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.

Driveline technology continues to develop rapidly, with many manufacturers at this year’s Conexpo exhibition showing Tier 4 Final emissions solutions, along with a host of fuel saving transmissions and hydraulic systems, all aiming to reduce operating costs for the customer. However, while there was certainly a hybrid presence at the show, things haven’t perhaps moved forward as fast as many had expected.
The excavator remains the key earthmoving tool, Mike Woof reports. The versatile hydraulic excavator has been at the heart of most earthmoving projects around the world for many years, a dominance that looks set to remain. Because of the importance to the construction sector of the excavator, manufacturers are keen to upgrade and improve their competing machines on an almost continuous basis. New technology proliferates in hydraulic excavators while firms are also focussing on increasing the range of tasks
Hatz has boosted diesel engine efficiency with an all-new four-cylinder 2litre platform that combines low weight with low fuel consumption and meets Tier 4 Final/Stage IV emissions regulations without the need for a DPF.
Called the 4H50TIC, the new engine uses two-valve cylinder head design to cut frictional losses, while opting for lower injection pressures of 1,800bar to contribute towards improved fuel efficiency.
