Their study was published online 21 December in the ACS journal Energy & Fuels. When used in diesel engines, biodiesel usually exhibits several combustion-related advantages, including reductions in CO, UHC and PM emissions, as well as a net CO 2 reduction. However, with an energy density 13% lower than diesel (37.5
