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.

In-use emissions report for Achates heavy-duty OP diesel shows substantial margin to most stringent EPA NOx proposed regulation

Green Car Congress

Achates Power has released initial in-use NO x measurements from the cleaner, heavy-duty diesel engine it developed in a project funded by the California Air Resources Board (CARB) and several partners. Both CARB and EPA have introduced Low Load requirements, in-use NO x measurement updates, and limits on permissible real-world emissions.

EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

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.
