The transition to CO2-neutral propulsion in the maritime sector involves the phasing out of fossil fuels. Methanol is a suitable “green fuel” candidate, but its hampered autoignition properties place new demands on Compression Ignition (CI) engin

In previous research, there have been more investigations on methanol blended with other fuels such as diesel, biodiesel, gasoline, etc., but fewer investigations on methanol with ignition additives as a mono-fuel. To better understand the methanol m

We present the results of a numerical model which has been developed for estimating the contribution to the methane slip from different sources in a four-stroke dual-fuel marine engine running on natural gas. The model is a thermodynamic three-zone z

In this study ignition of premixed ammonia was tested using a compression-ignited (CI) pilot fuel. n-heptane (C7H16) was used as pilot fuel, injected with a GDI injector, enabling very small pilot fuel injections. With this setup, the engine was run
