Cummins waste heat expander

Cummins Turbo Technologies is offering a look at its advanced waste heat expander prototype at the Mid-America Trucking Show.

The system, which includes the Holset waste heat expander, can reduce fuel consumption by up to 6 percent, delivering fuel savings of between $4,000 (typical heavy-duty cycle) and $40,000 (typical high-horsepower cycle), depending on the application and engine power.

Adrian Tipling, Cummins Turbo Technologies account executive for Global OEMs, said, “With increasing pressure to reduce CO2 emissions and fuel consumption, engine manufacturers and integrators are searching for fresh ways to achieve improvements in the efficiency of their equipment. Our waste heat expander captures what would otherwise be lost energy – in the form of heat – from a number of sources onboard the vehicle and turns it into useful mechanical or electrical power. The net result is lower levels of environmental pollution and lower bills at the pump.”

The waste heat turbine expander prototype is on display at booth #30035. Cummins Turbo Technologies is part of the Cummins Components Group, which includes Cummins Emission Solutions, Cummins Filtration and Cummins Fuel Systems. The Holset brand has been synonymous with turbocharging for more than 50 years.
