摘要： PROBLEM TO BE SOLVED: To improve detection accuracy of an air-fuel ratio sensor between a plurality of cylinders.SOLUTION: As for two cylinders (#2, #4) having the shortest intervals of arrival timing of exhaust gas to a detection point of an A/F sensor, whether a fault of an air-fuel ratio occurs in any of the two cylinders is detected. When the fault occurs, which of the two cylinders causes the fault is discriminated (S230). Exhaust from the cylinder (#4 cylinder) in which exhaust gas arrives earlier of the two cylinders does not mix exhaust from the other cylinder and has slow flow velocity, while exhaust from the cylinder (#2 cylinder) in which exhaust gas arrives later mixes exhaust from the former (#4 cylinder) and has relatively large exhaust flow rate and flow velocity. Generally, as flow rate becomes less and flow velocity becomes slow, a flow of exhaust gas in an exhaust passage becomes unstable and variation in detection values becomes large. Accordingly, which of the two cylinders causes the fault can be discriminated on the basis of values of variation in air-fuel ratio outputs from the two cylinders.
摘要翻译：要解决的问题：提高多个气缸之间的空燃比传感器的检测精度。解决方案：对于具有到A / F传感器的检测点的排气到达时间的最短间隔的两个气缸（＃2，＃4），空燃比的故障是否发生在检测到两个气缸。当发生故障时，鉴别出两个气缸中哪一个导致故障（S230）。排气从两个气缸之前到达的气缸（＃4气缸）的排气不会混合另一个气缸的排气并具有缓慢的流速，而来自排气到达的气缸（＃2气缸）的排气混合后前排（＃4气缸）排气，排气流量和流速相对较大。通常，随着流量变少并且流速变慢，排气通道中的废气流动变得不稳定，并且检测值的变化变大。因此，可以基于来自两个气缸的空燃比输出的变化值来区分导致故障的两个气缸中的哪一个。版权所有（C）2013，JPO＆INPIT
