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.

Increased performance and more durable construction are key features of new generation excavators – Mike Woof writes. All the major equipment manufacturers are introducing new hydraulic excavators to meet market demand. These machines are offering increased output at the same time as producing lower emission levels and burning less fuel than before. From Caterpillar for instance comes its new 330F, which features a maximum operating weight of 29.75tonnes and is powered by a 178kW Cat C7.1 ACERT diesel that
Caterpillar’s new 390F hydraulic excavator uses a C18 Cat ACERT engine to meet the tough new Tier 4/Stage IV emissions regulations. The 92tonne 390F burns 7% less fuel at the same time as delivering more productivity than its 390D predecessor. Fuel-saving features include standard or economy power modes, to allow the operator to match operating speed to application.

One thing is clear in the concrete slipforming sector. This comparatively niche market for equipment is rapidly becoming a good deal more competitive as key manufacturers jostle for position.
