Abstract: A circuit to achieve a large ignition advance, limitation of speed of revolutions and to prevent backfiring and reverse direction running in a magnetic ignition system that comprises a flywheel with two poles and a three-legged iron core. An ignition transformer (L3/L4), a triggering coil (L2) and a charging coil (L1) are arranged on the legs of the core. The triggering coil is arranged either on the first or second leg in the direction of rotation of the flywheel, and the charging coil on the final leg. A time-constant circuit (an RC net) and a control switch (T2) are arranged between the charging coil and a main switch (T1) that opens/blocks triggering pulses whereby limitation in the speed of revolutions is achieved by means of adjustment of the time-constant circuit.

Abstract: A control system for an engine or exhaust system includes a sensor that detects an exhaust gas temperature and a sensor that detects an exhaust coolant temperature. The sensors communicate with a controller. Based upon the output from the sensors, the controller determines whether each sensor is functioning properly and whether the cooling system is functioning properly. In the event of a malfunction of a sensor or the cooling system, an alarm is issued and the speed or operation of the engine is altered. In addition, if the controller detects a problem with the coolant system based upon coolant temperature or with the coolant temperature sensor, then the controller disables a starter motor such that the engine cannot be restarted without resetting the starter motor. The start motor can be disabled through a relay and the relay can be reset manually or automatically after a preset period of time.

Abstract: A system is provided for preventing spark-on-make in an internal combustion engine, using manifold pressure information. The system includes a pressure sensor and a controller. The pressure sensor is adapted to detect pressure in an intake manifold and provide an output signal indicative of that pressure. The controller is at least indirectly connected to the pressure sensor and is adapted to delay initiation of ignition dwell in a coil by a period of time sufficient to avoid spark-on-make, in response to the output signal from the sensor. Preferably, the pressure sensor is a manifold absolute pressure (MAP) sensor. The controller preferably is implemented by suitably programming or otherwise configuring an electronic engine control unit (ECU). Also provided is a method for preventing spark-on-make in an internal combustion engine.

Abstract: For detecting a backward revolution of a revolving component of an internal combustion engine, with a sensor which senses a revolving component having at least one angular mark, the backward revolution is assumed when a prescribable value between two pulses of the signal of the sensor is exceeded, and stalling is detected after it is ensured that the backward revolution of the internal combustion engine has taken place, and outputting of further injections and/or ignitions is suppressed until a resynchronization of the system takes place after a prescribable time has passed.

Abstract: A gasoline powered boat safety ignition system has a start timer that requires the engine room blowers 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 for overriding the safety system in case of an emergency.

Abstract: A warning system for warning a lack of a working fluid for an engine. The engine is provided with an ignition unit supplied with an ignition power supply from a magneto. A sensing unit senses the lack of the working fluid and produces a detection signal. A warning element, connected to the magneto, receives a power supply to give a warning indicating the lack of the working fluid. A controller is responsive to the detection signal from the sensing unit for actuating the warning element to provide the warning without deteriorating a performance of the ignition unit.

Abstract: The invention is a further development of an earlier arrangement of r.p.m. limitation (SE-P-452 355). The advantage of this invention is that the adjustment of pulse times is eliminated. The arrangement can be manufactured without cost demanding adjustment as the circuit is crystal-controlled which involves a great accuracy. As the r.p.m. increases, the pulse t.sub.2 of the second flip-flop comes closer to the next ignition pulse of the ignition system and, at the limitation speed, t.sub.2 begins to overlap the ignition pulse. The ignition time T is delayed and an ignition delay takes place with a subsequent limitation of the r.p.m.

Abstract: An engine speed limiter includes a computing means for computing a value that is functionally related to the time between successive ignition pulses and for outputting a speed signal representative thereof. The speed limiter also includes generating means for generating a reference signal that is functionally related to the desired maximum limit speed. A comparison means compares the speed signal with the reference signal and generates a limit signal if the result of the comparison indicates that the actual engine speed is about equal to or greater than the desired maximum limit speed. The limit signal is used to interrupt engine ignition to thereby limit engine speed.

Abstract: An ignition system for an internal combustion engine, such as an outboard marine engine, which includes an advanced timing schedule, a non-advanced timing schedule, and a circuit for switching between the two schedules or disabling both schedules based upon engine operating conditions. The ignition system includes an optoelectronic time base generator which produces two sets of timing pulses relative to crankshaft position which are non-advanced timing pulses and advanced timing pulses. The time base generator comprises a LED-phototransistor pair and an encoder disk attached to the crankshaft with slots to interrupt the emission path between LED-phototransistor pair. The non-advanced pulses are generated based upon the trailing edge of each slot while the advanced pulses are generated based up the leading edge, wherein the width of the slots indicate the degree of advancement of the advanced schedule over the non-advanced schedule. Both schedules are inhibited based on a high overspeed condition and a low overspeed condition when the engine is overheated, wherein there is a smooth transition between the two conditions.
