FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to ignition timing control systems. It is aimed at optimization of process of conversion of energy of combusted fuel-air mixture into mechanical energy of engine crankshaft rotation. Proposed invention makes it possible to determine automatically and time optimum ignition moment of fuel-air mixture in any internal combustion engine irrespective of its condition, grade of fuel and environment. According to invention, commencement of moment of ignition of fuel-air mixture is regulated by results of end of burning. Burning process of fuel-air mixture is monitored by light-sensitive flame pickup, and after each cycle actual and preset time of burning of entire amount of fuel-air mixture is compared. Basing of obtained data, ignition timing for following cycle is corrected.
EFFECT: increased efficiency of internal combustion engine.
