    • A torque estimating system for an internal combustion engine including a plurality of cylinders is provided that is capable of accurately estimating torque for each cylinder.A cylinder pressure of a CPS-mounted cylinder #1 is acquired (step 100). Measured indicated torque Te1 resulting from an explosion in the CPS-mounted cylinder #1 is calculated based on the cylinder pressure (step 102). A first angular acceleration dω1/dt and a second angular acceleration dω2/dt are calculated (steps 104 to 106). Estimated indicated torque Te2 resulting from an explosion in a CPS-less cylinder #2 is calculated using the measured indicated torque Te1 of the CPS-mounted cylinder #1 and a difference value between the second angular acceleration dω2/dt and the first angular acceleration dω1/dt (step 108). If a cylinder pressure sensor is to be disposed in a plurality of cylinders, cylinders in which the CPS is disposed are set such that the number of cylinders in which the explosion takes place between the cylinders having the CPS is equal.
    • 提供一种用于包括多个气缸的内燃机的扭矩估计系统,其能够精确地估计每个气缸的扭矩。 获取安装有CPS的气缸#1的气缸压力(步骤100)。 基于气缸压力计算由CPS安装的气缸#1中的爆炸产生的测量的指示转矩Te1(步骤102)。 计算第一角加速度dω1/ dt和第二角加速度dω2/ dt(步骤104至106)。 使用CPS安装的气缸#1的测量指示转矩Te1和第二角加速度dω2/ dt与第一角加速度dω1之间的差值来计算由无CPS气缸#2中的爆炸产生的预计转矩Te2 / dt(步骤108)。 如果将气缸压力传感器设置在多个气缸中,则设置CPS的气缸被设定为使得在具有CPS的气缸之间发生爆炸的气缸数相等。

    • A first cell having an electrolyte and a pair of electrodes on the surface of the electrolyte with one of the electrodes facing a gas chamber causes, upon receipt of an applied voltage, a current to flow in accordance with the amount of oxygen discharge while discharging oxygen from the chamber. An open-circuit-induced fault is detected in accordance with a current flow change that is caused by the first cell when the voltage applied to the first cell reverts to a reference level after a temporary deviation from the reference level. A second cell generates a signal in accordance with the oxygen concentration in the measurement target gas chamber. An open-circuit-induced fault is detected in accordance with a signal change that is generated from the second cell when the voltage applied to the first cell reverts to a reference level after a temporary deviation from the reference level.
