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.

EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share

Green Car Congress

Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed. Fuel economy. Source: EPA. mpg, which is 0.5

Roland Berger study outlines integrated vehicle and fuels roadmap for further abating transport GHG emissions 2030+ at lowest societal cost

Green Car Congress

Optimized internal combustion engines are the major contributor to the reduction of passenger car GHG emissions with significant improvements until 2020 and the subsequent penetration of more effective alternative technologies into the fleet. For the reference case, the model assumed extension of the existing legislation to 2030.
