The invention relates to the technical field of engine control, in particular to a natural gas engine detection method, device and equipment and a storage medium. The method comprises the following steps: monitoring a vibration signal of the natural gas engine in each working period of the natural gas engine; if the target vibration signal is monitored, determining a target phase moment based on the generation time of the target vibration signal and the starting time of the target work period; and determining a target abnormal sound fault type corresponding to the target phase moment based on a first mapping relation between a preset phase moment and an abnormal sound fault type. The method and the device are used for improving the fault detection efficiency of the natural gas engine. 本公开涉及发动机控制技术领域，特别涉及一种天然气发动机检测方法、装置、设备及存储介质。该方法包括：在天然气发动机的每个工作周期中对天然气发动机的振动信号进行监控；若监控到有目标振动信号，则基于目标振动信号的产生时间和目标工作周期的起始时间，确定目标相位时刻；基于预设的相位时刻与异响故障类型之间的第一映射关系，确定目标相位时刻对应的目标异响故障类型。本公开用以提高对天然气发动机进行故障检测的效率。
