METHOD OF AUTOMOTIVE ENGINE IGNITION Russian patent published in 2011 - IPC F02P5/00 

FIELD: engines and pumps.

SUBSTANCE: proposed method consists in registering piston reference point, measuring crankshaft cycle period, engine load, engine temperature, incoming air temperature and fuel jet opening period, determining advance angle and generating ignition pulse in ignition coil. In determining advance angle, its variation range is divided into some discrete magnitudes. Dependence of cylinder pressure on crankshaft angle is calculated proceeding from measurements made to determine maximum pressure crankshaft angle. Discrete magnitude whereat maximum cylinder pressure crankshaft angle approximates to 10° after TDC is taken to be required advance angle.

EFFECT: increased crankshaft torque.
