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 and improved mobile crushing and screening equipment is focused on delivering cost/tonne reductions in aggregate production - Geoff Ashcroft reports. The level of technology being applied to mobile crushing and screening systems continues to advance, which is indicative of manufacturer confidence in this sector as one that continues to offer an economic benefit. An example of how electronic technology can lead to greater productivity can be found with KPI-JCI - the firm has introduced a high resolution
Komatsu’s upgraded D155AX-8 crawler dozer meets Tier 4 Final requirements and is powered by an SAA6D140E-7 engine rated at 264kW. Not only does the engine produce lower emissions, it is also said to be more productive, dependable and efficient, with lower fuel consumption and better response.

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.
