Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

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 Earlier post.). l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4 Exhaust system configuration.

Study Assesses Product Attribute Trade-offs and Technological Progress; Meeting Proposed Obama Fuel Economy Standards Will Require Downsizing and Change in Fleet Mix

Green Car Congress

Changes in the attributes (clockwise from upper left, weight, power, fuel economy and torque) of the Honda Accord over time as an example of fleet trends in the US. In contrast, fuel economy actually increased by 15% during that period. Volvo is the most efficient manufacturer of light duty trucks, followed by Subaru, GM and Honda.

Pinnacle 4-stroke opposed-piston SI engine shows fuel economy improvements of between 30-60% at light loads, 12-30% at medium loads over conventional

Green Car Congress

The results represent a light-load indicated efficiency improvement of 15-30% (up to 40.9%). With the extended lean operation of the sleeve-valve engine, NO x emissions remain low for light to medium loads and rise back to typical levels during the brief enrichment periods required to maintain competitive BMEP levels at higher loads.
