Fuel oil information processing method, engine management device, medium and controller

The invention belongs to the technical field of engine fuel oil control, and particularly relates to a fuel oil information processing method, an engine management device, a medium and a controller. According to the method, the working condition of the engine is subjected to partition calibration, the preset reference physical quantity threshold condition is combined, the fuel quality information is processed under the preset working condition by utilizing the detection and response information of the control unit on the detonation phenomenon of the inferior oil product, and then the judgment of the fuel information is improved by combining the collection and processing of the fuel filling information; the operation state of the engine is further improved by combining the working condition information with the adjustment of the ignition angle; according to the method and the product, on-board diagnosis (OBD) capacity can be met, meanwhile, the adaptability of the engine to oil products is improved, the high f
