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.

John Deere intends to use a package of technologies in its new diesels to achieve the low emissions performance required for Tier 4 Final/Stage IV compliance in the US and Europe. The regulations maintain the strict particulate matter (PM) emission levels established by Interim Tier 4/Stage III B regulations, while requiring an additional 80% reduction in nitrogen oxides (NOx). To meet Final Tier 4/Stage IV emissions regulations in some power categories, John Deere has developed what it calls the Integrated
Major manufacturers continue to develop new soil compactor models - Mike Woof reports. Innovations in machine design are being seen in the soil compaction sector from a number of major firms. As in other equipment sectors, new engine emissions legislation has played a huge role in driving the latest design changes. Europe, the US and Japan are rolling in the new Tier 4 Final/Stage IV legislation on noise and exhaust emissions which will be phased in across power output classes from the start of January 2014
The new four cylinder 3.4 litre diesel from Perkins Engines completes the firm's Tier 4 Interim/Stage IIIB product line-up. The 854 Series is said to offer improved power density in a compact package to suit an array of applications. This engine comes in addition to the 1200 Series, which was recently introduced.
Scottish firm Land-Drill Geotechnics is now using four new Ingersoll Rand 17/235 portable compressors to provide compressed air for the company's fleet of drilling machines. Land-Drill is an independent, management-owned company, offering geotechnical and geo-environmental investigations, laboratory testing and advice to the construction industry. With the new 17/235 compressors supplied by Doosan Infracore Portable Power, Land-Drill has added machines that are more compact than previous compressors used by
