Verification method for super knocking difference of engine

The invention discloses a verification method for super knocking difference of an engine. The method comprises the following steps of selecting a test working condition with super knocking frequency meeting requirements; preprocessing a test sample machine; respectively carrying out cyclic test by utilizing reference samples and test samples and respectively acquiring at least five groups of effective data, wherein the cycle test comprises a carbon deposit removal cycle, a super knocking run-ahead cycle and a super knocking test cycle; and evaluating the super knocking inhibition difference between the reference samples and the test samples according to the obtained effective data. According to the invention, the inhibition effect of a special engine oil and fuel additive for inhibiting super knocking on super knocking can be accurately evaluated. 本发明公开了一种发动机超级爆震差异性验证方法，其中，包括如下步骤：选取超级爆震频次符合要求的试验工况；对试验样机进行预处理；分别利用参比样品、测试样品进行循环测试并分别获取至少五组有效数据；其中，循环测试包括清除积碳循环、超级爆震预跑循环和超级爆震测试循环；根据所获取的有效数据评价参比样品和测试样品的超级爆震抑制性差异。本发明
