    • A control device of an internal combustion engine includes: an internal combustion engine that has an exhaust valve; an exhaust passage that is connected to the internal combustion engine; a turbine of a supercharger that is provided in the exhaust passage; a bypass passage that bypasses the turbine; a bypass valve that opens and closes the bypass passage; a valve-operating device that is capable of switching between a first mode and a second mode, the first mode being a mode in which the exhaust valve is opened at least in a part of an exhaust stroke, the second mode being a mode in which the exhaust valve is opened at least in a part of the exhaust stroke, a lift amount of the exhaust valve is increased at least in a part of an intake stroke and the exhaust valve is closed after that; and a controller that switches a mode to the second mode and closes the aperture of the bypass valve, or controls the aperture of the exhaust valve to a smaller side than an aperture of the bypass valve of the first mode.

    • A method for operating a multi-cylinder internal combustion engine (13) includes controlling opening of intake or exhaust valves (18, 24), via a step of generating a control current in a control circuit (52) for an electrical actuator (20) coupled with the valve (18, 24). The control circuit (52) is then monitored for an induced current that differs from the control current, and a signal outputted that is indicative of valve performance responsive to monitoring the control circuit (52). Another operating method includes determining engine valve performance and also trimming an engine valve (18, 24) based on one signal which is indicative of valve performance. An internal combustion engine (13) includes an electrical actuator (20) configured to control opening or closing of one of an intake valve (18) and an exhaust valve (24). An electronic control module (40) is configured via a software fault detection routine to determine a performance condition of an intake or exhaust valve (18, 24) in the engine (13) via monitoring a control circuit (52) for induced currents when an electrical actuator (20) coupled with the intake or exhaust valve (18, 24) is de-energized.
    • 一种用于操作多缸内燃机(13)的方法包括:通过在用于电致动器(20)的控制电路(52)中产生控制电流的步骤来控制进气门或排气门(18,24)的打开, 与阀(18,24)联接。 然后监控控制电路(52)的感应电流,该感应电流不同于控制电流,并且响应于监控控制电路(52)而输出表示阀性能的信号。 另一种操作方法包括基于指示阀性能的一个信号来确定发动机气门性能以及修整发动机气门(18,24)。 内燃机(13)包括被配置为控制进气门(18)和排气阀(24)之一的打开或关闭的电致动器(20)。 电子控制模块(40)经由软件故障检测程序来配置,以通过在感测电流(52)中监测感应电流的控制电路(52)来确定发动机(13)中的进气门或排气门(18,24)的性能状况, 与进气门或排气门(18,24)联接的电致动器(20)被断电。
