Three sunflower oil/diesel blends and pure sunflower oil were tested in a CI engine using the manufacturer’s settings, two altered injection timings (IT±2oCA) and injector protrusions (IP±0.5mm). 36 Fuel­IT­IP configurations were completed, plus the reference run with diesel. A life cycle analysis (LCA) was conducted and fossil CO2 was counted. The configurations were compared using analytical hierarchy process (AHP) that was applied for three cases: 1. focusing on engine performance, 2. environmentally driven and 3....
