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.

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
Major developments in soil compaction are being introduced - Mike Woof writes. With manufacturers keen to meet new regulations and deliver greater performance to customers, an array of new soil compactors are now coming to market. One of the new developments from the Ammann Group is the unveiling of its ASC 110 Tier 3 soil compactor, which is powered by a Cummins QSG 4.5 diesel rated at 119kW and has a 2.13m-wide drum. This machine is designed to meet the needs of emergent markets where high quality fuels w
Komatsu is now offering an updated version of its GD675 grader. The new generation GD675-6 benefits from an improved drivetrain with a dual mode transmission that is said to help to cut fuel consumption by up to 15%. In addition, the GD675-6 has the longest wheel base in its class and is said to offer a fine grading performance.
Power comes from a high-performance Komatsu diesel that delivers 163kW and is equipped with selective catalyst reduction (SCR) and AdBlue diesel exhaust fuel technology. This pa
