TRANSISTORIZED IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINES Russian patent published in 2006 - IPC F02P3/04 

FIELD: ignition system at accumulation of energy in inductance coil.

SUBSTANCE: proposed system is provided with moving-coil transducer and emergency vibrator used as switch gear in case of failure of transistor switch of pulse sensor. Proposed transistorized ignition system includes ignition coil, additional resistor, transistor switch, pulse sensor and emergency vibrator. Ignition system is additionally provided with change-over relay, transistor switch, integrating circuit, coincidence gate, capacitor and resistor. Make contacts of change-over relay are connected between primary winding of ignition coil and input of emergency vibrator and break contacts are connected between output of transistor switch and primary winding of ignition coil. Change-over relay winding is connected in circuit of transistor switch whose input is connected via integrating circuit with output of coincidence gate whose one input is connected with input of transistor switch and other is connected via capacitor with output of transistor switch. Transistor switch circuit is provided with resistor and is connected with outputs connected with primary winding of ignition coil. Ignition system operates in two modes and primary circuit current is interrupted by transistor switch controlled by pulse sensor or by emergency vibrator. At interruption of primary circuit current by vibrator, ignition system operates in mode of continuous sparking on spark plugs.

EFFECT: ease of use of ignition system.
