AN OIL LIFE MONITORING SYSTEM AND A METHOD TO MONITOR OIL LIFE OF AN ENGINE

摘要

TITLE : "AN OIL LIFE MONITORING SYSTEM AND A METHOD TO MONITOR OIL LIFE OF AN ENGINE" This invention relates to an oil life monitoring system for a diesel engine system (10), characterized by comprising a viscosity loss module (104) that determines a percentage of viscosity loss (VL%) of engine oil based on a post-combustion injection quantity and a post-combustion injection time, a viscosity gain module that determines a percentage of viscosity gain VG% of engine oil based on at least one of fuel evaporation and soot accumulation in said engine oil; and a remaining oil life module (108) that communicates with said viscosity loss module (104) and said viscosity gain module (106) and that determines a percentage of oil life remaining (PLOR) based on at least one of said percentage of viscosity loss (VL%) and said percentage of viscosity gain (VG%). {FIGURE - 1}
