Volvo lifted the veil on its 2007 D11, D13 and D16 heavy-duty diesel engines Monday, Feb. 13 at the Technology and Maintenance Conference in Tampa, Fla. Like other manufacturers, Volvo will continue to rely on Exhaust Gas Recirculation and will employ a diesel particulate filter to meet new stringent emission standards.
“There is intense interest in these engines,” says Peter Karlsten, Volvo Truck North America’s president and chief executive officer. “The technology is ready. The engines are ready. And Volvo is ready.”
The diesel particulate filter features a catalyst and a particulate filter. It will offer the diesel particulate filter in two configurations, including a Compact DPF that will mount under the cab on the right side of the truck. Exhaust will move through DPF’s catalyst, which is made of ceramic and coated with precious metals, transforming into harmless gas. Other pollutants will be trapped in the particulate filter.
In normal over-the-road operations, the DPF will do its job in a passive regeneration mode, relying on hot exhaust gases to help the catalyzing process. In some applications, the engine will squirt a small amount of diesel into the DPF to improve the process. The emission systems will add between 120 to 150 pounds over a traditional muffler, which the DPF replaces. Ash will have to be cleaned from the filter at a scheduled PM, but Volvo says that PM event will take place well beyond the 150,000-mile government-required interval.
The new engines, which will feature an electrically actuated variable geometry turbocharger and other design element changes, will cost more than predecessors; Volvo will apply a $7,500 surcharge to the cost of a new Volvo whether a customer specs a Volvo D11, D13, D16 or Cummins ISX engine.
