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 forthcoming Tier 4 emissions legislation represents a great leap forward in technology, Mike Woof reports
A high-profile focus on sustainability and reduced environmental impact is sweeping the construction sector in the European Union (EU) and the US. The EU and the US will implement regulations for the lowest emission off-road machines in history, with Canada and Japan expected to release similar regulatory programmes this year.
The legislation being introduced will transform the construction indu
The push towards cleaner-running driveline developments from engine firms is continuing - Mike Woof writes.
Sophisticated driveline developments are being seen right across the engine and drivetrain segment, with new low emission technologies being unveiled. High performance and extended service intervals are claimed, while tailpipe emissions have been reduced to meet the coming EU Stage V and latest US Tier 4 Final requirements. But different firms are taking different routes to delivering cleaner tailp
Volvo CE says that lowering fuel consumption will tackle fleet costs and deliver environmental benefits for its customers, Mike Woof reports. Volvo Construction Equipment (Volvo CE) is targeting fuel economy and performance with its latest generation of machines. The new L180F and L220F wheeled loader models are being fitted with the sophisticated OptiShift package, which will boost operation and driveline efficiencies and cut fuel consumption by 15%, and more in some instances.
Advances in asphalt plant technology will boost efficiency for producers, while increasing the percentage of recycled materials that can be used in the mix - Mike Woof writes. Asphalt plant technology continues to advance as the rival firms fine-tune their technologies for greater performance. New plants can give higher quality output due to new control technologies, while also allowing for recycled asphalt pavement (RAP) to be used more efficiently, while still ensuring tight mix specifications are met.
