On the engine front, none had bigger news than Cummins, and there were plenty of willing listeners when Mike Fowler, Cummins South Pacific director of engine business, announced that both the 15-litre X15 and 12-litre X12 engines will meet the proposed Euro 6 emissions standard without any EGR input. While the Euro 6 standard may be still several years away from being mandated in Australia, Cummins used the Brisbane show to ease customer fears of increased complexity.
“We are giving customers confidence that the X15 they have now will be very similar to the X15 they will have for Euro 6,” Fowler explains, citing SCR (AdBlue) technology and a new single-module after-treatment system as the keys to Cummins’ strategy for Euro 6. As for the X12, formerly known as the ISG12 and said by Cummins to have the best power-to-weight ratio of any engine in the 10- to 16-litre class, it will also rely on SCR and advanced after-treatment to counter the need for any EGR input.
Rated up to 500hp (373kW) and 1700lb-ft, the X12 is a highly promising engine which has yet to find a chassis to call home in Australia. However, the quiet word at Brisbane was that one truck brand is close to signing up. Meantime, there’s much to be gained by the announcement of closer technological ties between Cummins and transmission giant Eaton. In a smart move for the two brands, it’s an arrangement which mirrors the successful European strategy of looking at engine and automated transmission development as a collective exercise rather than separate functions.
