Abstract

Due to global warming, industries are focusing on reducing CO2 emissions by exploring e-fuel. E-fuel, produced via Fischer-Tropsch synthesis using H2 from renewable energy and CO2 from the atmosphere, resembles diesel and can power existing diesel engines. Its composition can be easily adjusted during production to enhance combustions. To optimize combustion performance, an experiment was conducted using a 0.5-liter, single-cylinder Diesel engine with an externally driven supercharger. The study involved three types of e-fuel at low, medium, and high loads under steady state conditions: engine speed 2000 rpm, injection pressure 140 MPa, and EGR 0%. Various properties of e-fuel such as density, distillation, cetane number, kinematic viscosity, and reaction rate were analyzed for their impact on ignitability, heat balance, and emissions (NOx and soot). The goal was to identify conditions that optimize combustion efficiency.
