摘要： A gasoline powered boat safety ignition system has a start timer (U4,129) that requires the engine room blowers (22,138) to operate for a time prior to allowing engine start up. It has a second timer sequence that permits a hot or warm start shortly after the engine has been shut down without as much of a delay for blower operation as for a cold start. Also, the system has a timer that cyclically turns the blowers on for short periods while the engine is operating and has a switch (52,127) for overriding the safety system in case of an emergency.

摘要： 5 n7 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： A value approximately corresponding to the amount of a change in mean effective pressure calculated on the basis of the revolution period of an engine is used for discrimination of a misfire. In detecting a misfired cylinder by comparing this misfire discriminating value with a slice level, while a misfire detection during a coasting time is inihibited. Further, a misfire discriminating value corresponding to a misfired cylinder is verified on the basis of a predetermined varying pattern of the discriminating value. Further the slice level is set to the proper value in accordance with this discriminating value.

摘要： Engine speed variations following combustion events within the cylinders of a multi-cylinder internal combustion engine are compared with a threshold (12) during a predetermined number of combustion events. A distribution of speed variations exceeding the threshold with respect to the cylinders is formed (14). The distribution is analysed (17) to determine whether misfire is occurring, as indicated by speed variation following combustion occurring in half or less than half of the cylinders, or whether the vehicle is driving over a rough surface, as indicated by speed variation following combustion occurring in more than half of the cylinders.

摘要： An ignition system for a combustion-powered tool is powered by a battery (12) and is arranged so that a sudden discharge of a capacitor (36) produces a spark at a spark gap (32) of a spark plug (30). An oscillator (38) for charging the capacitor (36) is enabled if a trigger switch (16) is closed while a head switch (14) is closed, but not if the trigger switch (16) is closed while the head switch (14) is opened, and if a battery voltage, as monitored, is not less than a reference voltage, and so that a silicon-controlled rectifier (44), which is arranged to produce a sudden discharge of the capacitor (36), is switched to a conductive state if the capacitor voltage, as monitored, and is not less than a reference voltage. The head (14) and trigger (16) switches, which are photo-electric, are polled intermittently to determine whether they are closed. Predominantly, solid-state components are used.

摘要： A device for recognizing spark failures in an internal combustion engine has a sensor (15) for measuring the exhaust gas pressure and means (16, 17, 18) for recording the measurement value of the sensor during each cycle. Each exhaust gas pressure measurement value is compared with a corresponding expected value and an occurence signal is emitted when both values deviate from each other by more than a given difference. Means (21) for recognizing and processing failures determine the frequency of the occurrence signals and emit a failure signal when the frequency thus determined exceeds a threshold value. A warning light is switched on when the failure signal is emitted. This device for recognizing spark failures has a simple design, since the ignition in all cylinders of an internal combustion engine (11) can be monitored at the same time with a single sensor. The device can also detect failures in the exhaust gas duct (12), not only spark failures.

摘要： In a misfire detector for use in internal combustion engine having an ignition coil consisting of a primary coil and a secondary coil. An interrupter circuit on-off actuates primary current flowing through the primary coil. A series gap or check diode provided in a secondary circuit of the ignition coil. A spark plug is provided with an internal combustion engine. A voltage charging circuit works to electrically charge stray capacity inherent in the spark plug immediately after an end of the spark action of the spark plug. A secondary voltage detector circuit detects an attenuation time period of the secondary voltage and a distinction circuit determines on the basis of the attenuation time period whether or not the spark plug ignites air-fuel mixture injected in a cylinder of the internal combustion engine.
