BOSTON. Volvo Trucks North America Inc. (VTNA) today unveiled a complete family of Volvo diesel engines to meet the EPA 2007 emission standards here at the American Trucking Assns. (ATA) Management Conference & Exhibition. The new family of engines will include 11- and 13-liter models, in addition to the 16-liter Volvo D16 introduced earlier this year.
The OEM emphasized that the new engines will use proven technologies to meet the 2007 requirements. The engines will use high-performance exhaust gas recirculation (HEGR) technology as the primary NOx emissions control and a diesel particulate filter (DPF) to comply with EPA’s 2007 emissions rule. VTNA pointed out that tens of thousands of Volvo trucks with EGR systems have proved themselves in everyday operation on North American highways.
“Volvo engines for 2007 will simply use a higher rate of EGR to achieve the lower NOx emissions,” VTNA stated. “All of Volvo's 2007 engines are designed to use the ultra-low sulfur diesel (ULSD) fuel mandated by the U.S. government to be available in the second half of 2006.”
The new engines also feature:
- advanced, high-pressure fuel injection with multiple injections per stroke
- increased peak cylinder pressures
- single-stage variable geometry turbocharger (VGT)
- reinforced base engine components to handle internal loads
- high-capacity cooling system integrated into truck design
- advanced centrifugal crankcase ventilation
"Our testing indicates that the new family of engines will maintain the level of fuel economy demonstrated by the current Volvo D12, while delivering driveability even better than the D12's already excellent performance," said Peter Karlsten, CEO of VTNA. "We are taking full advantage of our EPA '02 experience to optimize the 2007 engine family for our customers."
The engines will be built at the Volvo Powertrain North America plant in Hagerstown, MD. VTNA will also continue to offer the 15-liter Cummins ISX as an option in its Volvo VN and Volvo VT highway tractors.
