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.

The new G9190 & G9220 VHP models are equipped with the firm’s automatic variable horsepower system. This is said to provide an automatic mode for transmission, allowing operators to shift between manual and automatic transmission. The system is also said to provide operators with greater control over the grading process while optimising fuel efficiency. In addition, the machines are fitted with a piston pump hydraulic system that is said to deliver the optimum oil flow to the hydraulic functions, regardless
