POWERTRAIN VOLVO ENGINES

Volvo engines offer an impressive mix of power, efﬁciency,

and value. All are 2014 GHG-certiﬁed and have been optimized

to help you save up to 3% on fuel compared to previous Volvo

engines. And with up to 600 hp and 2,050 lb-ft of torque,

Volvo engines are built to handle the biggest loads

and the toughest roads.

Bigger hills,

fewer fuel stops.

Lower fuel costs, no special driver training.

Volvo’s SCR “No Regen Engine” leads the industry in using

fully passive regeneration to deliver near-zero emissions

of NOx and particulates. And because this process happens

automatically in most highway applications, your drivers

don’t need any special training—saving your ﬂeet both

time and money.

Driving near-zero emissions.

Volvo’s Selective Catalytic Reduction (SCR) system is a superior

solution to the EPA’s 2010 emissions standards, not to mention

a fuel- and cost-saving innovation for your ﬂeet.

Here’s how it works: high-NOx/particulate exhaust ﬂows

from the engine to Volvo’s diesel particulate ﬁlter (DPF),

where much of the exhausts particulate is removed. Next, before

the exhaust reaches the catalytic converter, diesel exhaust ﬂuid

(DEF) is mixed in. The DEF and catalytic converter change the

harmful nitrogen oxides into harmless nitrogen and water vapor,

and the truck’s NOx emissions register at near-zero levels. DEF

allows the engine to use less exhaust gas recirculation (EGR),

and maintain higher oxygen levels for better combustion.

Powerful and precise engine braking.

The Intelligent Volvo Engine Brake (I-VEB) is an enhanced

engine braking system that gives drivers precise control

over engine braking, and saves the truck’s brakes for when

they’re needed most. The D11, D13, and D16 engines

use a Variable Geometry Turbocharger (VGT), which, thanks

to intelligent software, “supercharges” the I-VEB system.

The result is phenomenal retarding horsepower at low rpm,

where the engine spends most of its time and where braking

is needed most. An impressive 600 hp retardation is available

at 2200 rpm with the D16, 500 hp at 2200 rpm

with the D13, and 410 hp with the D11.
