[0043] figure 1 This is a flowchart of the defrosting method according to the first embodiment of the present invention; in the first embodiment, the defrosting method includes:
[0044] Step 101: Set the correspondence between the temperature of the engine's cooling water and the first defrost voltage loading time period used by applying the defrost voltage to remove the frost formed between the center electrode and the side electrode of the spark plug; The actual temperature of the cooling water; according to the corresponding relationship between the temperature of the cooling water of the engine and the first defrosting voltage loading time period for removing the frost formed between the center electrode and the side electrode of the spark plug by applying the defrosting voltage, Obtain the first defrost voltage loading time period corresponding to the actual temperature of the engine cooling water; when the engine is stopped, obtain the defrost trigger signal;

[0062] In the first embodiment, in some special cases, applying the defrost voltage to both ends of the center electrode and the side electrode of the spark plug during the first defrost voltage application period cannot completely remove the gap between the center electrode and the side electrode. Frost. Therefore, in the second embodiment, a process of detecting whether the frost formed between the center electrode and the side electrode is removed is added, such as figure 2 Shown. figure 2 It is a flowchart of the defrosting method of the second embodiment of the present invention. See figure 2 , The process includes:
[0063] Step 201: Obtain a defrost trigger signal when the engine is stopped;
[0064] This step is the same as step 101 in the first embodiment.
[0065] Step 202: After the defrost trigger signal is obtained, apply defrost voltage to both ends of the center electrode and side electrode of the spark plug, and detect the center of the spark plug when the defros...

[0070] image 3 It is a flowchart of the defrosting method of the third embodiment of the present invention. See image 3 , The process includes:
[0071] Step 301: Set the air temperature threshold inside the engine; set the second defrost voltage loading time period; and obtain the defrost trigger signal when the engine is stopped;
[0072] In this step, the air temperature threshold inside the engine is used to indicate whether the frost in the engine is exhausted. Generally, when the actual temperature of the air inside the engine is higher than the air temperature threshold, it indicates that the frost in the engine has been removed; otherwise, it indicates that there is still frost in the engine. Further, the air temperature threshold may be 0°C. Of course, it can be understood that the air temperature threshold may also be higher than 0°C, such as 10°C, so as to ensure that the frost in the engine is completely removed.
[0073] Further, the defrost trigger signal can be the...
