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.

New levels of efficiency and sophistication are being seen in the latest earthmoving machines coming to market - Mike Woof writes
The earthmoving equipment segment accounts for one of the largest parts of the total market for construction machines. All around the world excavators and articulated dumptrucks (ADTs) can be seen operating on construction sites. With a massive array of manufacturers offering these machines, it is no surprise that the segment is hotly contested. In developed markets firms are
Engine technology is advancing, with lower emissions, lower fuel consumption and longer service intervals being key developments - Mike Woof reviews some of the latest developments
A huge investment in diesel engine technologies in recent years has seen manufacturers develop low emission diesels that are quieter, cleaner and use less fuel, while in many instances delivering more power. For machine manufacturers this has been a major benefit, allowing them to meet tougher regulations on noise and exhaust
New engine emission regulations pose major challenges for engine manufacturers - Geoff Ashcroft reports. The arrival of emissions regulations in January for engines over 130kW has meant that engine makers have adopted varied technologies to meet and exceed those goals. For the end user though, buying new kit that complies with Tier 4 Interim/Stage IIIB emissions regulations is likely to carry additional costs.
