<p>PURPOSE:To widen the regenerative range, reduce deterioration of fuel consumption due to actuation of a temp. rising device, and suppress burden on it by retarding fuel injection timing when the exhaust gas temp. exceeds the temp. level which is necessary for re-combustion of organic soluble components. CONSTITUTION:A fuel injection pump 61 is equipped with a timer mechanism 62 with which the fuel injection timing can be changed. A trap 63 collects particulate in the exhaust gas, and when a means 65 judges that it is in the regeneration timing to combust the collected particulate, a means 66 actuates a temp. rising device 64. Therein the exhaust gas temp. is sensed by a sensor 67. A means 68 judges whether the sensed value lies over the level which is necessary for re-combustion of organic soluble components. If judgement is such that the value exceeds the temp. of re-combustion, a means 69 controls the timer mechanism 62 so as to retard fuel injection timing.</p> |
