摘要： An exhaust emission control system of an internal combustion engine capable of post injection is disclosed which provides control such that the injection timing in sub injection is set to a point earlier than the target injection timing when the sub injection is started, and the injection timing in the sub injection is then delayed to the target injection timing. This realizes the post injection under the optimum conditions and enables an efficient rise in the exhaust temperature while inhibiting deterioration of the drivability due to a rapid change in torque.

摘要： The end of a communication period can be detected reliably and efficiently by a control unit and validity/invalidity of search rules in a search table can be effectively managed. A timer is provided so as to correspond to each entry area of the search table. Then, under control of a timer managing unit, the timer starts a counting operation whenever information is written in a validity management table or a packet in which a communication parameter matches a packet search condition corresponding to information on the validity management table that is set as valid is received. In addition, when a counting time of the timer exceeds a preset time-out time, information indicating the time-out is stored in a time-out management table.
