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.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9

IEA: improving efficiency of road-freight transport critical to reduce oil-demand growth; three areas of focus

Green Car Congress

Although trucks are a major contributor to the growth in transport-fuel consumption and emissions, the sector receives far less attention and policy focus than passenger vehicles, the IEA noted. Only four countries have energy-efficiency standards for heavy trucks, compared with some 40 countries with passenger-vehicle standards.
