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. Unfortunately, these engines exacerbate engine knock.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Studies highlight effects of different gasoline components on fuel economy, combustion and emissions

Green Car Congress

Researchers at Jilin University (China) have investigated the effect of gasoline components on fuel economy, combustion and emissions in a GDI (gasoline-direct-injection) engine. The team subsequently followed up this first study with a second, exploring the effects in a PFI (port-fuel-injection) engine.

DOE: Life cycle GHG emissions for 2020 electric small SUV were half those of a conventional gasoline small SUV

Green Car Congress

Using current technologies, all evaluated biofuel, battery electric, and hydrogen fuel cell vehicle pathways offer significant C2G GHG emissions reduction compared to the current gasoline internal combustion engine vehicle. C2G emissions are a sum of WTW emissions and emissions associated with vehicle manufacturing.

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 Cost of the new engine relative to gasoline baseline. Earlier post.). l/100 km) for a vehicle of that size.
