摘要： Methods and systems are provided for inferring spark plug fouling due to accumulation of fuel additives thereon. In one example, an engine controller may infer spark plug hot fouling based on higher than expected exhaust temperatures by correlating the elevated exhaust temperature with late combustion phasing due to additive accumulation. A confidence factor of the spark plug hot fouling detection may be enhanced based on data regarding concurrent misfire and/or pre-ignition events.

摘要： In a control apparatus, a discharge control unit controls an igniter unit so that a flow of current from a primary coil towards a ground side is blocked, thereby generating a high voltage in a secondary coil, and controls a spark plug so that the spark plug generates electric discharge. An energy input control unit controls an energy input unit so as to input electrical energy to an ignition coil after the start of control of the spark plug by the discharge control unit. A control unit and an abnormality detecting unit detects an abnormality in the igniter unit or the ignition coil based on a first threshold and a first current value that is a value corresponding to a current detected by a current detection circuit at this time, when a first predetermined period elapses after the start of control of the spark plug by the discharge control unit.

摘要： A control apparatus for an internal combustion engine includes a crankshaft, a camshaft for actuating a valve of the engine, and a rotating electrical machine that is coupled to one of the crankshaft and the camshaft. The apparatus includes a computer that controls the rotating electrical machine. The rotating electrical machine includes a rotor and a plurality of rotation sensors, each of which outputs a signal corresponding to induced voltage generated by rotation of the rotor. The computer controls the rotating electrical machine based on the signals from the rotation sensors, and detects the occurrence of reverse rotation in the engine when an output pattern of the signals from the rotation sensors is different from an output pattern during forward rotation of the engine. As a result, the apparatus promptly detects the occurrence of reverse rotation of the internal combustion engine without providing additional sensors or rotors.

摘要： The present feature of the invention is generally directed to a subsystem of an ignition diagnostics and feedback control system using ionization current feedback. It utilizes the ionization signal from an ionization detection circuit to monitor ignition parameters, such as primary charge timing, primary charge duration, ignition/spark timing, and ignition/spark duration for future “smart” ignition system control. In addition, the ionization signal is also used to detect spark plug carbon fouling, as well as plug insulator overheating. These parameters can be monitored for every cylinder of the engine for each engine cycle.

摘要： A device for diagnosing the state of health of an ignition system is provided, where the system includes at least one spark producing channel comprising an exciter, output circuit and igniter plug. The device provides a diagnosis of the state of health for both the exciter and igniter plug by monitoring the high energy pulses at the output of the exciter. By monitoring the ignition system at an intermediate point in the system such as the output of the exciter, the sensor and electronics of the device may be completely contained within the electronic environment of the exciter, thereby avoiding any need for attaching sensors at the output of the system adjacent to the igniter plug in order to diagnose the plug's state of health. As an alternative to the device being built into the ignition system, it can be incorporated into automatic test equipment that produces high energy pulses for delivery to an igniter plug to be tested. The device is capable of diagnosing failure of either the exciter or the igniter plug and may also be configured to detect the impending failure of the plug.

摘要： In a method for protecting a catalytic converter from overheating, a conventional misfire recognition method is used to determine whether misfires are occurring in a cylinder. If this is the case, an attempt is made to interrupt the fuel supply to the affected cylinder. If this succeeds, the remaining cylinders are supplied with a lean mixture. If it does not succeed, all the cylinders are operated with a rich mixture. The lean setting of the mixture in the case of interrupted fuel supply to the affected cylinder has the effect that after the combustions in the cylinders, no further fuel reaches the catalytic converter which could combust in the catalytic converter with the oxygen induced by the affected cylinder.

摘要： A method of monitoring the operation of an internal combustion engine, such as is usable in a motor vehicle, combines the recognition of ignition failures with recognition of combustion failures. In one embodiment combustion failures are detected by the faltering of torque delivered by the engine. Ignition failures are electrically detected in terms of spark voltage or spark duration. In a first embodiment the rate of ignition and combustion failures is first compared with a predetermined threshold and if neither threshold is exceeded, the detection of an individual ignition failure is deemed plausible and is registered if detected. Only a failure rate in excess of a threshold results in cylinder-specific remedial measures to protect a catalyst in the exhaust system. In a second embodiment, unlike the first, only an ignition failure results in a cylinder-selective remedial action.

摘要： A method and apparatus for detecting engine overheating and controlling engine ignition timing utilizes a single temperature sensor. The temperature sensor is positioned adjacent a cylinder head of an engine. A rate of engine temperature increase is calculated based on engine temperature information produced by the temperature sensor, and engine speed is regulated based on the calculated rate of engine temperature increase. Ignition timing is also controlled in response to the engine temperature information produced by the temperature sensor, and the engine speed is regulated to a predetermined speed value whenever the engine temperature exceeds a predetermined temperature value.
