摘要： PROBLEM TO BE SOLVED: To provide an introduction pipe connecting structure which allows removal by separating particle matter or the like once adhered and deposited onto the inlet part of the introduction pipe so that the inlet of an exhaust gas introduction pipe is prevented from being blocked by a particulate matter or the like in a junction of an exhaust gas pipe line through which exhaust gas flows and an exhaust gas introduction pipe in a continuity with detection equipment, and exhaust emission purification system.
SOLUTION: In a junction of an exhaust gas pipe line 11 through which exhaust gas flows and an exhaust gas introduction pipe 31a communicating with detection equipment 31, the introduction pipe 31a is provided so as to be projected in the exhaust gas pipe line 11. In addition, deposit-separation members 50, 50A, 60 are provided to the projection 31aa of the exhaust gas introduction pipe 31a.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission purification method and exhaust emission purification system for determining the forced regeneration starting timing of a DPF on the basis of differential pressure across the DPF, which can scavenge the exhaust passage side of an introduction pipe in a differential pressure sensor and prevent a blockage of the exhaust passage side by blowing off PM and soot deposited thereon.
SOLUTION: When closing an exhaust throttle valve arranged on the upstream side of an exhaust emission purification device at deceleration, braking or the like of a vehicle, a communication destination on the exhaust passage side of a first introduction pipe for propagating pressure on the upstream side of the exhaust emission purification device to a differential pressure sensor is changed from the differential pressure sensor side to a backwash passage side communicating with the upstream side of the exhaust throttle valve by passage change operation of a passage switching means. Thereby, the exhaust gas in which pressure on the upstream side of the exhaust throttle valve rises is introduced in the exhaust passage side of the first introduction pipe to be scavenged.

摘要翻译：要解决的问题：提供一种排气净化方法和排气净化系统，用于基于DPF上的差压来确定DPF的强制再生开始时间，该DPF可以清除导入件的排气通道侧管道在差压传感器中，并通过吹掉沉积在其上的PM和烟炱来防止排气通道侧的堵塞。解决方案：当在排气净化装置的上游侧配置有排气净化装置的减速，制动等关闭排气节流阀时，将用于传播压力的第一导入管的排气通路侧的通信目的地排气净化装置的上游侧通过通过切换装置的通过变更动作，从差压传感器侧向与排气节流阀的上游侧连通的反洗通路侧进行变化。由此，排气节流阀上游侧的压力上升的排气被引入第一导入管的排气通路侧，以被清扫。版权所有（C）2008，JPO＆INPIT
