The diesel engine's torque curve

Look at our curves

Excellent torque at low revs. An extremely wide max torque range. And peak torque that overlaps peak power in the mid rev range. 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.

Fuel efficiency puts money in your pocket as well as contributing to sustainability

Built-in fuel efficiency – and environmental care

Increased compression ratio on the 420 and 460 engines. New optimised turbo on the 500 and 540 engines. 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.

Volvo FH engine break

Volvo Engine Brake – VEB+

Our patented engine brake, VEB+, uses a unique camshaft design to absorb up to 375 kW (510 hp) on the D13. Coupled with our I-Shift transmission system and clever cruise control, you can maintain a higher average speed without compromising safety or fuel economy.

Cleaner, greener engines

With our Euro 6 step C engines, we take another leap towards cleaner transportation and reduced environmental impact. The perofrmance is the same, only the fuel consumption is lower. 

Our Euro 6 solution: an overview

How our Euro 6 solution works

1. Engine 
New engine components improve gas-flow and ensure the exhausts reach the after-treatment system at optimum temperature.

2. Seventh injector
(not necessary on the D13K420 engine)
A special diesel injector is used for heat management of the DOC and ensures the efficiency of the DPF and good SCR functionality.

3. Diesel Oxidation Catalyst (DOC)
The DOC produces the NO2 necessary for the DPF 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.
