Summary:

The combustion of hydrogen (H2) as a fuel is attractive due to its zero-carbon nature and combustion-enhancing properties when used to supplement other fuels. However, the challenge of using H2 as a fuel for transportation applications is the difficulty of onboard storage. One solution to this is to crack onboard stored ammonia (NH3) into H2 which can be supplied to the combustion chamber. However, the reforming process is not always 100 % efficient which can lead to the presence of NH3 in the combustion process. The presence of NH3 can influence engine performance, combustion and emissions. Therefore, this experimental study reports the differences in engine performance between H2 and NH3 reformate mixtures (H2/NH3/N2) added to gasoline in a dual-fuel engine setup under both stoichiometric (λ=1.0) and lean-burn (λ>1.0) operating conditions in a spark ignition (SI) engine. In this study, gasoline was used as the main fuel, with the H2 and NH3 reformate blends studied having energy substitution ratios ranging from 0% to 23%. The results showed that the use of H2 and NH3/H2/N2 mixtures reduced carbon-based emissions. However, there was an increase in nitrogen-based emissions compared to gasoline with increased H2 and NH3 content
