Evaluation of non-fuel components on engine knock performance

摘要

The present invention relates to methods and apparatus for the evaluation of non-fuel components within a selected fuel with respect to engine knock performance. A non-fuel component such as a lubricant oil is now evaluated to determine onset of engine knock relative to baseline oil formulations that indicate relative low reactivity and optimum engine performance and those engine oils that exhibit relatively high reactivity and sub-optimum engine performance.
