New Euro 6 Engines From Scania


As part of a busy rollout of new products, Scania is expanding the number of Euro 6 engines available for its Next Truck Generation vehicles.  The company’s 9 L engines now come in five different variants, with two intended for use with fatty acid methyl ester (FAME) biodiesel.

Also joining the lineup is the final member of Scania’s 13 L range, the DC13-149, rated 370 hp (276 kW) that utilizes a Miller camshaft with a special profile that keeps the intake valves open longer. This is used to help keep engine temperatures at a sufficient level to allow the selective catalytic reduction (SCR) aftertreatment to operate effectively without the need to add fuel to raise the exhaust temperature.

Scania has launched a series of new Euro 6 diesel engines, including the 9 L DC09 diesel (top) and the 13 L DC13.

Scania now has 12 Euro 6 truck engines in production, all of which share a modular design approach. The latest generation of Scania’s modular designed DC09 9 L, inline five-cylinder power unit comes in three different power ranges – 280 hp (208 kW), 320 hp (238 kW) and 360 hp (268), all at 1900 rom. All of the Euro 6 engines also incorporate new engine management software and upgraded combustion chambers.

Oil cooling is now thermostat-controlled, which delivers a 1% fuel consumption saving because the oil can now be kept warmer even when there is a lower power output and lower external temperatures, Scania said. Additionally, the larger diameter cooling fan is mounted on and directly driven by the crankshaft, thus consuming less power, Scania said.

In a separate announcement, Scania said it also introducing a new generation of Euro 6 V8 engines available at 520 hp (387 kW), 580 hp (432 kW) and 650 hp (485 kW) at 1900 rpm. The new V8 engines can reduce fuel consumption by 7 to 10% for customers with vehicles that have higher combined truck and trailer weights, higher average speeds, or both, the company said.

Scania said the new engine generation is its response to the growing trend in the transport industry towards heavier, longer trucks and marks a new highpoint in the company’s engine building.
