In vehicles equipped with knock sensors, it can be difficult to determine the octane number requirement according to the current Coordinating Research Council E-15 procedure which is based on detection of audible knock by trained raters. Therefore, a program was conducted to develop a new procedure which is more suitable for knock sensor equipped vehicles.Due to adaptive actions taken by the electronic knock control system, the acceleration performance of a knock sensor equipped vehicle can be affected by fuel octane number. For the majority of vehicles tested, the acceleration time increased as fuel octane number was decreased. A promising new method was developed to determine vehicle octane number requirement based on acceleration performance.
