Volvo Trucks’ new engine improvements offer fuel savings

Volvo Trucks are upgrading its D11 and D13 diesel engines for its FH, FM and FMX models to meet the new Euro-6 Step D regulation which also contain a number of improvements that will enable transport operators to reduce their fuel costs.

“With fuel chalking up about one third of hauliers’ costs, we continue to turn every stone in order to find new ways of reducing fuel consumption in our trucks,” says Claes Nilsson, President of Volvo Trucks. “This time, a combination of small improvements enables significant cost savings for our customers without compromising performance or productivity.”

The new Euro-6 Step D regulation focuses on ensuring that vehicles conform to the emissions standards in normal operations of use. Volvo Trucks’ steps to fulfil the more stringent emissions standard include new engine software and improved coating in the exhaust after-treatment system.

The upgraded D13 diesel engine also uses a new VDS-5 low viscous oil type and new piston oil scraper rings that lower fuel consumption and internal friction. Additionally, the 500 hp engine saves extra fuel by having the same higher compression ratio as the 460 and 420 hp variants.

Volvo’s I-See map-based software, which previews the topography of the route and takes care of gear selection, acceleration and engine braking to utilise the truck’s moving energy in the best possible way, has also been improved with a number of upgrades. These include a new gear selection strategy and selective coasting, which enables a more efficient use of I-Roll, the freewheel function.

”These updates will support our customers in staying on top of the new emission regulation while improving fuel efficiency for our Volvo FH,  FM and FMX trucks”, says Claes Nilsson.

The new upgraded engines will be available to order from the end of December 2018
