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.

Cummins said that Conexpo 2014 represents the biggest ever presence by the company at a construction equipment show, with over 29,828kW installed in more than 180 machines at the show. Its Tier 4 line-up on show extends from some of the smallest – the 55kW QSF2.8 installed in a carry crane from Manitex – up to the most powerful Tier 4i kit, that of a 738kW cold milling machine from Wirtgen which uses a twin-engine installation comprising QSL9 and QSX15 engines.

Changing the hydraulic fluid is not usually the first thought that comes to mind when looking to improve the performance of machines, but can in fact lead to up to 30% lower fuel consumption under extreme conditions, claims Evonik Industries. Hydraulic fluids featuring Evonik's DYNAVIS technology, such as those from Total and Indian Oil, are able to offer this and other benefits.
When compared with hydraulic equipment operating with conventional monograde hydraulic fluids, DYNAVIS-formulated hydraulic
The Finnish VTT research body believes that hydrogen offers considerable potential as a future fuel, according to its latest study. The Finnish hydrogen roadmap has been compiled by VTT Technical Research Centre of Finland and partly funded by the Finnish Funding Agency for Technology and Innovation (Tekes). According to VTT’s study, hydrogen fuelled vehicles will be as important as electric/battery types in minimising traffic pollution. The study says that transport applications for hydrogen are now close
