PNNL team develops onboard fuel separation technology to enable octane-on-demand for improved fuel economy

Green Car Congress

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. This problem is common to both gasoline and diesel engines.
