    • A control device of an internal combustion engine performs an air-fuel ratio feedback control to set an air-fuel ratio to a target air-fuel ratio, and determines abnormality of a fuel system based on a feedback correction amount by the air-fuel ratio feedback control. The control device of an internal combustion engine includes: a double tank type oil pan including: an inner tank and an outer tank for storing oil; and a mechanism which switches between connection and disconnection of the inner tank and the outer tank; and a controller configured to control the mechanism to connect the inner tank and the outer tank in a case where the feedback correction amount is equal to or larger than a first predetermined value. Thus, it is possible to prevent the air-fuel ratio from getting rich, and it is possible to appropriately prevent the erroneous determination of abnormality of the fuel system.
    • 内燃机的控制装置进行空燃比反馈控制,将空燃比设定为目标空燃比,并且基于空燃比的反馈修正量来确定燃料系统的异常 反馈控制。 内燃机的控制装置包括:双罐型油盘,包括:内罐和用于储存油的外罐; 以及在内罐和外箱的连接和断开之间切换的机构; 以及控制器,被配置为在反馈校正量等于或大于第一预定值的情况下,控制连接内罐和外罐的机构。 因此,可以防止空燃比变浓,并且可以适当地防止燃料系统的异常的错误判定。

    • Cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors are disposed in each exhaust branch pipe connected to the cylinder groups, and a second air-fuel ratio sensor is disposed in a common exhaust pipe upstream from the catalyst. When a vapor amount introduced into an intake passage during purge control is determined, the vapor amount is determined during normal operation using output values from the first air-fuel ratio sensors and the vapor amount value learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor and the vapor amount value learned during rich-lean operation. Thereby, the vapor amount introduced into the intake passage when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined.
    • 内燃机的气缸被分成至少两个汽缸组。 第一空燃比传感器设置在与气缸组连接的每个排气支管中,第二空燃比传感器设置在催化剂上游的公共排气管中。 当确定在净化控制期间引入进气通道中的蒸汽量时,使用来自第一空燃比传感器的输出值和在正常操作期间学习的蒸气量值在正常操作期间确定蒸汽量。 在富稀的运行中,使用来自第二空燃比传感器的输出值和在富稀运转时学习的蒸气量值来确定蒸汽量。 由此,能够精确地确定从正常到内燃机的富含稀薄运转的状态进行开关时引入进气通路的蒸气量。
