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.

LiuGong’s 856H wheeled loader with “new LiuGong DNA” is being showcased at INTERMAT 2015 for the first time in Europe in Tier 4 Final/Stage IV configuration. “The H-Series [wheeled loaders] has been completely designed to work efficiently, and to be easy to service and maintain,” said David Beatenbough, LiuGong’s vice president. “This is the first machine to display our new LiuGong DNA. Over the coming months and years you’ll see machines with the same visual cues as the 856H.”
In the more down to earth market for crawler excavators, some novel developments are coming to market. Case is upgrading two key mid-weight crawler excavator models.
Utility machines with standout efficiency and cutting-edge cab design have come onto the market during the first few months of 2013. Guy Woodford looks at some of them. Case Construction Equipment and New Holland Construction have brought out what they claim are the market’s first Tier 4 Final emissions standard midi-excavators. The CX75C SR and CX80C models from Case are said to offer more performance power and greater operator cabin comfort than previous models. Tier 4 Final standards are said to have bee
LiuGong is introducing new Tier 4 Final/Stage IV compliant versions of its 925E and 933E excavators during 2016. These are being built in its factory in Poland and benefit from patented turbocharging technology developed by Cummins, optimising power and minimising fuel consumption. This system is said to vary varies airflow to match engine and load demand. The low speed, high output torque engines are specially designed for the E-series excavators, while the machines also feature innovative negative flow hy
