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.

Caterpillar has re-engineered its 7litre C7.1 engine to create a power unit more suited to those markets with lesser-regulated emission controls. Meeting China Stage II emission regulations – equivalent to EU Stage IIIa/EPA Tier 3 – the C7.1 uses high-pressure electronic common rail fuel injection and a wastegated single turbocharger, to achieve a power output of up to 205kW.
All-wheel-drive trucks for the Chinese market - Mike Woof reports. One noticeable development at the bauma China exhibition in Shanghai in late 2012 was the proliferation of ADT models. Doosan and Volvo showed some of their latest ADT variants alongside their latest excavators and are keen to highlight the benefits of ADTs for use on sites where traction or grade may be an issue for rigid trucks or on/off highway haulers. However Caterpillar chose to highlight its off-highway rigid trucks at bauma China, as
