The next step towards cleaner and more fuel-efficient engines. Several small advances results in a big improvement. Giving increased engine torque and response at low rpm on the D13 engine. As well as longer oil drain intervals on the D11 engine. This means less environmental impact.
Excellent torque at low revs. An extremely wide max torque range. And peak torque meets peak power. Compare our torque curves and you’ll see the difference. Climb in the cab and you’ll feel it – incredible acceleration, unrivalled pulling power and a fuel-efficient, pleasurable ride at speed.
Common-rail injection for all engines and fine-tuned software to give the best engine control: plus, lowered internal friction. Everything in order to optimise fuel-efficiency, and give improved engine torque and response at low rpm. This makes a difference to your bottom line. And to the environment.
Our patented engine brake, VEB+, uses a unique camshaft design to absorb up to 375 kW (510 hp) on the D13 engine. On the D11, the Volvo Engine Break (VEB) absorbs up to 290 kW. Coupled with our I-Shift transmission system and clever cruise control, you can maintain a high average speed, without compromising safety or fuel economy.
We've taken another leap towards cleaner transportation and reduced environmental impact with our Euro 6 engines. You can feel the improvements in torque and fuel-efficiency. And we’ve halved particulate emissions and reduced oxides of nitrogen by nearly 80% versus Euro 5.
New engine components improve gas-flow and ensure the exhausts reach the after-treatment system at optimum temperature.
2. Seventh injector
(not necessary on D11K and D13K420 engines)
A special diesel injector is used for heat management of the DOC and ensures the efficiency of the Diesel Particle Filter and good SCR functionality.
3. Diesel Oxidation Catalyst (DOC)
The DOC produces the NO2 necessary for the Diesel Particle Filter to efficiently combust the particulates. In cold conditions, it also provides the heat needed for regeneration.
4. Diesel Particulate Filter (DPF)
The filter collects and stores particulate matter (PM) until it’s burned off during regeneration. Regeneration happens automatically – you don’t need to take any action.
5. Selective Catalytic Reduction (SCR)
In the mixing zone, the exhausts are sprayed with AdBlue. When they reach the catalyst, the nitrogen oxides (NO2) are efficiently transformed into harmless nitrogen gas and water.
6. Ammonia Slip Catalyst (ASC)
The last step before the tailpipe where the remaining ammonia (NH3), if any, is removed.
Choose from seven different power ratings. There are four 11-litre (D11) and three 13-litre (D13) options.
