IGNITION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F02P5/04 F02P5/145 F02P15/00 F02P15/08 F02P15/12 

FIELD: engines and pumps.

SUBSTANCE: invention refers to the transport area and may be used in ignition systems. Within the ignition control system for an internal combustion engine, ECU gives a signal of ignition Si to an ignition device via a line of ignition data transmission. The ignition device performs an operation of closing of an ignition-switching component at a time interval, during which the signal of ignition Si is given. ECU gives a signal Sc of control of a discharge pulse form into a line of data transmission for control of a discharge pulse form at a moment of time, which is delayed by a preset delay interval with respect to a moment of an ignition signal Si injection. Within the time interval of an input of a signal Sc of control of a discharge pulse form after termination of an input ignition signal Si, the ignition device, with the help of an opening-closing operation of the ignition-switching component, sets an electric current running via the primary coil; this current is equal to a prescribed value of a discharge current set in dependence on the above-said delay interval.

EFFECT: ignition control system for an internal combustion engine allows reducing energy consumption simultaneously maintaining ignition parameters.
