AUTOMOBILE IGNITION SYSTEM Russian patent published in 2007 - IPC F02P1/00 

FIELD: automotive industry; automobile electrical equipment.

SUBSTANCE: invention relates to electric devices provides operation of internal combustion engines and it can be used in production and operation of automobiles. Proposed ignition system of internal combustion engine contains ignition coil, distributor connected with secondary winding of coil, spark plugs connected with distributor, electronic current breaker of coil primary winding, engine cylinder piston position pickup connected with breaker and mechanically connected with distributor shaft. System is furnished additionally with pressure transmitter arranged in engine cylinder, comparator, phase-amplitude converter controlled by pulse generator with phase shifter. Position pickup is provided with three induction windings having phase angles corresponding to top dead center (TDC)of piston in cylinder, before and after TDC, winding of pickup with phase before TDC is connected with input of phase shifter whose output is connected with input of electronic current breaker, winding of position pickup with phase after TDC and pressure transmitter are connected with inputs of comparator whose outputs is connected with input of phase-amplitude converter, output of the latter being connected with control input of generator with phase shifter, and pickup with phase of TDC is connected with synchronizer which is connected with synchronizer inputs of generator and comparator. Invention is aimed at increasing economy of engine and is based on electronic adjustment of moment of maximum detonation of working mixture in engine cylinder with position of piston providing maximum conversion of burning energy into mechanical energy of engine rotation.

EFFECT: increased economy of engine.
