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).

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.)
