ELECTRONIC SYSTEM FOR IGNITION SYNCHRONIZATION FOR INTERNAL COMBUSTION ENGINE AND METHOD OF ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: spark ignition. SUBSTANCE: electronic system for ignition synchronization for internal combustion engine includes sensor of position of teeth of engine gear that detects rotation of this gear and forms signal when every tooth of gear passes by mentioned sensor and sensor of phase of engine forming signal with every cycle of operation of engine. System also incorporates aid that multiplies signal of position of teeth of gear by integral number multiple of number of cylinders in engine and generates high- resolution signal of rotation of engine in the form of sequence of pulses. Each of them in this sequence indicates angular position of engine determined in advance. System has aid forming cycle reference signal per each cylinder of engine to ensure synchronization. Number of pulses of rotation signal of engine per each cycle of operation determined in advance is divided in accordance with signal of phase into equal synchronization intervals per each cylinder. Each synchronization interval is marked by reference marker of cycle of cylinders. System includes aid controlling synchronization of combustion process in corresponding cylinders of engine. EFFECT: provision for synchronization of controlling high-resolution signals of operation of engine. 18 cl, 3 dwg
