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.

Innovative asphalt compaction machines are now being introduced by several of the major manufacturers, with solutions offering improved working efficiency and performance.
Three of the most innovative developments for asphalt rollers come from Dynapac, BOMAG and Hamm, although new asphalt compactors are also being introduced by other firms such as Ammann and Caterpillar.
Advances in asphalt compaction are offering improved performance right across the spectrum of size and capacity – Mike Woof writes. New asphalt compaction machines are offering major gains in performance as firms develop new systems. Large and small asphalt compactors now offer higher output than earlier generation machines, while delivering better quality and lower fuel consumption as well as gains in reliability, durability, safety, ergonomics and operator comfort.
New technology broadens Sandvik's offering for crushing and screening. Mike Woof reports Sandvik is making a series of upgrades to its crushing and screening line in jaw and cone crushers as well as wear parts, and these should suit an array of applications ranging from small recycling operations up to large quarry sites. At the more versatile end of the range is the new CJ208 jaw crusher, the latest addition to the CJ200 series jaw crusher line-up. This crusher is the smallest of the CJ200 Series and offer
High performance and productivity are claimed for the new generation DL200-3 and DL250-3 wheel loaders from Doosan Infracore. Powerful engines and a number of new features help reduce fuel consumption while these machines are also said to be easier to service and offer extended durability. The new cab design provides better visibility and more leg room, while it has a new instrument panel with an integrated VCU (vehicle control unit).
