UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

The gasoline direct injection (GDI) engine is one of the most prominent technologies car manufacturers adopted to achieve the fuel economy and carbon dioxide emission goals established in 2012 by the US Environmental Protection Agency. A strong absorber of solar radiation, black carbon exhibits significant climate warming properties.
