    摘要: An exhaust gas purification filter that is suitable for arrangement in an exhaust passage of an internal combustion engine and for collecting particulate matter contained in exhaust gas, comprises: exhaust gas inflow passages and exhaust gas outflow passages that are arranged alternately; and porous partitions that separate the exhaust gas inflow passages and the exhaust gas outflow passages from each other. Each of the partitions is divided into a coated zone in which a surface of a partition base is coated with a coating layer having a smaller average pore diameter than an average pore diameter of the partition base and a non-coated zone that is located on a downstream side of the coated zone and in which a surface of the partition base is not coated with the coating layer. A pore diameter of the partitions is set such that ash contained in the exhaust gas is able to pass through the partitions in the non-coated zone. A passage resistance of a partition portion located in the coated zone, the passage resistance being in a thickness direction of the partition portion located in the coated zone, is lower than a passage resistance of a partition portion located in the non-coated zone, the passage resistance being in a thickness direction of the partition portion located in the non-coated zone.

    摘要: A liquid additive agent added into an exhaust gas is suppressed from adhering to a sensor. Provision is made for a sensor that is arranged in an exhaust passage of an internal combustion engine; an addition valve that is arranged in the vicinity of or at the downstream side of the sensor in the direction of flow of the exhaust gas, and adds an additive agent into the exhaust passage; a catalyst that is arranged at the downstream side of the addition valve, and receives a supply of the additive agent from the addition valve; and pressure difference generation unit that makes a pressure of the exhaust gas in the surrounding of the sensor higher than a pressure thereof in the surrounding of the addition valve. A pressure difference is caused to generate so that the additive agent is suppressed from flowing toward the direction of the sensor.

    摘要: An exhaust gas purification system is equipped with a burner in an exhaust passage upstream of an exhaust gas purification apparatus and having a burner combustion chamber in which flame is produced. When the temperature of the exhaust gas purification apparatus is raised, the burner produces flame that extends from the interior of the burner combustion chamber to the interior of the exhaust passage when the flow rate of the exhaust gas is not higher than a predetermined flow rate, and the burner causes the size of the flame to be smaller than when it is determined that the flow rate of the exhaust gas is not higher than the predetermined flow rate or to produce flame only in the interior of the burner combustion chamber when it is determined that the flow rate of exhaust gas is higher than the predetermined flow rate.
