Scania’s new kids on the (engine) block

With new Euro-6 certified biodiesel and gas engines already launched, Scania stays miles ahead of the competition, offering customers a range of engine possibilities for almost any application.

Scania has launched the very first Euro 6-certified truck engine that can run on 100 percent biodiesel fuel (EN 14214), offered with either 320 or 360 horsepower. Scania’s modular-built five-cylinder, 9-litre engine has an available torque of 1,600 Nm from 1,050 r/min as a 320, and 1,700 Nm from 1,100 r/min as a 360. These multifaceted engines are useful for both trucks and buses and, more importantly, their output is reduced by no more than 8 percent (due to the lower energy content) when run on only biodiesel.

Increased interest in biodiesel

“We’re seeing increased interest in biodiesel in a number of larger markets,” says Joel Granath, Vice President of Scania’s Product Management for Trucks. “As far as I know, no other manufacturer has presented Euro 6 engines for biodiesel. So we have great expectations about how these very flexible and environmentally-suited engines will be received.”

The versatile new engines are offered in both conventional diesel and in the aforementioned biodiesel version, with the latter running on any mix of both fuel types. The biodiesel engine must, however,  always be serviced as if it runs on biodiesel exclusively.

Less environmental impact

Nevertheless, biodiesel emits noticeably less carbon dioxide compared with conventional diesel. Exactly how much less depends on how the fuel has been produced. And thanks to the lower emission rate, using biodiesel often means qualifying for subsidies and tax breaks.

The launch of the current 320 hp and 360 hp engines for biodiesel is a first step in a launch of a range of Euro 6 engines from Scania that have a capacity to run on 100% biodiesel. In their basic configuration, all of Scania’s Euro 6 diesel engines are already certified for a mix of up to 10 percent biodiesel.

More access to gas and torque

In September 2012 Scania launched two 9-litre Euro 6 certified gas engines with very high torque levels, allowing them to work in a variety of applications despite their moderate displacement.

With a drivability and range that is on par with diesel engines, Scania’s gas engines can be used for both local circuit distribution and long distance driving. And the range for a tractor can almost be doubled – from 600 km to about 1,100 km – with the help of tanks for liquid gas.

“There are high expectations at many levels when it comes to gas,” says Granath. “Bear in mind that by using biogas, it is possible to achieve a reduction in carbon dioxide emissions of up to 90 percent. So it isn’t surprising that the transport industry is turning towards gas in all its different forms.”

Lower noise levels

Compared with diesel engines gas engines emit much less noise making them suitable for use in urban areas where stricter noise regulations apply. Gas engines also qualify for tax benefits and local environmental incentives.

“Scania continues to invest in alternative fuel and offers an unprecedented range in the engine programme for Euro 6 regulations,” says Granath. “Thanks to this range our customers can choose from whatever fuels are locally available. Scania will continue to introduce many biodiesel, gas and ethanol engines along with our diesel engines. The aim is that all our customers should be able to find a solution regardless of application, and based on the local infrastructure for a specific fuel.”
