Abstract: An ignition wiring system having the leads formed as a wire coil about a magnetizable core defines a distributed constant resistive-inductive series impedance. A metal shield is located over the spark plug proper and electrically connected to the engine ground. A flexible shield extension in the form of a coil extends over the lead from beneath the shield. The shield and shield extension introduce distributed capacitance between the special lead and engine ground. The combination of the shield and shield extension with the special lead forms a distributed constant RLC filter which produces RFI suppression. The shield and shield extension confine the electromagnetic radiation emanating from that portion of the lead where the radiation is strongest, thereby enhancing the suppression. The rapid discharge by the spark plug of the stored energy contained in the distributed capacitance increases the spark intensity and promotes more complete combustion.

Abstract: A self-protective driver circuit with automatic reset features is provided for a marine electric fuel pump (2, 102) energized by the boat battery (4, 104) as controlled by a series connected semiconductor switch (6, 106). A first stage protective subcircuit (28, 128) senses surge current through the semiconductor switch at initial turn on with the fuel pump at rest and causes the semiconductor switch to depart from saturated conduction and thus limit the current until the pump starts running and the current decreases to a safer level, to protect the semiconductor switch from excessive current. A second stage protective subcircuit (36, 136) senses a given minimum current flow through the semiconductor switch in combination with abnormally high conduction voltage across the semiconductor switch, indicating a stalled or electrically shorted fuel pump, and in conjunction with a timer (58, 164) quickly turns OFF the semiconductor switch for a given time interval for cooling-off purposes, after which the semiconductor switch is automatically turned back ON, with the cycle repeating as necessary. A third stage protective subcircuit (82, 184) senses long term increased current flow through the semiconductor switch indicating a deteriorating condition in the fuel pump, and in conjunction with the timer turns OFF the semiconductor switch for the given time interval after which the semiconductor switch is automatically turned back ON to re-energize the fuel pump, the cycle repeating as necessary.

Abstract: A voltage regulator for an internal combustion engine having a permanent magnet alternator and utilizing an SCR/diode bridge rectifier includes crowbar SCR overvoltage protection means. To assure that the crowbar SCR has an adequate period in which to cool off after being triggered on by an overvoltage surge, crowbar SCR operation is detected to generate a control signal to activate a timer which shuts off gate drive to the main bridge SCR's and thereby shuts down the bridge for a period of time sufficient to provide crowbar SCR recovery and cool off. In its preferred embodiment, the control signal is provided by the crowbar SCR gate to cathode voltage drop during protective operation, which signal is of relatively long duration, thus allowing the use of filters to eliminate spurious triggering of the timer by transient noise signals. Feedback from the switch means supplying gate drive to the bridge SCR's is used to provide a tapered charging characteristic. Temperature detection of the mounting base temperature of the semiconductors in the SCR/diode bridge may be used to shut off the gate drive to the main bridge SCR's to prevent excessive temperature rise of the semiconductor junctions.

Abstract: The invention provides a modular ignition system using a separate ignition module (16) for each engine cylinder. The modules (16) can be arranged for use with engines having differing numbers of cylinders.Each module (16) includes a main capacitor (22) to be charged by the engine's alternator (11). The main capacitor (22) is discharged through a main silicon controlled rectifier (23) into an ignition transformer (28) to provide a high voltage pulse to fire a spark plug (15). A pilot capacitor (26) is also charged by the alternator (11) to provide power to a pilot SCR (36). The pilot SCR (36) has its gate connected to a trigger winding (14) in the alternator (11) to discharge the pilot capacitor (26) into the gate of the main SCR (23) to fire the spark plug (15).The pilot capacitor (26) is also connected to the cathode of the main SCR (23). This connection raises the voltage level of the pilot capacitor (26) during the discharge pulse to assure gate current to the main SCR (23) during the critical turn on period.A biasing network including resistors (39, 40) and a bias capacitor (41) is provided in each of the modules (16) to maintain a substantially constant ignition angle, regardless of engine speed. The biasing networks can be interconnected to assure uniform timing for all of the spark plugs (15).

