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.

Increasing asphalt plant sophistication will boost the capabilities for the use of recycled materials - Mike Woof writes Major innovation is being seen in the asphalt plant sector with many of the major manufacturers developing sophisticated new plants. The increased use of recycled materials and reduced fumes emissions are all important issues for the segment. In the US for example, the potential for recycled asphalt has been well identified. It is now one of the most frequently recycled industrial materia
Emissions remain the focus for engine development but equipment manufacturers want clarity from regulators. Emissions remain a major challenge for the off-highway construction equipment market. The EU has tough targets in this respect and its objective is an overall reduction of CO2 emissions of 80-95% by the year 2050, compared to 1990 levels. There is considerable research already underway on how to reduce fuel consumption and to help ensure the security of energy supply. A number of industry sectors, suc
Perkins has completed its line-up of four-cylinder engines for Tier 4 Final/Stage IV with the introduction of the 854F-E34TA – the latest in its 800 Series range. The compact, four-cylinder, 3.4litre engine incorporates specially developed SCR technology for the first time. Packaged separately from the DOC module, it can be mounted in either a horizontal or vertical position, giving OEMs of compact machinery greater installation flexibility in the engine bay.
