Volvo Trucks is upgrading its D11 and D13 diesel engines for its FH, FM and FMX models, ahead of the introduction of the Euro VI Step D regulation.

Claes Nilsson, president of Volvo Trucks, says the manufacturer has also used this opportunity to deliver new ways of reducing fuel consumption.

“A combination of small improvements enables significant cost savings for our customers without compromising performance or productivity,” Nilsson says.

Euro VI Step D focuses on ensuring that vehicles conform to the emissions standards in real-world operation – Volvo is achieving this with new engine software and improved coating in the exhaust after-treatment system.

The upgraded D13 diesel engine (pictured) also uses a new VDS-5 low viscous oil type and new piston oil scraper rings to reduce fuel consumption and internal friction. Additionally, the 494bhp engine saves extra fuel by having the same higher compression ratio as the 454 and 415bhp versions.

The upgraded engines are available to order from the end of this month.

Volvo is also improving its I-See system with 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 Nilsson.
