Scania to launch Euro 6-compliant engines

Scania is launching its first Euro 6-compliant engines, announcing that performance and fuel consumption will remain comparable to current Euro 5 engines.

Starting 31 December 2012, all new truck models sold in the European Union must meet the new Euro 6 emission standards. A year later, the same will apply to existing models, and sales of Euro 5 engines will be phased out.

But even today – more than two years before the law requires it – Scania has two engine alternatives that fulfil the new standards and are ready for launch. These engines make it possible for keen operators to take the next step and invest in the greenest technology available in the market. They will be able to benefit from lower motorway charges and other incentives that may be introduced by authorities. Another bonus is that vehicles with the latest emission standard also command a higher value in the second-hand market.

”We want to be ready as early as possible to offer these new engines to our customers,” says Gunnar Nyfjäll, product manager for Scania long-haulage trucks. Six-cylinder 13-litre engines featuring 440 and 480 horsepower will be available in Euro 6 versions for the G- and R-series truck ranges. Thus Scania will cover a large proportion of customer applications in the long-haulage and construction fields.

Scania’s Euro 6 engines are based on the new modular engine platform that was introduced in 2007. The driving experience will be unchanged, featuring good torque at low revs. Building them with the Scania modular product system simplifies development work as well as servicing and parts management.
The biggest difference is the entirely new exhaust gas aftertreatment system that is built into the silencer. This includes a particulate filter and twin selective catalytic reduction (SCR) catalysts with an advanced AdBlue dosage system that reduces nitrogen oxide (NOx) content.

According to the Euro 6 directive, the permitted NOx level is only a fifth as much as with Euro 5, and the particulate level is less than half. In addition, particulate matter will be counted according to a new method, and the limitation on the particle count will mean that a vehicle needs to be equipped with a particulate filter. The new Scania engines fulfil these emission levels by a wide margin.

Jonas Hofstedt, Head of Powertrain Development, says Scania has spared no effort to avoid fuel penalties on the new engines. “Operators will find that fuel economy, driveability and engine response are fully on a par with our Euro 5 engines,” Hofstedt says. “One of the new features for Euro 6 is the entirely new exhaust gas aftertreatment system that is built into the silencer.

“All the development work has been performed in-house at Scania,” he adds. “We have combined all the new technologies that Scania has developed in recent years: exhaust gas recirculation, variable turbo geometry, common-rail high-pressure fuel injection, selective catalytic reduction and particulate filtering. Add to that our own engine and exhaust management technology, which has now been integrated into one system.”


Euro 6 is a drastic downward step in emission levels compared with previous emissions standards. The European Union directive sets new limits on emissions of nitrogen oxides and particulate matter from heavy trucks. The Euro 6 standard is also a first step towards harmonisation of the emission rules in Europe, North America and Japan. It applies to new models starting 31 December 2012 and to existing models starting 31 December 2013. After that, all new trucks sold in the EU must meet Euro 6 standards.
