FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to internal combustion engines with distributed injection of fuel. According to proposed method of determination of phase of working cycle of four-stroke internal combustion engine with distributed group injection of fuel including successive measuring angular velocity of crankshaft, for each duty of engine threshold difference Delta Omega thr is set between successive measurands of angular velocity. Test injection of reduced/increased amount of fuel into one of cylinders is carried out. Difference Delta Omega between following measured values of angular velocity Omega is determined. Difference Delta Omega is compared with preset value of threshold difference Delta Omega thr for current operating conditions of engine, and working stroke of said cylinder is found from equation Delta Omega >Delta Omega thr. ^ EFFECT: possibility of determination of working cycle phases in system at no (vanishing) signal from phase sensor. ^ 2 cl, 2 dwg |
