Sca­nia bulks up

Owner Driver - - Tech Briefs -

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.
