Mathematical Model of Estimation of the Quality of the Application of the Cylinder-piston Group of Thermal Diesels on the Criteria for the Stabilization of Fuel Consumption at the Real Time of Factory Tube Tests

Abstract

In the article, a mathematical model of the evaluation of the quality of running-in of a cylinder-piston group (GPG) based on the criterion for stabilizing fuel consumption in real time for running tests of diesel locomotives on the diesel locomotive frame is considered. The effect on the magnitude of fuel consumption of suddenness is shown to be the inclusion of the disconnection of auxiliary equipment connected to the engine crankshaft via a V-belt transmis-sion and a reducer with a compressor and water and air cooling fans. It was noted that the mathematical modeling of the on-off suddenness, carried out on the basis of the law of normal distribution, did not reveal a significant effect on the criterion of fuel consumption stabiliza-tion, with the help of which the quality of run-in was measured.
