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 Emissions Solutions, the engine manufacturer’s specialist after-treatment division, has developed a single-unit DPF-SCR module concept that is 60% smaller and 40% lighter than its current two-box solution. The EcoFit single module has been designed to work with Cummins’ Stage V engines when they arrive in 2019. “We could achieve Stage V with our current DPF-SCR system, however Stage V is an opportunity to take this technology further,” said Richard Payne, Cummins’ off-highway regulatory affairs dire

Rolls-Royce has received its first order for large industrial diesel engines from a customer in China. The order is for Series 4000 MTU engines, which meet the Tier 4 Final emissions regulations. Key customer Jereh Petroleum Equipment has ordered 16 of the MTU 12V 4000 T95 diesels for industrial purposes. The company intends to sell the equipment which fulfils EPA Tier 4 regulations on the US market. The contract was signed between Jereh and MTU with MTU’s Oil & Gas distributor in China, China Diesel Suppor
Hyundai Construction Equipment says that its innovative HW155H hydrogen fuel-cell-powered, wheeled excavator is showing the industry how hydrogen could contribute to future carbon-free operation on construction sites. Digging and driving performance is said to match that of conventional diesel-driven machines.
The firm is leading the field with its radical zero-emission solution and according to a company spokesperson, “This machine is not a prototype any more. It is production-ready. But the market is not ready for it yet.”
