description The invention discloses an engine health management method and system, and the method comprises the steps: firstly obtaining the exhaust temperature Ti of each cylinder, and then obtaining the average exhaust temperature, the maximum exhaust temperature and the minimum exhaust temperature according to the exhaust temperatures of all cylinders; then Ti-Tave and Tmax-Tmin are set as boundary correction conditions, correction is started when the boundary correction conditions are met, the oil quantity of each cylinder is adjusted, and the oil quantity adjustment quantity of the ith cylinder is M; and when the accumulated oil mass M is larger than the maximum corrected oil mass Mmax or Ti-Tave is not larger than or equal to a preset first temperature threshold value T, correction is completed, and if M is larger than the maximum corrected oil mass Mmax and Ti-Tave is still larger than or equal to the preset first temperature threshold value T, an ith cylinder combustion abnormal signal is sent to an engine for mo
