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.

Atlas Copco has completed the introduction of its fifth generation soil compactor range with the roll-out of the compact CA models. The new Dynapac CA1300 and CA1500 machines share features with the larger machines launched earlier this year, with a focus on reduced operating costs, low operating noise and fuel consumption and ease of servicing.
German engine firm Hatz says that its latest 3H50T diesel offers a compact power package for use in European Stage V emissions compliant machines. This is the newest addition to the H series and is a three-cylinder diesel that is said to offer high torque and EU Stage V compliance. The 3H50T is available in the Fan-to-Flywheel version as well as in an open power unit (OPU) variant. The new engine competes in the class for under 19kW units and extends the product range of H-series engines. It has a
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.
