    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： An exhaust cleaning filter for collecting particulate matter contained in exhaust gas and suitable for being disposed in an exhaust passage of an internal combustion engine is provided with: an exhaust gas inflow passage and an exhaust gas outflow passage disposed in alternating fashion; and a porous partition wall for setting the exhaust gas inflow passage and the exhaust gas outflow passage at a distance from each other. A small pore region is sectioned off on the upstream side of the partition wall and a large pore region is sectioned off on the downstream side of the partition wall. The average pore diameter of the partition wall in the large pore region is set to be greater than the average pore diameter of the partition wall in the small pore region, and is set so that ash contained in the exhaust gas is able to pass through the partition wall. The exhaust purification filter is provided with a promoting member for promoting the passing of exhaust gas that has flowed into the exhaust gas inflow passage, through the partition wall in the small pore region, and promoting inflow into the exhaust gas outflow passage.

    摘要： In the case where a low-pressure-side supercharging pressure acquired value corresponding to the pressure of inlet gas at the outlet of a low-pressure compressor operated in a twin supercharging mode is less than a target supercharging pressure in a single supercharging mode, changeover from the twin supercharging mode to the single supercharging mode is prohibited. Meanwhile, in the case where the low-pressure-side supercharging pressure acquired value is equal to or greater than the target supercharging pressure, the changeover from the twin supercharging mode to the single supercharging mode is permitted. Alternatively, in the case where a supercharging pressure during operation in the single supercharging mode is less than a target value of the pressure of supply gas at the outlet of the low-pressure compressor in the twin supercharging mode, changeover from the single supercharging mode to the twin supercharging mode is prohibited. Meanwhile, in the case where the supercharging pressure is equal to or greater than the target value, the changeover from the single supercharging mode to the twin supercharging mode is permitted.

    摘要翻译： 在以双增压模式操作的低压压缩机出口处的入口气体压力相应的低压侧增压压力获取值小于单增压模式中的目标增压压力的情况下， 从双增压模式到单增压模式是禁止的。 同时，在低压侧增压压力获取值等于或大于目标增压压力的情况下，允许从双增压模式向单次增压模式的切换。 或者，在单增压模式下的运转时的增压压力小于双增压模式的低压压缩机出口处的供气压力的目标值的情况下，从单增压模式切换到 双增压模式是禁止的。 同时，在增压压力等于或大于目标值的情况下，允许从单增压模式向双增压模式的切换。
