Turbocharger package cuts emissions and boosts fuel efficiency
Cummins’ latest turbocharger innovation has been extended to the 500-series, with an electronically wastegated turbocharger that delivers efficiency gains of up to 8% as a result of changes to the exhaust turbine. By more closely matching turbine wheels to the compressor, greater fuel efficiency is achieveable, said the firm. The 500-series turbocharger is also said to offer improved resistance to oil leakage by 200% over the current industry standard.

2011 has already seen a host of new machine introductions among compact equipment makers, and we take a look at some of them in the utility sector
With emissions legislation dominating the introduction of new machines over 130kW, smaller equipment has not been overlooked. Most firms have been working feverishly to produce quieter, more economical and more productive equipment and Japanese maker Takeuchi is a good example, having recently introduced a new 8.5 tonne midi excavator.
Cummins is now commencing testing of hydrogen-fuelled internal combustion engines, while also entering into a partnership with oil firm Chevron for the supply of hydrogen
The latest developments in asphalt compaction equipment will help boost productivity and finish quality. The new generation compactors can utilise the latest generation machine control tools to deliver quality within the short timeframe determined by the asphalt temperature. Ammann has broadened its asphalt compaction range with the addition of the new ARP 95 K pivot-steer roller and the articulated ARX 90 and ARX 26 models. These units are available with Ammann’s proprietary ACE compaction systems to optim
