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.

Manufacturers of excavators and wheeled loaders continue to roll out new models aimed at specific markets - Mike Woof writes
With tough emissions controls now in place in Europe and North America, manufacturers have developed an array of advanced solutions to meet requirements, while also developing parallel models for sale in other territories. In the earthmoving sector the latest round of requirements in Europe and North America has resulted in a flurry of new, low emission models equipped with Tier 4
The SY500H model is the largest excavator offered by SANY in North America. Equipped with a powerful and efficient Cummins QSG 12 Tier 4 engine, this machine has the power to handle larger earthworks as well as pipelines, quarrying and mining.
Making its European debut is Komatsu’s D155AX-8 crawler dozer. Offering operating weights between 38 and 43tonnes, depending on machine set-up, the D155AX-8 has a patented SIGMADOZER blade which gives the machine a high blade capacity of 9.4m³. Komatsu claims that SIGMADOZER increases productivity by up to 15% over a conventional semi-u blade.
