摘要： An exhaust gas purifying system for an automotive internal combustion engine (1). The exhaust gas purifying system comprises a particulate filter (13) dsposed in an exhaust gas passageway (12) of the engine to collect particulate in exhaust gas flowing through the exhaust gas passageway (12). The collected particulate is burnt off to be removed by raising a temperature of exhaust gas in a coridition in connection with the particulate filter (13). A plurality of devices (3,8,11,51) are provided for raising the temperature of exhaust gas to be introduced into the particulate filter (13) through the exhaust gas passageway (12) when the collected particulate is burned off to be removed. Additonally, a control unit (15) is configured to select at least one of the devices (3,8,11,51) in accordance with an engine operating region and preferentially operate the selected at least one of the devices (3,8,11,51) for raising the exhaust gas temperature.

摘要： A particulate matter deposit amount accumulated in a diesel participate filter (4) is calculated as a first particulate matter deposit amount from a pressure loss of the filter (4) (S33). The particulate matter deposit amount accumulated in the filter (4) is calculated as a second particulate matter deposit amount from another parameter (S34). It is determined whether or not there is front end blockage of the filter (4) based on a comparison between the first particulate matter deposit amount and second particulate matter deposit amount (S36, S43). When there is a front end blockage of the filter (4), the regeneration device is controlled to perform regeneration of the filter (4) for a longer period than the normal regeneration period of the filter (4) (S22).

摘要： A filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20) for a vehicle is regenerated by fuel injection control. A controller (16) calculates a representative value of the operating condition of the diesel engine (20) during a latest predetermined time period, and determines the traveling condition of the vehicle on the basis of this representative value. When the representative value corresponds to a highway traveling condition, fuel injection control is performed in accordance with a pattern for burning all of the particulate matter trapped in the filter (10). Under any other conditions, fuel injection control is performed in accordance with another pattern. Hence optimum filter regeneration can be performed depending on the traveling condition of the vehicle.

摘要： A regeneration control device which regenerates a filter (4) which traps particulate matter in the exhaust gas of an engine (1) is disclosed. The regeneration control device includes a first temperature sensor (16, 17), which detects one of an upstream temperature and a downstream temperature upstream and downstream of the filter (4) as a first temperature (Tin, Tout); a second temperature sensor (16, 17), which detects the other temperature as a second temperature (Tin, Tout); and a microcomputer. The microcomputer programmed to compute an estimated value (Tbede2) for the second temperature based on the first temperature detected by the first temperature sensor (16, 17), compute an estimated bed temperature (Tbed2) of the filter based on the second temperature detected by a second temperature sensor (16, 17) and the estimated value (Tbede2) for the second temperature, and perform engine control for increasing the temperature of the exhaust gas based on the estimated bed temperature (Tbed2).

摘要： To regenerate a diesel particulate filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20), a controller (16) raises the temperature of the exhaust gas through fuel injection control of a fuel injector (23), and thus burns the particulate matter trapped in the filter (10). The controller (16) controls the fuel injector (23) to raise the temperature of the exhaust gas to a higher temperature as the amount of particulate matter trapped in the filter (10) decreases, thereby realizing effective regeneration while preventing the temperature of the filter (10) from becoming excessively high.
