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. —Han et al.

DOE proposes revising procedures for calculating petroleum-equivalent fuel economy of EVs for use in CAFE calculations

Green Car Congress

The change, petitioned for by the Natural Resources Defense Council and Sierra Club in 2021, would decrease the EV fuel economy values used in calculating CAFE compliance, thereby forcing automakers to either sell more EVs or to improve their other models to remain in regulatory compliance. DOE published a final rule on 12 June 2000.

New cars in Europe in 2013 collectively met 2015 CO2 target two years ahead of the deadline

Green Car Congress

AFV are alternative fuel vehicles: electric, LPG, NG-biomethane, E85, biodiesel, hybrid and plug-in vehicles. The average per-km CO 2 emissions for gasoline-fueled cars was 128.62 grams; and for alternative fuel vehicles (electric, LPG, NG-biomethane, E85, biodiesel, hybrid and plug-in vehicles), 104.14

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. With that as a premise, they go on to show that the efficiency of existing vehicles can be both positively and negatively affected by ethanol content, ranging from ?15% 15% to +24%.

UK auto industry warns anti-diesel agenda and slow uptake of EVs could mean missing 2021 CO2 targets; rising CO2 average in 2017

Green Car Congress

The UK automotive industry warned that the current anti-diesel agenda combined with the ongoing slow take-up of electric vehicles could mean industry misses its next round of CO 2 targets in 2021, with negative consequences for the UK’s own climate change goals. For pure battery-powered vehicles, take-up is even lower (0.5%).