Abstract: A tachometer circuit for an engine having an alternator driven capacitive discharge ignition system functions as a frequency-to-current converter converting each ignition capacitor discharge into a precisely controlled amount of electric charge, which is then passed thru an indicating microammeter movement graduated in RPM. The precisely controlled electric charge is developed in a charge transfer capacitor, with the peak voltage appearing across the capacitor being regulated by a programmable transistorized voltage regulator. The temperature coefficient of the charge transfer capacitance is neutralized by the temperature coefficient of the voltage regulator, such that the product of capacitance multiplied by voltage--which is equivalent to charge--remains constant. The precisely controlled charge is initially established by machine trimming of a voltage--determining resistor in the voltage regulator, thereby allowing practical large volume manufacture of the circuit from unmatched components.

Abstract: A two cylinder, two cycle engine for an outboard motor includes an alternator driven, capacitor discharge ignition system. The alternator includes an annular permanent magnet secured within a flywheel skirt and includes a pair of circumferential opposite poles with diametrical spaced neutral areas. The magnet is a flexible ferrite strip with a butt joint at one of the neutral areas. A stator assembly is mounted within the annular rotor and includes a semicircular core with a charging coil at each end. Each movement of the magnetic gap means past the coils generates a pulse. A trigger coil within a housing is mounted in coplanar relation between the charging coils, with a pole aligned with and spaced from the stator core. The housing is rotatably mounted and includes an integral cam for positioning a throttle lever. A pair of capacitors are connected in parallel to the charging coils through steering diodes such that the one capacitor is charged from one of the polarity pulses while the other capacitor is charged from opposite polarity pulses. A common gated controlled rectifier is connected in a discharge path for both of the capacitors through individual pulse transformers and isolating diodes. Only the charged capacitor provides energy through its pulse transformer. A full wave rectifier rectifies each trigger pulse and is connected by a trigger circuit to the gate of the controlled rectifier.

Abstract: In an internal combustion engine an automatic fuel pump switch connects a fuel pump motor to the battery. An electronic sensing circuit is connected to the output winding of an engine-driven alternator which is also connected to charge the battery. The sensing circuit includes a sensing transistor connected to continuously sense the two instantaneous voltages relating to ground that appear as alternating current (A.C.) voltages at the opposite ends of the alternator output winding and produces an output only when one voltage is above a selected positive level while the other voltage is lower than the first voltage by a minimum amount. A control transistor circuit is connected to the output of the sensing transistor and is turned on to operate the fuel pump only when the engine is turning over at a sufficient rate to start and run.

Abstract: An alternator driven capacitive discharge ignition system includes a tachometer circuit monitoring the speed-dependent repetition rate of discharge at an internal trigger power supply, the tachometer circuit causing the triggering threshold bias to be reduced below idle speed to electronically advance the timing. The ignition circuit includes a triggering threshold bias capacitor in series the trigger pulse source and a trigger power supply having a pilot capacitor to alternately fire a pair of ignition silicon controlled rectifiers. The pilot capacitor is charged in series with an RC filter network of a "bucket" tachometer circuit to create a speed signal voltage proportional to engine speed with the pilot capacitor functioning as the bucket capacitor. The speed signal is a voltage which is positive relative to a common signal ground while the threshold bias capacitor voltage is negative relative to such signal ground. The speed signal is applied to the gate of a P-channel depletion-mode junction field-effect transistor (JFET). The source-to-drain channel of the transistor is connected in parallel with the threshold bias capacitor. Below a selected idle speed, the source-to-drain channel resistance provides a maximum bleed current to the threshold bias capacitor, thereby reducing the triggering threshold voltage and creating an automatic spark advance. As the engine speeds up, the source-to-drain resistance increases and virtually eliminate the bleed current at speeds slightly above idle.
