Short summary
By combining approaches involving chassis dynamometer measurements and environmental chamber simulations, we find that gasoline direct injection (GDI) vehicles contribute more primary aerosol and secondary organic aerosol than port fuel injection (PFI) vehicles. Our results highlight the considerable potential contribution of GDI vehicles to urban air pollution, since the market share of GDI vehicles will dominate over that of PFI vehicles in the future.
