The embodiment of the invention discloses a method for researching the sensitivity of an engine and a related device, which are used for reducing the test period of the engine. The method provided by the embodiment of the invention comprises the steps of obtaining to-be-studied parameters; determining test parameters according to the research range of the to-be-researched parameters; establishing a virtual rack; the parameters for testing are input into the virtual rack; operating the virtual rack to perform single-factor sensitivity analysis on the test parameters to obtain a single-factor performance simulation result; performing sensitivity sorting on the to-be-studied parameters according to single-factor performance simulation results until all the to-be-studied parameters obtain the single-factor simulation results; recognizing more than two sensitive variables according to the sensitive sequence; performing full-factor performance sensitivity research on the sensitive variables to obtain full-factor pe
