WEBINAR TITLE AND DESCRIPTION

03/25/2021

How can co-optimized fuels and spark-ignition (SI) engines enhance efficiency while reducing carbon emissions of light-duty (LD) passenger vehicles?

SI engines using gasoline are projected to remain a significant percentage of the LD vehicle fleet for decades. The Co-Optima initiative has demonstrated that it is possible to improve the efficiency and reduce the environmental impact of SI engines with higher amounts of biofuel blend components chosen to improve key fuel properties. This webinar describes Co-Optima’s approach to the development of selection criteria and identification of these blendstocks, as well as analysis of their potential impacts on the sustainability of LD SI fuels and engines.

Daniel Gaspar, Pacific Northwest National Laboratory (PNNL)

How can fuels and combustion reduce pollutants from future diesel engines?

Mixing-controlled compression-ignition engines—such as diesel engines—have many desirable attributes, including high fuel-conversion efficiencies. Nevertheless, these engines produce emissions of soot and nitrogen oxides (NOx) that must be mitigated by emissions control technology. This webinar discusses identification of bioblendstocks with low-net-carbon emissions and desirable fuel properties and approaches for curtailing soot, NOx, and net-carbon emissions by combining these sustainable fuels with a new combustion technology called ducted fuel injection.

What environmental and economic benefits might be realized by co-optimizing fuels and SI engines for LD passenger vehicles?

Advances in engine design coupled with performance-enhancing biofuel blends could lower LD vehicle ownership costs while offering environmental benefits. This webinar discusses Co-Optima findings that characterize the cost and environmental effects of performance-enhancing bioblendstocks, their potential benefits for fuel producers, their potential for production at commercial scale, and associated societal benefits.

What environmental and economic benefits might be realized by co-optimizing fuels and engines for medium-duty (MD) and heavy-duty (HD) commercial vehicles?

Co-optimizing fuels and engines has the potential to enhance the economics and reduce the environmental impact of the MD and HD transportation sectors. This session discusses Co-Optima’s characterization of the cost and environmental effects of performance-enhancing bioblendstocks, their potential benefits for fuel producers, integrated modeling exploring their potential for production at commercial scale, and associated societal benefits.

What unconventional engine-fuel combinations show the greatest promise for efficiency improvements beyond current LD/MD/HD technologies?

Multiple unconventional combustion concepts offer substantial improvements in engine thermal efficiency. This webinar examines how changes to the composition and properties of future fuels could enable approaches such as multimode operation of LD SI gasoline engines and advanced compression ignition operation of MD and HD engines.
