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.

Solutions for Tier 4 Final emissions regulations dominated Conexpo 2014, with many firms showing off their options of DOC, DPF and SCR after-treatments. Deutz, while staying with an SCR-only solution, took a more unusual approach on its high horsepower V6 12litre and V8 16litre engines. Both get a dual SCR after treatment system to meet Tier 4 Final emission standards.
Stricter emissions legislation mean that new engine technology and integrated drivetrain systems are being developed. With the Tier 3/Stage IIIA emissions legislation now in place in North America and Europe, the major engine manufacturers already have an array of solutions on the market. The coming Tier 4 interim/Stage IIIB legislation will be tougher still and most firms are well in hand with their plans to use both in-cylinder and exhaust after-treatment technology. While engines themselves are staying b

There has been strong pressure against internal combustion engines worldwide, with the scandal over the emissions from diesel powered private cars has strengthening opinion against these engines. Diesel engine firms are taking the long view by offering future power options such as alternative fuels and electric systems. The engine builders are also hard at work ensuring that power units for the indust
