Multi-cylinder engine fuel cut-off method and device, motorcycle and storage medium

The invention provides a multi-cylinder engine fuel oil cut-off method and device, a motorcycle and a storage medium. According to the method, N air cylinders of the multi-cylinder engine are ranked to determine O air cylinders ranked in a preset range, and for at least one air cylinder with the misfire rate larger than a preset value in the O air cylinders, a controller matched with the air cylinder is used for conducting fuel oil cut-off on the at least one air cylinder. That is, the air cylinder with the high misfire rate can be determined by sequencing the N air cylinders according to the misfire rates of the N air cylinders, and the controller matched with the air cylinder with the high misfire rate can be determined for the air cylinder with the high misfire rate. Therefore, the controller matched with the air cylinder with the high misfire rate can be used for cutting off fuel oil of the air cylinder with the high misfire rate, unburned gas in the air cylinder with the high misfire rate cannot enter a
