Method of diagnosing the technical condition of the cylinder-piston group of an internal combustion engine, which consists in preparing the engine for testing, installing primary converters on it: an electronic current converter and a signal synchronization sensor, which are connected to a measuring device, then the crankshaft is rotated by a starter, recording with subsequent playback of the current oscillogram at the battery terminal, determining the peak current at the moment of maximum pressure at the end of the compression stroke in each cylinder, while when the crankshaft is rotated by a starter, oscillograms are recorded in 2 modes: with the spark plugs installed and removed, the maximum current consumed by the starter at the end of the compression stroke in each cylinder is determined by the difference in currents of the first and second modes, and a conclusion is drawn about the technical condition of the cylinder-piston group of the engine as a whole.
