Claim Text:
1. A method for detecting addition of engine lubricant for an aircraft engine, comprising: determining, using an adding detection module, whether the difference value between the lubricant quantity at a first timing and that at a second timing is greater than a first threshold value; delaying a period and determining, using a verification module, whether the difference value between the lubricant quantity at a third timing and that at a fourth timing is greater than a second threshold value in response to that the difference value between the lubricant quantity at the first timing and that at the second timing is greater than the first threshold value; and detecting, using an increment calculation module, the lubricant increment in response to that the difference value between the lubricant quantity at the third timing and that at the fourth timing is greater than the second threshold value, wherein the detecting the lubricant increment comprises obtaining a maximum lubricant value, delaying a period and re-obtaining a lubricant increment value, re-obtaining lubricant increment values for multiple times at intervals equivalent to a duration of the period; and calculating an average increment value of the lubricant increments.
