IGNITION SYSTEM ELECTRONIC CORRECTOR Russian patent published in 2001 - IPC

FIELD: transport engineering; automobile ignition system. SUBSTANCE: proposed corrector has parametric voltage stabilizer whose inputs are placed between first and second supply buses. It has also series-connected time delay unit with two inputs, first power amplifier and power transistor switch. According to invention the following elements are placed additionally into proposed corrector: direct current stabilized voltage converter, breaker contacts chatter suppressor, ignition advance angle correcting pulse shaper with two outputs, ignition coil primary winding current accumulation time pulse shaper, second power amplifier and second power transistor switch. Time delay unit is provided with second out put, and power amplifier, with second input. Inputs of voltage converter and chatter suppressor are connected with device input/output and their outputs, with output of second switch and first input of time delay unit, respectively. Second input and output of time delay unit are connected, respectively, with first output and input of correcting pulse shaper whose second output is connected through series-connected accumulation time pulse shaper and second amplifier with input of second switch. Second input of first amplifier is connected to device input/output. EFFECT: improved reliability. 8 cl, 2 dwg
