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.

The innovative QBREAK electric car is to benefit from a sophisticated methanol fuel cell range extender. Development work is being carried out on the project by a consortium of Danish companies. The plan is to develop a novel, range-extended electric vehicle that uses biomethanol as a fuel source. TheModularEnergyCarrier concept (MECc) project has just been granted funding from the Danish government. The reworked electric car is expected to deliver high market potential due to a competitive price and specif
International construction equipment manufacturer Chicago Pneumatic has introduced versions of its CPS 11.0 (7bar) and CPS 11-12 (12bar) portable compressors aimed at the European market. The compressors feature Deutz EU compliant Stage 3B engines and are meant for surface drilling, abrasive blasting and ice blasting and excel in road work and shotcrete pumping. The 12bar variant is also suitable for special applications such as fibre optic cabling. The higher working pressure enables the CPS 11-12 compress
New generation bulldozers are coming to market that are more powerful, more productive and more efficient. Both Komatsu and Liebherr are upgrading and expanding their model ranges at present for example.
From Komatsu Europe comes the highly efficient D61EX/PX-24 dozer, which is said to be highly versatile and able to carry out a wide array of grading or earthmoving applications. Improved features include an upgraded cab and a new automatic idling engine shut down system. Proven features from the earlier
