The air engine assembly includes a liquid reservoir, a pressure valve, a high-pressure air tank, at least one throttling control mechanism, and an air engine. The liquid reservoir is connected to the inlet of the high-pressure air tank via the pressure valve. The outlet of the high-pressure air tank is connected to the input of the throttling control mechanism, and the output of the throttling control mechanism is connected to the air engine. This invention's air engine assembly with throttling control function enables precise adjustment of the intake air volume and engine output. Furthermore, due to the inclusion of the liquid reservoir, the single-trip driving distance of the air-powered vehicle is longer, meeting usage requirements.

The acquisition method of the second semantic information is the same as that of the first semantic information, and will not be described in detail.

[0158] The leak detection module is used to determine if a leak exists at the location of the gas storage device recorded in the corresponding leak detection record if at least one key leak semantic appears in the target semantic of the second semantic information. The target semantic is a single semantic term corresponding to the second semantic information; the key leak semantic is, for example, "pressure difference greater than xx Pascals." The location of the gas storage device is, for example, "which cylinder number."

[0159] The working principle and beneficial effects of the above technical solution are as follows:

[0160] This application splits the acquired leak detection records to obtain leak detection record items; based on the first semantic information corresponding to the record type of the record item, it calculates the priority traversal value of the leak detection record item for different record types, improving the accuracy of the priority traversal value; it traverses the leak detection record items in descending order of priority traversal value, improving the efficiency of leak detection; it obtains the second semantic information of the leak detection record item, and if at least one leak key semantic appears in the second semantic information, it determines that there is a leak at the location of the gas storage device corresponding to the leak detection record item, improving the rationality of the leak determination and further improving the safety of the air engine operation.

[0165] Step 4: Based on the power difference between the required output power and the current output power, determine the need for flexible electronic control. If the determination result indicates that flexible electronic control is required, then perform the corresponding flexible electronic control.
