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

WTW GHG reduction ranges afforded by the different GCI hybrid architectures. 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. Abdul-Manan et al.

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

Green Car Congress

The all-new SEAT Leon offers a range of powertrains that includes multiple electrified variants. 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 company, a member of the Volkswagen Group, has invested more than €1.1

New Golf Variant TGI natural gas model now available to order; three tanks, more CNG range

Green Car Congress

Third natural gas tank for additional range of 80 kilometres ›. The new Golf Variant model now features three natural gas tanks—instead of just two as before—once again increasing the already long range of the CNG drives. liter four-cylinder gasoline engine is even more efficient and responsive than its predecessor.

Researchers at KAUST, Saudi Aramco evaluating low-octane fuels for gasoline compression ignition engines

Green Car Congress

Gasoline compression ignition (GCI) is an experimental engine technology that could consume 25% less energy than a conventional automobile engine. GCI uses a gasoline-type fuel, but rather than ignited with a spark, it is compression-ignited like diesel. Earlier post.)
