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.

Both machines are powered by Doosan’s DL06K ‘common rail’ six-cylinder turbocharged diesel engine, said to meet Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. The engine has a displacement of 5,890cm³ and is said to deliver 15% more power [82 kW @ 1850RPM] than previous Stage IIIA models. The engine also delivers 11% more torque (49.5kgf.m) in the DX160LC-3 model. Doosan said that factory tests had
Kobelco Construction Machinery Europe (KCME) says the SK210HLC-10 is a “revolutionary hybrid [excavator] that delivers the future today”. The SK210HLC-10 is also said by KCME to be the first true hybrid specialist excavator in the 21tonne operating class. Drawing on over 80 years of Kobelco design, technical innovation and manufacture, the Japanese company has been at the forefront of hybrid technology since 1999, when work on hybrid excavators began. With the new SK210HLC-10 and the introduction of its
A new generation of asphalt compaction technology is coming to market, reports Mike Woof. The market for rubber tyred compactors has grown in recent years, prompting manufacturers to develop a new generation of machines.
