  • Ignition systems and fuel injection systems for internal combustion engines
    Patent number: 3981282
    Abstract: The advance and retard of the spark ignition in an ignition system of an internal combustion engine is achieved electronically by generating two series of pulses in synchronism with the engine using one series as a reference for maximum advance and the other series to operate a counter to count down the requisite number of pulses beyond the maximum advance point before the spark is initiated, the count of the counter being varied from a computer in accordance with speed and/or load on the engine.
    Type: Grant
    Filed: January 8, 1973
    Date of Patent: September 21, 1976
    Assignee: Lumenition Limited
    Inventor: Eric Harold Ford
  • Combustion detector for internal combustion engines
    Patent number: 3978720
    Abstract: Detection of the combustion within a cylinder of an internal combustion engine by sensing the visible and/or infra-red radiation emitted on combustion by means of a quartz window in the cylinder wall or head, a fiber optic light guide and a photo-transistor. The detection may be utilized in ignition timing, or determining engine R.P.M. or cylinder misfire.

  • Fuel injection systems for internal combustion engines
    Patent number: 3945350
    Abstract: The quantity of fuel injected in a fuel injection system of an internal combustion engine is achieved electronically by generating two series of pulses in synchronism with the engine using one series as a reference for maximum advance and the other series to operate a counter to count down the requisite number of pulses beyond the maximum advance point before the fuel injection is initiated, the count of the counter being varied from a computer in accordance with speed and/or load on the engine.
