Fuel gas injection quantity correction method and device, electronic equipment and storage medium

The invention discloses a fuel gas injection amount correction method and device, electronic equipment and a storage medium, the method can be applied to a natural gas engine system, after the system meets a preset fuel gas injection amount correction enabling condition, a target self-learning MAP of the natural gas engine system is determined, and the target self-learning MAP is used for correcting the fuel gas injection amount. The target self-learning MAP is obtained by carrying out self-learning according to related parameters when the natural gas engine system carries out gas injection amount correction last time; judging whether the target self-learning MAP meets a preset learning requirement or not; if yes, the fuel gas injection amount of the natural gas engine system is corrected according to the current working condition of the natural gas engine system and the target self-learning MAP; otherwise, resetting the target self-learning MAP, and correcting the fuel gas injection quantity of the natural g
