Scania bulks up
SCANIA AUSTRALIA has used Melbourne’s International Mining and Resources Conference to give the national transport industry its first local look at the XT bulk haulage range.
Available in three cab sizes, the XT comes with safety features available to its highway siblings, such as side curtain rollover airbags as standard in its choice of P, G and R-series Day Cab.
The XT is available with a full range of Scania’s “frugal and modular” Euro 5 or Euro
6 SCR emission engines and Opticruise automated gearchanging, including the clutch-ondemand feature “for particularly challenging environments”.
Engine configurations include five-cylinder nine-litre, six-cylinder 13-litre engines or the V8 16.4-litre.
Scania has switched to the lighter, less complex SCR-only exhaust aftertreatment (with the exception of the top of the range, highest-output V8 730hp (544kW) engine which uses a combination of EGR and SCR).
“Specific changes to the nine-litre five-cylinder engine include new engine software and a reconfigured combustion chamber,” it says.
“One important change is that oil cooling is now thermostatcontrolled. This contributes a 1 per cent fuel saving, since the oil can generally be allowed to maintain a higher working temperature. The cooling fan is fitted directly on the crankshaft and no energy-intensive upshifting is required.
“Other modifications that help to reduce consumption are an increased compression ratio (from 18.0:1 to 19.0:1), a cylinder pressure increased to a maximum of 190 bar (180 bar for the 280hp [209kW] version) and a more efficient combustion chamber.
“The nine-litre family shares its technology and design with its sixcylinder siblings in the 13-litre in all material respects.
“Its balance shafts and the introduction of an asymmetric crank pin pitch counteract the tendency of five-cylinder engines to vibrate, so that it now runs just as smoothly and silently as a sixcylinder engine.”
All of Scania’s Euro 6 diesel engines are already certified for a mixture of up to 10 per cent biodiesel in their basic configuration, without any impact on maintenance requirements.
Highlights the truck maker identifies is the XT’s protruding steel front bumper, headlamp protection grilles, front underbumper skid-plate, 40-tonne towing point in the centre of the bumper, and robust door mirror housings, as well as an elevated ride-height and all-steel parabolic leaf spring suspension.
