EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

in August and September 2015—the highest share in more than a decade, according to data from the US Energy Information Administration (EIA). One significant trend is engine downsizing coupled with turbocharging. Turbochargers work by using a turbine driven off the exhaust gas to pressurize the intake air.

Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust. The rapid market penetration of GDI vehicles has led governments to impose stricter standards to control PM emissions.
