Unrivalled power and performance
THE D5K AND D8K ENGINES
Four or six cylinders. 5.1 or 7.7 litres. Plenty of torque, lots of power and a fast response time. Our D5K or D8K engines are designed for the city – giving you maximum productivity and profitability, every working day.
Meet your engine
With its broad output range and impressive response, the Volvo D8K engine is ideal for inner city distribution. Smaller and lighter, the D5K is designed for gross weights between 10 and 16 tonnes. And is one of the strongest, most powerful four-cylinder engines on the market.
A smooth ride, guaranteed
Quick acceleration. Easy low-speed handling. First-class power. The D5K and D8K engines produce a wider, flatter torque and a better response at low rpm. Maximum torque is 800 to 900 Nm for the D5K and 950 to 1,050 Nm for the D8K, significantly lessening the need for gear changing.
No matter which engine is in your Volvo FL, you’ll have the power you need: 210 or 240 hp for the D5K, 250 or 280 hp for the D8K. Combined with the Volvo FL’s excellent maneuverability and lightning-quick response, they’ll get you there quickly and efficiently.

Ready for biodiesel
All power levels for D5K and D8K engines are certified for synthetic diesel (HVO). There is a variant of our D5K 240 engine will run on pure biodiesel (B100) – certified for Euro 6. It’s the perfect option if you want to help the environment, and enjoy the incentives available in your market.
Same power, lower emissions
Our Euro 6 engines are a huge leap towards cleaner transportation and reduced environmental impact. Power and fuel-efficiency are on par with Euro 5 models, but we’ve halved particulate emissions and reduced oxides of nitrogen by nearly 80%.
Our Euro 6 solution
New engine components improve gas-flow and ensure the exhausts reach the after-treatment system at optimum temperature.
2. Seventh injector
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.
Our D5K and D8K engines are equipped with a Diesel Particle Filter (DPF). It captures and processes the microscopic soot particles in engine exhausts during regeneration, leaving only a fine ash. The process is automatic, but when manual regeneration is needed – within an environmental zone for instance – you’ll be alerted well in time.
