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.

Cummins has taken a major leap forward with engine design as it ditches cooled exhaust gas recirculation for its newest heavy-duty six-cylinder engine platform launched at bauma – the 12-litre QSM12. As its Tier 4 Final/Stage 4 engine solution in the 250-383kW sector, the QSM12 benefits from higher efficiency air handling and an advanced in-cylinder combustion process, allowing a return to using a straightforward wastegated turbocharger.
