DETERMINATIOM OF EFFECTIVE METHOD OF RUNNING-IN OF QUARRY PBX ENGINES

A comparative analysis of the parameters of the efficiency of the rolling-braking and non-brake methods of loading the engine of quarry PBX is carried out. It is established that after major repairs for the investigated model of the engine of a quarry motor transport, it is necessary to carry out its run-in by a formless loading method. After a non-brake run-in, the engine life increases compared to engines that have not been run-in or have been run-in only at idle.
