Scania is expanding the number of Euro 6 engines available for its next truck generation.
The company’s nine-litre engines now come in five different variants, with two intended for use with FAME (fatty acid methyl ester) biodiesel.
Also joining the line-up is the final member of Scania’s 13-litre range, the DC13-149, which has 370PS and a Miller camshaft.
Scania now has 12 Euro 6 truck engines in production.
The latest generation of Scania’s modular-designed DC09 nine-litre, in-line five-cylinder power unit comes in three different power ranges: 280PS, 320PS and 360PS.
New features include 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.
Additionally, the cooling fan now has a larger diameter and is mounted on and directly driven by the crankshaft, meaning it consumes less power.
A shared feature among the entire nine-litre range is that they rely exclusively on fixed geometry turbos.
As a result they only use selective catalytic reduction (SCR) for exhaust gas after-treatment. In the case of the 280 engine, the improvements that have been made to its after-treatment system have reduced to a minimum the need for stationary regeneration to clean the particle filter.
The introduction of the new DC09 nine-litre range also sees the arrival of engines that can be specified for use with alternative fuels – the DC09 320 and the DC09 360.
Both can be specified to run on either diesel or 100% FAME (such as rapeseed methyl ester) or any blend of the two fuel types.
Another engine now making an appearance in Scania’s engine range for the new generation of trucks is the 13-litre, 370PS DC13.
The DC13 370 features a new engine management system and reworked cylinder heads. It also now relies upon a fixed geometry turbo and SCR-only.
Scania says these improvements lower fuel consumption by about 4% under typical driving conditions, while the new configuration of the engine has also been equipped with a Miller camshaft.
