CAUSES AND METHODS OF AVOIDING PREMATURE DAMAGE TO THE COOLING SURFACES OF DIESEL ENGINE CYLINDER LINERS

The paper reports on an investigation into why damage can occur on only one side of the liner, while on the opposite side of the liner damage is either insignificant or completely absent. The tests were made to determine experimentally the acceleration field of the liner, considered as the reaction of its surface to impact of a wave of gases and to impact of the piston, using the method of quantitative evaluation of the vibrational state of the engine. Measurements on an engine were made by the contact method and with an oscillograph, of the level of vibrational accelerations of the liner of the sixth cylinder at 12 points on its surface. An oscillograph was used to record accelerations at individual points and with sensors fitted simultaneously at three points with various combinations of their location on the liner surface. The severity of the reaction of the liner was evaluated from the amplitude and band-width of its accelerations.
