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.

Up to a third of fuel consumption in cars is is spent in overcoming friction. However, both fuel consumption and emissions can be reduced by the use of new technology. This news comes from a joint study by the VTT Technical Research Centre of Finland and the Argonne National Laboratory (ANL) in USA.
Innovative new technology can reduce friction by anything from 10-80% in various components of a car according to the study. And it should be possible to reduce car fuel consumption and emissions by 18% withi
New technologies are coming to market with regard to driving and supporting tunnels, with drilling and blasting and accompanying shotcreating technologies being widely used worldwide. Drilling and blasting can be a cost-effective method in the right conditions and in this segment Atlas Copco and Sandvik hold major market shares worldwide, although other firms such as Furukawa and Montabert also compete. Shotcreting equipment is widely used following after drilling and blasting, with CIFA broadening its rang
A leading UK civil engineering firm has hailed the fuel efficiency of JCB’s new tier 4i tracked excavators.
Surrey-based J Devine Group has just purchased three JS130 models and is already impressed by the machines’ fuel efficiency and reliability on its housebuilding projects.
