Abstract: A self-diagnosing apparatus for a vehicles capable of reliably storing diagnostic data on high priority malfunctions. A control unit comprises a CPU and a RAM for storing stores contents even when an ignition key is turned off. The self-diagnosing apparatus detects a plurality of malfunctions. The plurality of malfunctions are classified into high priority malfunctions and low priority malfunctions. The RAM has a plurality of storage areas including a first frame and a second frame, the first frame being made to correspond to high priority malfunctions and the second frame to low priority malfunctions. The CPU inputs diagnostic data from each section of the motor vehicle necessary for analyzing instrument malfunctions and updates the stored contents of each area of the first and second frames. When the CPU detects an instrument malfunction, it sets a malfunction code at the beginning area of the frame corresponding to the priority at which the instrument malfunction is classified, and inhibits subsequent updating of the stored contents. Therefore, diagnostic data is stored for each priority.

Abstract: Monitoring apparatus is provided for the ignition system of an internal combustion engine such as is provided in a motor vehicle, which is capable of detecting a variety of malfunctions of ignition under a variety of engine operating ranges, so that the catalyst used in the exhaust system of the engine can be protected by setting lambda=0 and/or cutting off fuel injection to an inoperative cylinder, in as many instances of malfunction as possible. Various methods of monitoring are available and are correlated for selection in accordance with the different operating ranges of the engine. The ignition spark duration and the ignition discharge voltage are measured for individual sparks on the primary side of an ignition coil and are compared with limit values for correct ignition, these limit values being selected from a memory in accordance with the particular range of operating conditions in which the engine is operating. If the quality of malfunction detection is not good enough for individual ignition deficiencies to be reliably detected, deficiencies that are periodically recurrent or abnormally bunched are detected on a statistical basis.

Abstract: There is described a motor vehicle having a spark ignition engine in an engine compartment and having automatic advance and retard device to advance or retard the angle of the firing of the spark relative to the top dead center of the pistons in the cylinders of the spark ignition engine. The engine has a control device including a microphone carried on a vibration damping mounting on the vehicle close to the engine to detect sounds emitted during the running of the vehicle. A frequency filter is connected to the microphone connected to the detector to permit transmission of sound only in a narrow band of sound frequencies between 4,000 and 20,000 Hz which correspond to the sound range of sounds caused by knock. The output from the filter is compared with a datum and when this exceeds such datum, the automatic advance and retard is retarded to prevent knock continuing.

Abstract: An engine control system of a marine outboard engine has an oscillator which operates in response to an abnormality signal resulting from detection signals from an oil level sensor and a temperature sensor, and in response to a signal from a tachometric sensor to transmit normal and retarded ignition signals alternately and repeatedly to a firing timing control circuit, which thereupon controls the engine ignition with normal firing timing when receiving the normal ignition signal and with retarded firing timing when receiving the retarded ignition signal. The engine power output under retarded firing time is lower than that under normal firing timing, whereby the engine emits an abnormal humming sound, warning the operator that an abnormal condition has occurred.

Abstract: To permit continued operation of a vehicle in spite of malfunction of an electronic ignition computer system, or any other electronic control module in an automotive vehicle, a transducer (10) provides an output to a trigger stage which has its output connected a digitally operating microprocessor (17) and to a bypass or transfer switch (21). The output from the microprocessor is connected to an analog and operating output stage (19, 20) to be controlled by the digital system of the microprocessor (17). Upon sensing of low operating voltage (U) as determined, for example, by a threshold switch (22), or of starting condition the switch (21) is closed, bypassing or interrupting connection to the microprocessor, and directly connecting signals from the transducer output stage to the input of the ignition circuit to permit operation under emergency conditions. The analog portion of the system is a single integrated module, separate from the digitally operating microprocessor (17) for ease of error diagnosis, maintenance and repair. This is particularly important with digitally operating control systems (17) which are subject to malfunction under low voltage conditions or upon occurrence of stray or distrubance signals in the network, for example under starting conditions.
