Formation of engine support reactions during controlled change of compression value in cylinders

The effect of compression in cylinders on the change in the reactions of internal combustion engine supports in idle mode is investigated. It is established that the maximum effect of compression on the reactions of engine supports occurs at the minimum crankshaft rotation frequency. It is proposed to use the reaction of supports as a diagnostic parameter for the operational assessment of the technical condition of the cylinder-piston group of the engine.
