Features: 355 hp and 1250 lb-ft torque Governed RPM 2100.

The Volvo D11 engine is an in-line six-cylinder design with a displacement of 10.8 liters, and ratings of 355 to 405 hp, with 1250 to 1550lb-ft of torque. With a lowengine weight of 2286lbs, the D11 provides excellent service in LTL and regional distribution tractors as well as weight-sensitive applications such as bulk tankers, petroleum transport, and bridge formula trucks. The D11 will now be offered in the Volvo VHD chassis, along with the VNM, VNL, and VAH models. Complete engine assembly and manufacture of the D11 crankshafts and camshafts are completed at Volvo Powertrain’s Hagerstown, Maryland plant.

The D11 engine is fully compliant with EPA’14 Green House Gas (GHG) emission standards, while still delivering outstanding fuel economy, reliability, durability and serviceability. Volvo EPA’14 engines offer 100% “Passive Regeneration” of the diesel particulate filter (DPF). Volvo trucks equipped with Selective Catalytic Reduction (SCR) emissions control systems for EPA’14 will not undergo driving or parked active regeneration of the DPF during normal operating conditions. Volvo engines have reduced diesel engine pollutants by 99% from original measured levels and produce Near Zero Emissions.

New Design Features:

Volvo’s 2014 GHG engines provide up to 2% greater fuel efficiency gained through optimized fuel delivery along with low friction cylinder improvements and clutched air compressors.

Volvo EPA’14 engines maintain EPA‘10’s 100% “Passive Regeneration” of the DPF.

Passive Regeneration, also known as NO2-Based Regeneration, occurs at 500 degrees F., a lower temperature than Active Regeneration, which occurs at 1100 degrees F.

Active Regeneration, or O2-Based Regeneration, uses high temperature to simply oxidize the soot out of the filter. The high temperature comes from ‘dosing’, or adding fuel through the 7th injector, located on the outlet housing of the turbocharger. This increases fuel consumption. This fuel oxidizes in the catalyst of the DPF where it raises the heat to the 1100 degrees required to oxidize the soot.

The 2014 engines will maintain a 7th injector. It will be used on all models to aid in warm-up of the emission control

system on a cold start-up. It will also be there in the extra-normal situation should a regeneration assist ever be needed, for example due to ‘extremely severe’ weather conditions.

A key enabler of Passive Regeneration is the correct NOx to soot ratio. This is critical. Volvo gets the correct NOx to soot ratio by using the low soot of the Volvo engine together with a higher NOx engine-out level. The increased NOx comes from a lower rate of EGR.

It has been shown with our test trucks, including some that have operated through two winters in stop-and-go urban delivery in hilly terrain (an arduous duty cycle), that none have yet experienced a single active regeneration in normal on-highway operation.

Advantages of No Active Regeneration:

No dash lights come on No special driver training or familiarization Much lower system temperatures Reduced thermal cycling

No limitations on where the driver can go

No interruptions of PTO activity Higher productivity Reduced consumption of fuel Lower operating expenses

The net result is a truck meeting the EPA’14 regulation with better fuel efficiency and near-zero NOx.

Carryover Design Features:

The following features, introduced in 2007, will be carried over intact into 2014.

Ultra High Fuel Injection Pressure – the design target for maximum fuel injection system pressures hadbeen raised 20% from 29,000 psi to 35,000 psi, for improved combustion and lower emissions. Thesuccessful dual-solenoid fuel injector used first with the US’02 D12D has been enhanced withproprietary actuation strategy.

Precision-Flow Cooled EGR System uses three state-of-the-art components to provide exactly the rightamount of EGR with fast response.

Sliding nozzle variable geometry turbocharger with electronic actuation –– toresponsively provide the needed EGR pressure.

Poppet-style hydraulic EGR valve – to accurately provide the needed EGR flow. Delta-pressure flow sensor – to provide precise measurement of the EGR flow and

integrate the signals back to the turbo actuator and EGR valve through a closed-loopelectronic management system.

These three system components, first introduced together in 2005 on the Volvo D16, combine to provide exceptional fuel economy and improved engine response.

Rear-Mounted Camshaft Damper – the torsional vibration damper and associated helical gear drive ofthe previous Volvo D12 overhead camshaft had been moved to the rear. This focuses the higher torsionalactivity from the fuel injection system directly into the component with the most inertial mass, the flywheel,in order to reduce high frequency displacement and increase reliability of external engine components.

Other Carryover design features include:

Single-piece rigid deck cylinder head with thirty-eight cylinder head fasteners. Like the block, the headis cast with proprietary technology in Volvo’s own foundry in Skovde, Sweden.

Steel cylinder head gasket for withstanding high combustion pressures.

Steel “ladder” reinforcement to increase stiffness of main-bearing area for today’s combustionpressures.

Volvo Engine Brake (I-VEB) - Intelligent, integrated compression brake engine retarder, with highretardation over the speed range. The engine brake software features a control stalk on the steeringcolumn that integrates the I-VEB with the service brakes and the I-Shift transmission with the followingcontrol functions:

o O – Offo A – Automatic. ‘Brake Blending’ applies engine brake at 50% when brake pedal applied.o 1 – 40% engine brakingo 2 – 70% engine brakingo 3 – 100% engine brakingo B – I-Shift transmission in maximum engine braking mode (when so equipped)

Volvo Vectro EMS engine electronics with enhanced diagnostics.

Full flow oil filtration with deep-flow canisters ensuring full media usage.

Bypass oil filter uses 5-micron filter to remove fine particles.

Low-return-flow fuel system cools fuel in the engine, not the fuel tank, providing consistent fueltemperature to the injectors regardless of extreme summer heat or frigid winter cold.

Available engine mounted primary fuel filter with in-cab water-in-fuel warning indicator.

All Volvo 2014 engines fully comply with the latest EPA mandates. This means all regulated pollutants have been reduced by 99% from untreated levels. Yet Volvo meets these demands with outstanding reliability and fuel economy. This is because we use a Selective Catalytic Reduction (SCR) system designed for the highest efficiency. Which allowed us to pursue a passive regeneration concept that uses NOx in place of diesel fuel to regenerate the soot, further reducing your cost of operation.

high-efficiency aftertreatment system

Volvo’s 2014 engines include high-efficiency aftertreatment systems that save you fuel and reduce maintenance.

For example, our SCR catalyst has a full 40˝ between the point of introduction of the Diesel Exhaust Fluid and where it meets the catalyst. This allows for the DEF to fully and completely convert to ammonia.

More importantly, our SCR catalyst has three bricks where others have two. This added capacity allows a greater catalyst efficiency, which enables our No-Regen strategy. We can adjust the EGR flow rate down while still eliminating all of the NOx in the catalyst. This allows us to deliver better fuel economy.

D11 drivetrain recommendations

It is critical to specify the truck properly to achieve maximum fuel economy and performance.

Ask your salesman to help you choose a rear axle ratio appropriate for your expected cruising speed and gross combination weight.

Volvo 2014 engines have been designed to achieve maximum fuel economy by cruising at low engine rpm. In D11 regional haul specifications, the target is 1370 rpm at 65 mph.

For example, with 70K lbs GCW, 1550 lbs-ft torque, 295/75R22.5 drive tires and 1.0 top gear ratio, the 2.47:1 axle ratio would come closest to the 1370 rpm at 65 mph recommendation.

With 0.78 ratio transmission, you should use a 3.25:1 ratio for 1406 rpm at 65.

Never specify Volvo engines for a cruise speed above 1600 rpm.
