FIELD: engines and pumps.
SUBSTANCE: proposed invention can be used for generation of four-stroke ICE sync signal NOCYL for ICE with uneven number of cylinders C1, C1, C3 with the help of electronic control system 7. Said NOCYL signal allows identification of preset moment at engine cylinder thermodynamic cycle. Sync signal is determined proceeding from TDC signal that identifies the position of every cylinder and signal Cg, Bn indentifying kinematics of crankshaft at fuel every ignition. Note here that both signals are generated on the basis of crankshaft position transducer 22. Proposed method comprises the steps whereat engine is operated for preset time interval with fuel ignition at engine every revolution, characteristic signal Cg, Bn is calculated with check magnitude at first second revolutions, sync signal NOCYL is re-initiated if sync signal is misphased.
EFFECT: decreased emission of contaminants.
