Alternative RON estimation method by using pressure oscillation analysis, serving novel spark ignition fuel development
For almost a century, the knock-resisting ability of a spark ignition fuel has been quantified with the RON and MON indications, conforming to the corresponding ASTM-D2699 and D2700 methods, respectively. These testing methods rely on specific pressure pickup technology that acts like a low-pass signal filter, thereby cutting off high frequency cylinder pressure information. Within a second-genera
