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.

Subaru’s new ER12 Rammer Engine is said to feature a carefully balanced and engineered design, and is exclusively intended for the demanding application of rammers.
With specially-designed components and overhead cam (OHC) technology, the 3hp, four-stroke engine is lightweight, yet rugged and powerful. Weighing in at around 9.07kg, the ER12 is said to offer more power and up to 24% more output than similar competitive engines, all while being lighter in weight and designed for optimised balance and perfo
Advances in drive technology are being seen from several key firms as new generation, compact electric systems begin entering the market - Mike Woof writes
Major innovations in machine systems are being seen in the construction equipment sector. Several manufacturers are hedging their bets with regard to drive technology and introducing electric drive machines, which will suit use in urban ultra-low emission zones.
Wacker Neuson has developed an array of electric machines in recent years including a numbe
LiuGong unveiled new machines as well as its plans for the future at the BICES 2015 construction equipment show in Beijing recently. Trading conditions are tough in China at the moment, but LiuGong is performing better financially than many of its local rivals according to the firm. LiuGong’s vice-president, Dave Beatenbough said that the firm is particularly well known for its wheeled loaders, a product line for which the firm is a market leader in China. However, he explained that the company is actively
Paving machines vary considerably in North America compared with those units used elsewhere. On a worldwide basis, pavers with tamper bar screeds are popular having been developed in Europe and also favoured by Japanese and Chinese firms. But in the US the length of highways to be constructed resulted in a focus on high production pavers, which still continues today. North America and Latin America are key markets for these machines, with Australia being one of the few territories to employ both European an
