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.

Caterpillar has introduced the next generation of articulated trucks, with the new B Series models, which now include the 735B, offering a 32.7tonne payload; the 740B (39.5tonnes), and the 740B EJ with ejector body (38tonnes).
Chinese firms are continuing to invest in their dozer ranges, particularly Shantui and XCMG. Shantui has now achieved full CE certification for its SD13YE model bulldozer, with this having been awarded by the German certification agency TUV Rhineland. During its prototype stage, the SD13YE was subjected to rigorous testing, after which the machine was sent to TUV Rhineland for inspection. After its own thorough inspection the agency found the SD13YE compliant with EC requirements and granted the machine th
DEUTZ has been highlighting its innovative diesel and gas engines meeting the China Nonroad Stage IV emissions standard set to come into force in 2020 – along with its latest developments in electric drives.
Effective exhaust aftertreatment for its engines is one of DEUTZ’s core competencies. The German headquartered global market firm was the first manufacturer in the world to be certified for the EU Stage V emissions standard coming into force in Europe in 2019. DEUTZ already successfully uses the necess
