FIELD: motor car construction. ^ SUBSTANCE: invention relates to automobile industry, particularly to electrical equipment of motor vehicles and sparking processes in internal combustion engine. Ignition system of internal combustion engine, consisting spark (9) plugs, voltage distributor (8), ignition coil (7), transistored commutator (6), power supply, sensor of electric signals (1), implemented in the form of stator (2) and rotor (3). Rotor (3) is mechanically connected to distribution shaft of motor. Stator (2) and rotor (3) of sensor (1) are implemented with two insulated segment cylindrical plates (4) and (5). Rotor plates (5) are connected to each other. One plate (4) of stator (2) is connected to power supply, and the second plate (4) of stator (2) is connected to input stage of commutator (6) and through additional resistance R1 to ground. Input stage of commutator (6) is implemented on the field-effect transistor VT. ^ EFFECT: design simplification of ignition system with transistor commutator, reduction in value and reliability improvement of its operation. ^ 1 dwg |
