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.

The German construction equipment manufacturer's association, the VDMA, has stated that the new EU-exhaust emission directive presents a major challenge for its members.
New power generation systems are now coming to market that offer lower emissions and cleaner options for customers. Engine technology has improved enormously in recent years, with exhaust emissions from industrial diesels having been reduced significantly. Meanwhile, manufacturers have also introduced new systems that can further reduce emissions while retaining output and performance.
The introduction of the latest emissions standards in North America and Europe are requiring major design rethinks for earthmoving machines such as ADTs, Mike Woof reports. With the introduction of the Tier 4 Interim/Stage IIIB emissions legislation, major changes are being made to off-highway machines. One of the machine types most affected by this legislation will be the articulated dump truck (ADT) and designers have faced major challenges in developing solutions that retain what are now seen as key oper
Articulated dumptrucks are highly versatile and new developments continue to extend productivity The ADT market has been one of the fastest growing product areas in recent years. In the past ADTs were niche products that sold particularly well in Northern Europe (and Scandinavia and the UK in particular) as well as South Africa for many years, but these have now become popular worldwide. The number of manufacturers in the market has grown too. Just 10-15 years ago the only serious ADT manufacturers building
