Patent number: 11891939Abstract: An under-floor catalyst (33) includes a GPF (41) capable of trapping fine exhaust particles in exhaust gas, and a downstream-side catalyst (42) positioned on the downstream side of GPF (41). GPF (41) can be supplied with secondary air. When an internal combustion engine (10) is stopped during travel, the secondary air is supplied to GPF (41) in which the fine exhaust particles are accumulated. At this time, the temperature of GPF (41) is equal to or higher than a predetermined temperature. Thus, a deterioration in the exhaust gas purification performance of under-floor catalyst (33) at the time of the start of internal combustion engine (10) can be suppressed.Type: GrantFiled: June 13, 2019Date of Patent: February 6, 2024Assignee: NISSAN MOTOR CO., LTD.Inventors: Jin Yokoyama, Kouichi Murakami, Akikazu Sakai
