Volvo engine line will be 2007-compliant

Volvo Trucks North America Inc will offer a complete line of Volvo diesel engines to meet the new emissions standards that take effect in 2007. The new family of engines will include 11- and 13-liter models, in addition to the 16-liter Volvo D16 introduced earlier this year. Volvo plans to launch the engines for customers and dealers during the first quarter of 2006.

Volvo has selected high-performance exhaust gas recirculation (HEGR) as the primary NOx emissions control and a diesel particulate filter (DPF) for particulate control for its EPA'07-compliant engines. Volvo engines for 2007 will simply use a higher rate of EGR to achieve the lower NOx emissions. All of Volvo's 2007 engines are designed to use the ultra-low sulfur diesel (ULSD) fuel mandated by the United States government to be available in the second half of 2006.

The 2007 engine family will include:

• 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 fully integrated into truck design

• Advanced centrifugal crankcase ventilation

The new family of engines will be built at the Volvo Powertrain North America plant in Hagerstown MD. Volvo will also continue to offer the 15-liter Cummins ISX as an option in its Volvo VN and Volvo VT highway tractors.
