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.

Earthmoving machines remain the backbone of construction operations - writes Mike Woof.
ADTs, excavators and wheeled loaders play pivotal roles in most construction jobs with the earthmoving stage providing a key component of most projects.
Tunnelling technology is seeing major developments that will boost construction efficiency - Mike Woof writes
Both in tunnel drilling and TBM systems, new machines are now being built that offer major gains in performance. Sandvik is introducing a number of major new models developments to its tunnelling drill range. Three new tunnelling jumbos are now available that suit different drilling requirements, the DD422iE, DT912D and DT922i.
The firm says that its advanced DD422iE rig offers major advantage
Key manufacturers are introducing new excavators and ADTs featuring the latest diesel engine technology, while there are developments too in the grader sector - Mike Woof reports
The start of 2014 was always going to be a key year for the construction equipment sector, given the commencement of the Tier 4 Final/Stage IV emissions regulations for North America and Europe. This phased introduction of ever tougher emissions regulations has been a long process, as well as a very costly one in terms of resear
