At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Cost of the new engine relative to gasoline baseline. Earlier post.). l/100 km) for a vehicle of that size.

UPS announced an update to 125 Workhorse E-GEN series hybrid electric delivery trucks that improve fuel economy as part of the company’s broader Rolling Laboratory approach. A compact, quiet-running 650cc 2-cylinder engine replaces the previous 2.4L The smaller engine will improve fuel economy, however.

Southwest Research Institute (SwRI) has built a demonstrator vehicle, based on a 2012 Buick Regal GS, incorporating the latest D-EGR (dedicated EGR) technology ( earlier post ), an outgrowth of SwRI’s HEDGE (High Efficiency Dilute Gasoline Engine) consortium projects ( earlier post ). The compression ratio of the engine was increased to 11.7:1

Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. Because exhaust-driven reforming uses only waste engine heat, it avoids this efficiency hit, the authors note. —Sall et al.
