AUTOMOBILE IGNITION SYSTEM Russian patent published in 2011 - IPC F02P5/06 F02P5/15 

FIELD: engines and pumps.

SUBSTANCE: automobile ignition system includes the following: position sensor (1) of piston in cylinder (11), pulse shaper (4), controlled delay element (5), shaping amplifier (6), disjunctor (7), ignition transformer (8), high voltage distributor (9) and in-series connected ignition plugs (10), as well as clock-pulse generator of reference frequency (12), pulse counter (13), memory register (15), element of fixed delay (14) and inertia-free non-linear converter (16). Inverting input of pulse counter is connected to output of reference frequency pulse generator (12), zero setting input is connected to input of fixed delay element (14), and output is connected to information input of memory register (15). Memory register recording input (15) is connected to output of pulse shaper (4) and to input of fixed delay element (14). Input of inertia-free non-linear converter (16) is connected to output of memory register (15), and output is connected to control input of controlled delay element (5). Controlled delay element (5) consists of clock-pulse generator of reference frequency (5.1), logic OR element (5.2), pulse counter (5.4) and code comparator (5.4). The first input of code comparator (5.4) is connected to output of pulse counter (5,3); the second one is control input of delay element (5), and output is output of delay element (5) and is connected to the first input of OR element (5.2). The second input of OR element (5.2) is signal input of delay element (5), and output is connected to input of zero setting of pulse counter (5.3). Inverting input of pulse counter (5.3) is connected to output of clock-pulse generator (5.1).

EFFECT: higher operating reliability of the system at change of advance angle of ignition for various angular speeds of crankshaft.
