Scania unveils new SCR-only Euro 6 450hp engine

Scania is widening the choice for environmentally concerned operators with a new addition to its already comprehensive range of Euro 6-certified truck engines.

Operators keen for a 450hp, 13-litre, 6-cylinder engine that produces 2,350Nm of torque from just 1,000rpm now have a choice of two solutions, depending upon their specific application requirements.

In its latest configuration, Scania is presenting an engine that employs only Selective Catalytic Reduction (SCR) after-treatment technology, and thus is expected to become a strong favourite among line-haul fleets with an eye on low fuel consumption and their environmental credentials.

“Our success with the (European market) 410hp version of the 13-litre engine with SCR-only has spurred us to go further down the road to reduce both complexity and diesel consumption,” says Joel Granath, Head of Product Management for Scania trucks. 

“Our (European) customers now have a range of 18 different models of Euro 6 engines to choose from. This gives them unique opportunities to tailor their powertrains for optimal performance, regardless of driving conditions or application.”

Scania engineers solved the puzzle of providing high outputs while meeting tough Euro 6-emission requirements using only SCR so now customers benefit from increased freedom of choice with simpler solutions. 

The new Scania engine model – DC13 147 – requires neither a variable geometry turbocharger nor an EGR cooler.

“Just as with the extremely frugal 410hp model that appeared last (European) autumn, this engine is ideal, especially for line-haul customers who prioritise low fuel consumption, but don’t want to give up torque or driver comfort,” Granath says. 

“According to our own calculations running a Scania Streamline, this results in a 1 percent fuel saving compared with the previous model using both EGR and SCR – everything else being equal.”

However, engines using SCR-only technology do require more AdBlue, up to an average of 6 percent of diesel fuel. Scania’s Euro 6 engines employing both EGR and SCR use roughly half the AdBlue. 

For those who want to optimise their diesel fuel capacity, Scania offers a wide assortment of AdBlue tanks, including special solutions that use vacant space inside the frame in an intelligent way.

“We are convinced that Scania’s 450hp engine with only SCR will become a popular highway workhorse,” says Granath. 

“Using the SCR-only solution has been shown to lead to lower consumption, and it also saves some weight.

“Euro 6 customers who have the advantage of being able to run on up to 100 percent biodiesel should also look at the specially adapted version of Scania’s 450hp engine range. That version uses both EGR and SCR for after-treatment, just as before,” he says.

Scania in Australia will be able to make the SCR-only 450hp Euro 6 engine available, ideally to customers who run long distances, while the 450hp engine with both EGR and SCR Euro 6 compliance is also available to suit specific applications.
