Researchers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed an onboard separation system that could support increased fuel economy and lower greenhouse gas emissions as part of an octane-on-demand fuel-delivery system. Unfortunately, these engines exacerbate engine knock.

Improving fuel economy exhibits diminishing returns in fuel savings, according to a brief analysis by the US Energy Information Administration (EIA). Similarly, the fuel and cost savings of improving fuel economy from 12 mpg to 15 mpg are the same as increasing from 30 mpg to 60 mpg.

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. In the analysis, EPA uses overall fuel economy in mpg equivalent (mpge) and tailpipe CO 2 emission values.
