    Assessment of Gasoline Direct Injection Engine Cold Start Particulate Emission Sources by Oh, Changhoon, Cheng, Wai K.

    Published 2019
    “…This lambda threshold does not correlate with engine speed and load; however, it increases slightly when the intake air is diluted with nitrogen. To assess the fraction of the GDI injected fuel that contributes to the PN, at fixed load and lambda, the injected gasoline is systematically reduced, with premixed methane as balance for the fuel. …”
