DEVICE TO CONTROL MOMENT OF IGNITION OF INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02P5/145 

FIELD: automotive industry; electrical equipment of automobiles.

SUBSTANCE: proposed ignition control device of internal combustion engine contains crankshaft position pickup and electronic ignition device containing comparator and controlled one-shot multivibrator. Device includes additionally first low-pass, filter, voltage stabilizer, variable resistor, second low-filter, optron. Crankshaft position pickup is connected with trigger input of controlled one-shot multivibrator and with input of first low-pass filter whose output is connected with first input of comparator. Plus wire of device is connected with input of stabilizer whose output s connected with first output of variable resistor whose second output is connected to frame and third output, with second input of comparator whose output, through second low-pass filter, is connected to input optron, photoresistor of which is placed in time-setting circuit of controlled one-shot multivibrator.

EFFECT: simplified design, reduced cost of device.
