Abstract [en]

This report is a theoretical study of the potential an ICE (internal combustion engine) has when combined with the load case of a high-performance series hybrid drivetrain. It breaks down the different theoretical variables that affect engine efficiency and possible limitations that arise. The report then moves on to specifying the current emerging technologies associated with increasing engine efficiency such as active, and passive prechamber ignition. The different technologies strengths and weaknesses were then compared with each other to decide the best strategies and technologies to move forward with. Here efficiency gain potential was compared to price, performance and complexity. The different technologies were compared in two separate steps firstly the technologies were compared individually, then the best systems were compared to different engine configurations in an iterative process. Here the most balanced solution was found using a passive prechamber to allow higher compression ratio while allowing better timing control. This was later combined with a Miller cycle strategy resulting in a theoretical efficiency improvement of ~8%. This would potentially allow a high performance vehicle to match a midrange diesel engine in fuel economy.
