摘要： A device according to an aspect of the invention detects abnormality of spark plugs of an internal combustion engine. A value related to electric resistance across a gap between electrodes of each spark plug is measured. Next, it is determined whether or not the measured value, related to the electric resistance, assumes a value indicating that the electric resistance is below a predetermined value, when the engine is determined to be in a non-combustive state. The spark plug is determined to be abnormal when it is determined that the measured value, related to the electric resistance, assumes the value indicating that the electric resistance is below the predetermined value. A misfire-detecting system according to another aspect of the invention incorporates the above device.

摘要： A misfire-detecting system for an internal combustion engine detects occurrence of a misfire in the engine, based on voltage between both ends of a spark plug assumed when sparking discharge takes place at the spark plug. A diode is arranged in an ignition secondary circuit of the engine, for checking reverse current flowing in the circuit in a direction reverse to the direction of flow of current occurring when spark ignition takes place at the spark plug. An ECU detects reverse current flowing in the ignition secondary circuit, and detects an abnormality of the diode, based on the detected reverse current.

摘要： A system and method for detecting a failure occurring in an exhaust secondary air supply system of an internal combustion engine. A conduit is connected to the exhaust pipe to supply secondary air to the exhaust pipe to promote oxidization of the emissions in the exhaust gases. A valve is provided in the conduit for opening/closing it. The failure of the valve is detected by operating the air pump to supply the air in the conduit, while closing the conduit by the valve. The air/fuel ratio is detected by an oxygen sensor installed downstream of the conduit to be compared with a desired air/fuel ratio. If the detected air/fuel ratio is leaner than a desired air/fuel ratio, the air flows to the exhaust pipe so that the valve is considered to be stuck to open. Alternatively, a pump current is detected and is compared with a reference value indicative of the current at no air flow. If the detected current is less than the reference value, the valve is considered to be in failure. Moreover, the movement of a valve member is sensed to detect whether the valve is stuck to close.
摘要翻译：一种用于检测在内燃机的排气二次空气供给系统中发生的故障的系统和方法。导管连接到排气管，以向排气管提供二次空气以促进废气中的排放物的氧化。管道中设有阀门，用于打开/关闭阀门。通过操作气泵来检测阀门的故障，以便通过阀门关闭导管时在管道中供应空气。空气/燃料比由安装在管道下游的氧传感器检测，以与期望的空气/燃料比进行比较。如果检测到的空气/燃料比比期望的空气/燃料比更稀，则空气流向排气管，从而认为该阀被打开。或者，检测泵电流并将其与表示无气流的电流的参考值进行比较。如果检测到的电流小于参考值，则认为阀门处于故障状态。此外，检测阀构件的移动以检测阀是否被卡住以关闭。

摘要： A control system controls an electrically heated catalyst for purifying exhaust gases emitted from an internal combustion engine. Voltage applied to the electrically heated catalyst and electric current flowing through the same are detected. A changeover is made between supply and interrupt of power to the electrically heated catalyst. A parameter indicative of an operative state of the electrically heated catalyst is calculated based on the detected voltage and the detected current, and the operative state of the electrically heated catalyst is detected based on the parameter. The changeover between the supply and interrupt of power to the electrically heated catalyst is controlled based the operative state of the electrically heated catalyst thus detected.

摘要： An internal combustion engine has an adsorber arranged in the exhaust passage for adsorbing unburnt components in exhaust gases, and an exhaust gas-purifying device arranged in the exhaust passage at a location downstream of the adsorber. The exhaust gas-purifying device is equipped with a heater. An ignition timing of an internal combustion engine is retarded when the engine is started at a low engine temperature. The retardation of the ignition timing is restrained over a time period from the start of the engine to a time point the exhaust gas-purifying device is warmed up to a predetermined activated condition.
