Evolving technology and a reoccurring energy crisis creates a continued investigation into the search for sustainable and clean-burning renewable fuels. One possibility is hydrogen that has many desirable qualities such as a low flammability limit promoting ultra-lean combustion, high laminar flame speed for increased thermal efficiency and low emissions. However, past research discovered certain limiting factors in its use such as pre-ignition in spark ignition engines and inability to work as a singular fuel in compression ignition engines. To offset these issues, this work documents manifold injection of a hydrogen/carbon monoxide mixture in a dual-fuel methodology with biodiesel. While carbon monoxide does degrade some of the desirable properties of hydrogen, it acts partially like a diluent to restrict pre-ignition. The result of this mixture addition allows the engine to maintain power while reducing biodiesel fuel consumption with a minimal NOx emissions increase.
► Reformate increased the flammability limits, reduced emissions, and increased fuel economy.
► Reformate maintained the power output while improving fuel economy of biodiesel.
► Reformate decreased fuel conversion and combustion efficiency but increased thermal efficiency.
► CO acted as a combustion enhancer and diluent.
► Reformate increased NOx as a function of increasing reformate mixture levels.
