INTERNAL COMBUSTION ENGINE KNOCKING ELIMINATION METHOD Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to method of elimination of knocking in internal combustion engine operating at dynamic conditions. According to proposed method, use is made of data acquisition and preliminary processing device, control unit, knocking detector and dynamic conditions detector. Using data acquisition and preliminary processing device working parameters of internal combustion engine are determined. Using dynamic conditions detector transition of internal combustion engine to dynamic conditions is revealed. Using control unit, ignition advance angle is calculated depending on measured working parameters with due account of lead of load dynamic change under dynamic conditions, load dynamic change load is chosen from multiparameter characteristic stored in memory of control unit. Lead value from multiparameter characteristics is corrected in each case at moment of end of dynamic conditions of engine operation in compliance with intensity of knocking revealed by knocking detector.

EFFECT: effective elimination of knocking at dynamic conditions of operation of internal combustion engine.
