Test calibration evaluation method for influence of low-grade fuel oil on engine knock

The invention discloses a test calibration evaluation method for the influence of low-grade fuel oil on engine knock, and belongs to the technical field of automobile tests.The test calibration evaluation method comprises the steps that test condition data and environmental condition data are obtained, and preset test conditions and environments are selected one by one in sequence according to the test condition data and the environmental condition data; acquiring a plurality of steady-state working condition data of the finished engine of the gasoline with the mark number Y, and according to the plurality of steady-state working condition data of the finished engine of the gasoline with the mark number Y, obtaining an arithmetic mean value of knocking thrust angle data of the gasoline with the mark number Y in each working condition point collection duration, and judging whether the requirement is met or not according to the arithmetic mean value of the knock thrust angle data in the collection duration of e
