<p>Disclosed is a method of collecting and monitoring an oil path pressure signal, wherein a central processing unit uses a path pressure sensor to measure an oil injection path pressure signal at the point of oil injection and a peak path pressure signal within a pre-set time interval T, and controls the amount of oil injected according to the oil injection path pressure signal; the central processing unit also determines whether or not the peak path pressure signal exceeds a pre-set range, and monitors the dynamic drift of the peak path pressure signal in the start-up phase; when the peak path pressure signal exceeds the pre-set range or the dynamic drift of the peak path pressure signal exceeds the pre-set value, the central processing unit substitutes the actual path pressure signal with a pre-set path pressure value, thereby entering a limp home mode. The method can better serve an engine, making engine operation even more highly efficient.</p> |
