Method and device for testing set compression ratio upper limit of mass production engine and medium

The invention relates to a method and device for testing the set compression ratio upper limit of mass production engines and a medium. The method comprises the steps of S1, selecting an engine compression ratio; s2, formulating a super knock occurrence test working condition; s3, measuring the compression ratio of the engine, and selecting the measured engine; s4, loading the tested engine; s5, testing the rotating hub of the whole vehicle to obtain super knock data; s6, determining the upper limit of the compression ratio. According to the invention, the working efficiency is greatly improved, the compression ratio of the engine can be tested on a large scale, the compression ratio of the tested engine is ensured to have a smaller interval, and the increase of production cost caused by an excessively harsh compression ratio limit value is effectively avoided. 本发明涉及一种量产发动机设定压缩比上限的测试方法、装置及介质；方法包括S1选取发动机压缩比；S2制定超级爆震发生试验工况；S3测量发动机压缩比，选取被测发动机；S4被测发动机装车；S5整车转毂测试，获取超级爆震数据；S6确定压缩比上限。本发明极大提高了工作效率，可以实现大批量测试发动机压缩比，保证被
