the first to unveil Euro-6 engines two years ago, Scania now says it can do better with what it describes as secondgeneration versions of its 12.7-litre DC13 Euro-6 engines. It is also incorporating some fuel-saving technology as standard.
Scania is bundling together a series of improvements for its Euro-6 Gand R-series trucks under the title of Streamline, claiming that they offer up to an 8% improvement in fuel consumption compared with its first Euro-6 efforts, and up to 5% more than current models. Revisions to the engine have yielded another 10hp and 50Nm of torque, and 2%-3% better fuel consumption.
A similar improvement is expected to come from making Opticruise automated gear-shifting with a new eco mode, an integral part of the Streamline package. An added 2%-3% saving is forecast from the Scania Active Prediction, the terrain-sensitive cruise control system that also comes as standard in the Streamline's Opticruise system. Attention to detail around the cab's comer deflectors is claimed to tidy up airflow, as is a new sun-visor.
After launching only two ratings of its 12.7-litre DC13 Euro-6 engines in 2011, followed by four ratings of its five-cylinder 9.3litre DC09 engine last September, Scania has now rounded out its Euro-6 engine range.
They include three ratings of its 16.4-litre V8: 520hp, 580hp and, coming later, 730hp. And like Iveco, Scania also now sees merit in SCR-only engines that need no EGR to achieve Euro-6's NOx limit.
So the 320hp and 360hp versions of the SCR-only 9.3-litre engine unveiled last September are to be joined by a 410hp rating of an SCR-only 12.7-litre engine.
The first generation 12.7-litre Euro-6 EGR + SCR engines had nominal ratings of 440hp and 480hp; the second generation are uprated to 450hp and 490hp, with 2,350Nm and 2,550Nm of torque respectively.
