD13’s torque curve provides an extremely wide peak torque range — up to 500 RPM wide — allowing drivers to easily find the DD13’s “sweet spot” for optimum engine performance. In addition, an asymmetrical turbocharger is designed to facilitate less moving parts when compared to VGT or waste-gated turbocharger designs, creating a more reliable and durable engine.

“The DD13 is designed to provide a remarkable B50 life of one million miles,” Kreso says. “The engine’s overall robust construction ensures it will be around for a long time.”

Other key engine features contributing to the performance of the DD13 include the Jacobs engine brake, which is integrated into the engine and offers up to 546 braking horsepower; a robust rear gear train; and a ribbed cast-iron block that helps lower noise vibration harshness.

Detroit Diesel says the DD13’s advanced design also allows for the smooth and seamless integration of urea-based BlueTec selective catalytic reduction technology for reducing emissions to meet U.S. Environmental Protection Agency 2010 standards without compromising power, fuel economy or performance.

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.
