| Number | Title | Issue Date |
| 6845763 | Vehicle ignition system using ignition module with reduced heat generation An ignition system for a vehicle includes a distributor having with a Hall Effect stator assembly and ignition module formed preferably as a thick film integrated (TFI) module, which receives a spark output (SPOUT) signal from an electronic control assembly (ECA). T... | 01/25/2005 |
| 6837229 | Ignition device for internal combustion engine The ignition device for an internal combustion engine includes two spark plugs provided for each cylinder, ignition coils arranged independently to each of the spark plugs, an ignition power source circuit for supplying electrical energy to first coils which constit... | 01/04/2005 |
| 6216678 | Method and apparatus for generating and identifying misfires An engine cylinder firing event is intentionally defeated by clipping the flyback voltage of the ignition system primary coil winding under the control of a misfire generator that develops a misfire logic signal from ignition dwell events and user inputs ... | 04/17/2001 |
| 4886036 | Method and arrangement for generating ignition sparks in an internal combustion engine In a capacitive ignition system for an internal combustion engine, the discharging and charging of an ignition capacitor is controlled by a control unit which actuates a first circuit-breaking element in a discharging circuit and a second circuit-breaking... | 12/12/1989 |
| 4552119 | Magnetic pulse timer Improved magnetic pulse timer components provide increased timer voltages with steeper bipolar waveforms. Such improvements are residual in terms of a permanently magnetized timer rotor (30, 40, 60, 70, 80). Rotors (30, 40, 60) have regularly spaced protr... | 11/12/1985 |
| 4537175 | Bipolar magnetic pulse activated ignition system An ignition system for a fuel burning engine has a transformer with a primary winding (L1) and a secondary winding (L2). A magnetic pulse time (20) provides a bipolar signal to the input circuits of a pair of transistors (Qa-Qb, Qn-Qp, Q2-Q3, Q4-Q5, Q6a-Q... | 08/27/1985 |
| 4336785 | Magneto ignition with field-responsive biasing A magneto ignition system having inherent means for providing operating biases for components thereof at temperature extremes is disclosed. The disclosed ignition system includes an ignition coil (10) having primary and secondary coil (12, 14) a solid sta... | 06/29/1982 |
| 4305371 | Contactless ignition circuit for internal combustion engines This invention relates to a contactless ignition circuit for internal combustion engines characterized in that a primary short-circuiting current flowing through the primary winding of an ignition coil is made to flow through a power transistor controlled... | 12/15/1981 |
| 4167928 | Electronic distributor with a decreased number of power switches For a four cylinder engine, a first and second ignition coil, each having a primary and secondary winding is provided. A first and second electronic switch is connected in series wit the primary winding of each ignition coil and the so-formed series circu... | 09/18/1979 |
| 4019486 | Motor ignition system with magnetically selectable gas discharge devices A magnetic field, such as produced by a surrounding coil, lowers the breakdown voltage of a gas discharge device in series with a spark plug so that the ignition voltage will preferentially go to that spark plug rather than to others in series with gas di... | 04/26/1977 |
