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 market is seeing new wheeled loader and excavator models coming to market, including some radical new designs - Mike Woof writes. The global market for earthmoving machines is seeing some important developments. Manufacturers are now offering separate machines for customers in developed and developing markets. Meanwhile there are also some innovative concepts being made available. One of the most notable new earthmovers is the innovative VL70A vertical lift wheeled loader from LiuGong. This model featur
High engine power combined with reduced fuel consumption are said to be key qualities of Doosan’s new DL200-3 and DL250-3 wheeled loaders. Both new models are also said by the South Korean firm to provide better operator comfort, exceptional performance, ease of handling, easier serviceability and extended durability. The wheeled loaders’ new cab design is said to offer greater visibility thanks to a wider front glass section and an extended wiper blade area. Now that the reservoir for the wiper water is l
After launching its biggest turbocharger, the 900-series, Cummins used CONEXPO-CON/AGG to introduce its smallest.
Badged the 100-series, this back-to-basics design features a boost-controlled pneumatic wastegate, and is said to be suited to engines operating all variation of after-treatment system.
The latest developments in drilling rigs can help boost efficiency in quarry producion applications - Mike Woof reports. Efficient drilling and blasting operations can have a huge impact on production costs in quarrying. Accuracy of hole direction and depth, as well as optimum blast design and explosives use, are critical for efficient blasting work. Ineffective blasting can result in high quantities of fines of low commercial value as well as over-sized material requiring secondary breaking. This impacts o
