Abstract
This research is part of a collaboration between several Belgian universities investigating the most economical routes for electro- and synthetic energy carriers (fuels). These will be needed to face the climate change issues and ensure the stability of the grid and the security of supply in 2040 and beyond. Important in this are the various energy converters, such as turbines, boilers and internal combustion engines, which will have to move away from their use of fossil fuels. This work looks specifically at whether spark-ignition engines running on green methanol can be used as an alternative to heavy-duty diesel engines in applications that do not lend themselves to electrification. First, an experimental framework was created to discover knock in methanol-fuelled engines. Knock is an undesirable combustion phenomenon that occurs when part of the mixture spontaneously auto-ignites. Since this phenomenon prevents high power and efficiency values, thresholds indicating the limit between a knocking and non-knocking operating point were established. In parallel, a numerical model was developed that allows one to examine how the performance of methanol-fuelled spark-ignition engines will change when moving towards larger displacement volumes. This allows one to compare alternatives one-to-one and find the most sustainable technology-neutral solution for each application.
