Study finds blending gasoline with GTL improves efficiency and lowers emissions in compression-ignition PPC mode

Green Car Congress

In our previous work, we evaluated the performance of two Fischer–Tropsch (FT) GTL diesel fuels with CNs of 52 and 72 in various combustion modes from high (i.e., While future GTL plant owners might take notice of aforementioned insights, producers of high CN GTL diesel must necessarily add low CN compounds in order to decrease the CN. …
