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.

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

Researchers from Saudi Aramco and KAUST (King Abdullah University of Science and Technology), with a colleague from Shanghai Jiao Tong University in China, assessed the effects of adopting 4 hybrid architectures on the life-cycle GHG emissions of a novel high-reactivity fuel in an advanced compression-ignition engine (GCI). Abdul-Manan et al.

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.)

KAUST team develops computational model for simulating soot production in gasoline direct injection engines

Green Car Congress

Researchers at KAUST have developed a computational model capable of simulating soot production inside gasoline direct injection (GDI) engines. This new computer model could help car makers improve their engines to cut soot formation. Gasoline contains straight and branched-chain aliphatics, aromatics, alkenes, and cycloalkanes.

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.
