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.

In what could help fuel widespread adoption of natural gas-powered (NG) vehicles in the US and globally, GE researchers, in partnership with Chart Industries and scientists at the University of Missouri, have been awarded a programme through Advanced Research Projects Agency for Energy (ARPA-E) to develop an affordable at-home refuelling station that would meet ARPA-E’s target of $500 per station and reduce re-fuelling times from 5-8 hours to less than 1 hour.
Singapore-based PRIMACH is now offering an improved range of small to medium sized batching plants. These units are designed to meet the needs of developing markets and can cope with use in remote areas with tough jobsite conditions. Rugged and reliable, the plants can cope with wide variations in climate, while producing high quality hot-mix at low cost according to the firm.
The PRIMACH asphalt mixing plants have been specifically developed to meet customer needs in emergent markets such South East Asi
Manitou has extended its Easy machine options to cover machines up to and including the 18m class MT1840. The company said that the move follows the introduction of an Easy version of its very popular MT625H compact telescopic handler. Manitou’s new MT732 to MT1840 Easy telehandlers meet the Stage IIIB emissions requirements by using a 55.4kW Deutz TD36L engine with a Diesel Oxidation Catalyst (DOC). Importantly, this engine does not require a DPF (Diesel Particulate Filter) or the use of a Diesel Exhaust
Case Construction Equipment reports that all four of the manufacture’s 67kW compact skid steer loaders and compact track loaders now achieve Tier 4 Final compliance.
Case also says that a number of detail enhancements have been made across the range of nine skid steer loaders and four tracked loaders. Selective catalytic reduction (SCR) and cooled exhaust gas recirculation solutions improve fuel efficiency, keep exhaust temperatures down, remove the need for exhaust gas recirculation and eliminate the need
