Research on Experimental loss and Lubrication Correction parameters of Internal Combustion engine equipment

In terms of nature, the internal combustion engine is a kind of power machinery. Through the analysis of the maintenance operation flow of diesel locomotives and combined with the control principle of diesel locomotives, the key cost waste points in the experimental process of diesel locomotives are determined and optimize the experimental process and reduce the cost waste in the maintenance process. Based on the cam-roller mechanism of an internal combustion engine, the corresponding numerical model of elastohydrodynamic lubrication of the contact pair is established, and the complete lubrication state of the motion pair in the cam rotation cycle is obtained. The effects of roller crown, lubricating oil viscosity and skidding between cam and roller are analyzed. The results show that the lubrication state of the cam-roller contact pair can be divided into the fluctuation period and the stationary period, which corresponds to the changing law of the cam lift. The slipping phenomenon between cam and roller will reduce the film thickness in the contact zone, especially on the temperature rise and friction coefficient of lubricating oil.
