FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: according to proposed method of control of internal combustion engine, basing on first value characterizing amount of injected fuel and second value characterizing angular position in which metering out of fuel for injection is carried out, third value characterizing torque developed by internal combustion engine is found. Basing on fourth value characterizing control action set by driver, fifth value is found characterizing torque set by driver, and third and fifth values are subjected to processing and analyzing for revealing troubles. First value corresponds to duration of control action or signal to output stage, first of all, to electromagnetic valve or electromagnetic valve nozzle, or to piezoelectric drive. Second value corresponds to angular position of crankshaft at which injection takes place. Fourth value corresponds to position of member or element of control. Trouble is revealed if mismatching of third and fifth values exceeds preset threshold value. Trouble check should be carried out only under definite operating conditions. Control device of internal combustion engine makes it possible to implement the method. ^ EFFECT: possibility of reliable and accurate revealing of troubles in fuel metering system and/or recording of control action preset by driver. ^ 3 cl, 3 dwg |
