Cummins has taken a major leap forward with engine design as it ditches cooled exhaust gas recirculation for its newest heavy-duty six-cylinder engine platform launched at bauma – the 12-litre QSM12. As its Tier 4 Final/Stage 4 engine solution in the 250-383kW sector, the QSM12 benefits from higher efficiency air handling and an advanced in-cylinder combustion process, allowing a return to using a straightforward wastegated turbocharger.

CNH Construction marketing director Jean-Patrick Yekpe has highlighted the money-saving potential of Case Construction Equipment’s new midi-excavators, unveiled at bauma 2013. The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system. “When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of thi

JCB says its Ecomax Stage 4/Tier 4 Final engine can be engineered into many existing machines without needing additional space by using a ‘one can’ selective catalytic reduction (SCR). According to the company’s chief technology officer, Tim Burnhope, in many cases the mini SCR on the Stage 4/Tier 4 Final Ecomax engine can be positioned in the same space occupied by the exhaust silencer on previous generations. He said, “Our engine is already so clean that we only need 2% to 3% of urea, which allows us to u

Skako Concrete has – literally – unveiled its new Rotoconix mixer after keeping the new model under cover until 11am on the first day of bauma. The Rotoconix is designed for quick batching cycles, fast discharge and uniform mixing no matter the batch size. The mixer has three key parts, all of which are reversible. It combines a rotating cone a high-speed ‘turbo whirler’ and a screw.

After two years of research and development, attachment manufacturer Simex has launched the VSE 40, a screening bucket with a patented mechanism that allows the operator to change the size of the screened material from the cab at the touch of a button. All similar products require eight to 10 hours’ work to change the setting, according to Simex’s assistant general manager Fereico Tamburri. “After we introduced our crushing bucket, we visited lots of crushing sites and found out that for all the screening b
