[0105] Based on the first embodiment of the above-mentioned engine fuel cut control device of the present invention, a second embodiment of the engine fuel cut control device of the present invention is proposed.

[0106] In this embodiment, the data acquisition module 10 is further configured to acquire the maximum carbon load of the gasoline engine particulate filter at a preset temperature; according to the maximum carbon load Safe carbon load at the set temperature.

[0107] Further, the data acquisition module 10 is also used to acquire the preset temperature and the reference carbon load of the gasoline engine particle trap before the engine is cut off; and the gasoline engine particulate trap is at a preset position after the engine is cut off. The actual temperature; the maximum carbon loading of the gasoline engine particulate filter at the preset temperature is determined according to the actual temperature and the reference carbon loading.

Abstract

The invention belongs to the technical field of automobiles, and discloses an engine fuel cut-off control method, device and equipment and a storage medium. The safe carbon loading capacity of the gasoline engine particle trap at the preset temperature is obtained, then the current center temperature and the current carbon loading capacity of the gasoline engine particle trap are obtained, and then fuel cut-off control is conducted on the engine according to the safe carbon loading capacity, the current center temperature and the current carbon loading capacity. According to the method, the safe carbon loading capacity of the gasoline engine particle trap at the preset temperature is obtained, fuel cut-off control is conducted on the engine according to the safe carbon loading capacity, the current center temperature and the current carbon loading capacity, and whether the current center temperature and the current carbon loading capacity at the current moment meet the fuel cut-off condition of the engine or not can be judged according to the safe carbon loading capacity; therefore, whether fuel cut-off of the engine occurs or not can be accurately controlled, the gasoline engine particle trap is effectively protected, and the gasoline engine particle trap is prevented from being burnt out during passive regeneration.

Description

technical field [0001] The invention relates to the technical field of automobiles, and in particular, to a method, device, equipment and storage medium for controlling oil cut off of an engine. Background technique [0002] Gasoline Particle Filter, the full English name is Gasoline Particle Filter, hereinafter referred to as GPF. GPF is used for exhaust aftertreatment to capture solid soot particles in engine exhaust. During the passive regeneration of GPF, a large amount of heat will be released due to the combustion of soot, which will cause the temperature of the GPF carrier to rise rapidly. Therefore, how to accurately control whether the engine oil is cut off to effectively protect the gasoline engine particulate filter has become an urgent problem to be solved. [0003] The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is the prior art.
