Tribology within Turbochargers

Novel Solutions for Materials Engineering Increased demands are being placed upon turbochargers as a result of ever more stringent emissions regulations, a necessity for improved product performance and reliability and a requirement for a wider product operating range. Consequently, a greater level of stress is placed upon the materials from which turbochargers are manufactured. In order to achieve all of the necessary legislation and customer requirements, novel solutions to materials engineering challenges are being developed.

Embree has worked in Cummins Turbo Technologies as General Manager – Asia, since July 2011. She replaces Jim Lyons, who was named the Company's Vice President and Chief Manufacturing Officer in November.

The Engine Waste Heat Recovery Research Programme, which received funding through the Regional Growth Fund in October 2011, is now developing and testing a next generation, green technology that recovers wasted heat from various points of the engine, and uses it to increase overall efficiency. The extra power can be channelled into useful electrical (5kWe) power in the engine system, replacing alternator systems and aiding significantly growing electricity requirements in modern trucks.

The turbocharger engineering firm has been named Company of the Year and Engine Test Facility of the Year in the annual Automotive Testing Technology awards, which is a non-profit-making enterprise designed to highlight and reward the efforts of individuals and companies who have made a difference in the world of vehicle development.

The extensive range, set to make its European debut at INTERMAT (20-25 April 2015), provides robust flexible solutions for the off-highway sector. The launch will allow Cummins Turbo Technologies to bring to market the most efficient turbochargers in the heavy duty range with new technologies capable of improving overall turbocharger efficiency by up to 10%.*

The Holset turbocharger was designed and tested at Cummins Turbo Technologies European Technical Centre in Huddersfield, West Yorkshire. The testing verified the durability of the product, to meet many differing duty cycles including that of a city bus. This testing also achieved excellent results in performance, quality, and safety.

The launch will allow Cummins Turbo Technologies to bring to market the most efficient turbochargers in this range with new technologies capable of improving overall turbocharger efficiency of a typical application by up to 10%. The announcement, being made at CONEXPO 2014, follows the company’s unveiling of a range of products for the off-highway market earlier this year at BAUMA 2013, and marks its continued commitment to the sector.

Cummins Inc, a corporation of complementary business units that design, manufacture, distribute and service diesel engines and related technologies, has signed-up a group of women identified as prospective business leaders of the future to An Inspirational Journey's Pearls programme. The Pearls programme is an initiative that already reaches out to more than 4,000 women from a multitude of sectors and regions across the UK, and comprises of women who have been identified as future business leaders.
