Machine learning PODA model projects the impact of COVID-19 on US motor gasoline demand

Green Car Congress

The PODA model is a machine-learning-based model to project the US gasoline demand using COVID-19 pandemic data, government policies and demographic information. The Motor Gasoline Demand Estimation Module quantifies motor gasoline demands due to the changes in travel mobility. —Ou et al.

UW Madison team finds methylbutenol a potentially promising biofuel for blending with gasoline

Green Car Congress

A team at the University of Madison-Wisconsin studied critical sooting equivalence ratios and subsequent particulate formation during spark-ignition combustion for blends of ethanol, isobutanol (2-methyl-1-propanol), and methylbutenol (2-methyl-3-buten-2-ol) with gasoline using premixed prevaporized (PMPV) fueling. 2022.124638.

Sugar-derived levulinic esters and cyclic ether show superior anti-knock quality to Euro95 reference gasoline

Green Car Congress

A team from The Netherlands and the US reports that the sugar-derived levulinic esters methyl levulinate (ML) and ethyl levulinate (EL) and the sugar-derived cyclic ether (furfuryl ethyl ether (FEE) demonstrate superior anti-knock quality (in 10% blends) to a reference Euro95 gasoline. —Tian et al.

Aramco, KAUST team finds hybrid gasoline compression-ignition architecture can reduce GHG 26-55% vs. conventional SI

Green Car Congress

At a high level, they found that: Gasoline Compression-Ignition (GCI) hybrids reduce WTW GHG emissions by 7–43% versus unhybridized GCI. Four reference vehicles were equipped with: gasoline spark-ignition (SI) engine. WTW GHG reduction ranges afforded by the different GCI hybrid architectures. Abdul-Manan et al. 2020.114936.

New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

A new study by a team at the National Renewable Energy Laboratory (NREL) concludes that a high-pressure, scalable, intra-city hydrogen pipeline system could improve the economics and logistics of hydrogen delivery, making it potentially cost-competitive with gasoline. kg—approximately equivalent to a gasoline cost of $2.7/gal

SEAT launches all-new Leon; gasoline, diesel, CNG, mild-hybrid, plug-in hybrid; €1.1B investment

Green Car Congress

The new-generation compact car benefits from gasoline (TSI); diesel (TDI); compressed natural gas (TGI); mild-hybrid (eTSI) and plug-in hybrid (eHybrid) units. The new Leon’s offer of standard gasoline engines are all direct-injection, turbocharged units and provide power outputs between 66kW/90PS and 140kW/190PS. Plug-in hybrids.
