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 alternatives to diesel fuel as a power source continue to grow as firms move to cut emissions - Mike Woof writes. Only the most myopic could have failed to notice that times are changing in terms of engine technology. In the on-highway automotive sector as well as for the off-highway construction machine segment, manufacturers are looking to lower tailpipe emissions. Similar technologies have been employed in both on-highway and off-highway sectors, although those solutions have been adapted to better
The wide array of crawler excavators on the global construction market has led to strong competition between suppliers, each of which is keen to stay ahead of its rivals. All the major international manufacturers are introducing new models in North America and Europe for 2014, with key performance upgrades.
From Doosan comes the 22.5tonne DX225LC-3, which is said to offer increased performance and lower engine emissions and is aimed at one of the most highly competitive segments of the market. The machine
Technology advances for engine and driveline systems continue - Mike Woof writes
With the Stage V emissions requirements being introduced in Europe, a number of engine manufacturers have already announced their plans. Leading engine makers such as Cummins, Deutz, John Deere, Perkins and Volvo Penta have all released information regarding the engines that they will be offering.
The new standard introduces the particulate particle count (PN) and applies to all diesel engines above 19kW for off-road applic
Manufacturers are continuing to develop new excavators and wheeled loaders offering increased performance - Mike Woof writes. New developments are being seen in both the wheeled loader and excavator markets. Caterpillar, Daewoo, Hitachi, Hyundai, Komatsu, Kobelco and Volvo CE all have new wheeled loader or excavator models now available.
The segment for wheeled loaders has seen particular innovation from Caterpillar, with different machines being introduced for tightly regulated and lesser regulated mark
