Developing Next Generation Innovations to Improve Diesel Engine Efficiency

Highly Durable, Highly Efficient and Compact Turbochargers Are Becoming Increasingly Desirable
Over the past few years, the market has seen global engine and vehicle manufacturers shift their focus from emission driven regulations to fuel economy improvements to insulate their customers from rising fuel prices. With fuel prices remaining high, Cummins Turbo Technologies is committed to focusing on developing next generation technologies to improve diesel engine efficiency. This trend in engine downsizing, in parallel with both engine and vehicle manufacturers striving to maintain or increase the power outputs from their products, is proving an engineering challenge.

Working Together
Working in partnership with many engine and vehicle manufacturers Cummins Turbo Technologies can offer bespoke products and versatile solutions using our global expertise and market knowledge. These close working relationship have informed the research and development that is shaping our future product range, leading to the creation of a new generation of technologies. We don't simply provide off-the-shelf products, we develop advanced technological solutions that are 'fit for market', in partnership to meet customers' specific requirements.

Next Generation Innovations
Cummins Turbo Technologies recently unveiled at IAA Hannover 2014, a selection of next generation innovations capable of improving the fuel efficiency of modern diesel engines by at least 10%, whilst also giving the customer a diverse range of technical options to help achieve the next stage of legislation.

Next Generation HE300VG
Variable geometry turbochargers provide optimum power output with efficient fuel consumption. This next generation HE300VG design has been enhanced specifically to improve efficiency, and its features and benefits include:

• Improved turbocharger efficiencies of up to 12% enabling improved fuel efficiency and reduced CO2
• 10% lighter than its existing counterpart creating greater fuel economy
• Enhanced integration with the engine system due to a new actuator
• Improved durability and optimized performance through the patented moving shroud variable geometry mechanism

Holset M2 Two Stage Systems with Rotary Turbine Control (RTC)
This bespoke technology sits within our specialist Modulated 2 stage (M2) product range and has been developed in partnership with the Cummins Engine Business Unit. The RTC technology is used to channel exhaust to the required areas for complete exhaust control capability. Its features and benefits include:

• Enables our customers meet performance levels whilst still meeting stringent emissions target within light-duty market
• RTC helps enable air flow range to reduce turbo lag whilst maximizing horsepower range
• Optimized Aftertreatment operating conditions for emissions control
• RTC enables thermal management control for exhaust regeneration functionality

Electric Waste Heat Recovery Turbine Expander
This prototype captures what would otherwise be lost energy, in the form of heat. It turns this into useful electrical (5kWe) power that is capable of offering a supplementary way of feeding a hybrid system with additional power. Its benefits include:

• Reduces fuel consumption
• Reduces CO2
• Supplementary way of feeding a hybrid system with additional power

As the industry rapidly shifts to greater efficiency and reduction in CO2, innovative solutions are becoming increasingly desirable to engine and vehicle manufacturers.

As the global market leader in the design and manufacture of turbochargers for the commercial diesel engine sector, Cummins Turbo Technologies will continue to develop and expand on its innovative solutions to meeting today’s and the future industry challenges
