Abstract

<div>Knock has historically been one of the main limitations on spark ignition (SI) engine compression ratio and hence efficiency. The trend to downsizing or rightsizing in recent years, driven by ever-reducing carbon dioxide (CO<sub>2)</sub> targets, has increased the relevance of the knock limit f...
