FIELD: rocket and space vehicles, transport engineering; automatic electronic devices. SUBSTANCE: proposed device is designed for use in any vehicles where reliable ignition of fuel mixtures in wide range of ambient temperatures should be provided. System has spark plugs, noncontact pickup connected through transistor switch to common terminal of ignition coil. Photon-coupled pairs and shift register are introduced into system. Input of shift register is connected to output of noncontact pickup. Outputs of shift register are connected to supply source minus terminal through light- emitting diodes of photon-coupled pairs and resistors. First terminals of output elements of photo-coupled pairs are connected to each other and to output of ignition coil. Second terminals of output elements of photon- coupled pairs are connected, respectively, to central terminals spark plugs. Invention provides distribution of high voltage pulse by means of semiconductor devices whose reliability and service life exceed considerably those of electric voltage distributors. EFFECT: improved reliability, simplified design. 1 dwg
