Results of experimental studies of cold running-in of a diesel engine D-240 with increased load-rate modes

Abstract

Currently used diesel engine running-in methods are based mainly on typical technologies with the use of serial running-in and braking stands, which have limited speed and capacity for cold and hot running-in at idle and under load of all types of modern diesel engines, available in agricultural enterprises. In addition, typical running-in technologies have a number of technological, economic and environmental drawbacks. Taking into account high cost of up-to-date running-in equipment and low level of equipment of enterprises with serial running-in equipment, including those with long service life, the modernization of existing equipment is the urgent task, as well as the development of new technologies and means for their realization. The technology of cold running-in of diesels with increased load-rate modes using modernized running-in-brake stands and the developed system for increasing gas loads is proposed. The results of experimental studies show the possibility of creating higher load-rate modes during cold running-in of diesels and allow improving the typical technologies of running-in of diesels and means for their implementation.
