Volvo engine line will be 2007-compliant
Jan 1, 2006 12:00 PM
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.
