Cummins has unveiled its Stage IIIB compliant 8,9 litre QSL9 engine platform at Intermat, designed to replace the current 8,3 litre QSC engine.

The QSL9 increases top-rated power to 283 kW with peak power rising to 298 kW. This compares to 272 kW of top-rated power and 280 kW of peak power found in the current Stage IIIA compliant engine. The company also expects a -5% reduction in fuel consumption, depending on rating.

"Our Stage IIIB engines are the first phase of our Stage IV answer," said Steven Nendick, European communications director. "It's important for OEMs to consider both Stage IIIB and Stage IV as a package because our Stage IIIB solution comprises most of the major engine work that will form the basis of our Stage IV engines in due course."

A fully integrated air-intake to exhaust after treatment system, Cummins' new engine features XPI extra-high pressure common rail injection, an integrated Cummins particulate filter and cooled exhaust gas recirculation (EGR).

"We've already completed over 100 Stage IIIB installations," Mr Nendick told CE at Intermat. "Our pilot centre in Darlington, UK is currently testing these installations across a range of construction equipment and thus far we've not encountered any real issues."
