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.

As the Perkins engine range continues to evolve, considerable upgrades have been made to offer more value to end users. One example is the Perkins 1204J-E44TTA, which now delivers up to 150kW, representing a 15% increase in power over its stage IV predecessor.
Perkins said that fuel consumption has been reduced by 5%, torque is up by 5-10% and the resulting improved characteristics of this 4.4 litre engine could enable OEMs to downsize without compromising on performance.
Doosan Portable Power was due to showcase its new compressor and generator products for the rst time in the UK in a special ‘Portable Power’ section of the Doosan Construction Equipment stand at Plantworx in Warwickshire, central England. The Stage IIIB compliant 9/305 large portable compressor and the G100-IIIA Stage IIIA compliant generator were set to be among the models at the 14-16 May 2013 show. The stand was also due to feature the new extended ‘Tough Top’ range of portable compressors and lighting
Chemical company Evonik has formulated an additive pack that creates multi-grade hydraulic oil for excavators. It is said to deliver a significant improvement in fuel efficiency compared to traditional mono-grade hydraulic oils.
It’s called Dynavis and the key, said Evonik, is a clever viscosity improver that prevents aeration, which can cause cavitation and a loss of performance in hydraulic pumps. Dynavis’ technology is a closely guarded secret - it is not available as a pour-in additive, but is sold in
