Volvo Trucks North America’s lineup of engines to meet 2007 emissions standards will include 11- and 13-liter models, in addition to a revised version of the 16-liter Volvo D16 introduced earlier this year.
Launched at the recent American Trucking Associations convention in Boston, they’ll be built at the Volvo Powertrain plant in Hagerstown, Md. You’ll first see them during the first quarter of 2006.
Details are still sketchy on the new Volvo engines, like all the others, and the
company would not discuss ratings.
As we’ve known for a while, Volvo’s new ’07 motors will use what the company
calls “high performance” exhaust gas recirculation as the primary NOx emissions
control, plus a diesel particulate filter. The new engines will use a higher rate of EGR to achieve the lower NOx levels.
Other features: high-pressure fuel injection with multiple injections per stroke;
increased peak cylinder pressures; single-stage variable-geometry turbocharger; reinforced base engine components to handle higher internal loads;
high-capacity cooling system; and “advanced” centrifugal crankcase ventilation.
Volvo says the new engines will “maintain the level of fuel economy demonstrated
by the current Volvo D12, while delivering driveability even better than the D12’s.”
The 15-liter Cummins ISX will continue as an option in its Volvo VN and Volvo VT
