Abstract

Undertaking a thorough investigation for decarbonizing transportation of the most recent technical advancements in the field of renewable fuel in spark ignition engines is the main goal of this cutting-edge research. In this research, a simulative investigation including model validation of the genset engine using a spark ignited powered by methanol port fuel injection was carried out. The GT-suite model was validated with a V-type 8-cylinder turbocharged and intercooler engine. Then the model was further used for the analysis of potential methanol fuel reforming by the heat recovery from exhaust energy that has recently emerged as a key research and supported by several industries due to their advantageous properties. A post-oxidation phenomenon mechanism was adopted to vary the exhaust pressure and temperature by tuning fuel injection and spark timing that can provide favorable conditions for the methanol-reforming. It should be noted that the optimal retarding of spark timing can benefit better heat recuperation for methanol to hydrogen reforming as it requires a temperature between 200-300℃ to start the reaction. However, the key barrier of this technology is the suitable catalyst, optimal chemical reactivities, and combustion process environment need to be achieved. Specifically, in the future, the use of several alternative fuels will be closely examined as part of this comprehensive study that seeks to explore the complex dynamics of fuel reforming, engine efficiency, emissions cut, and overall performance that may fulfill the respective countries' decarbonization goals.
