Abstract
The reliability of locomotive diesel engines largely depends on a timely and objective assessment of the technical condition of its equipment during operation. The article proposes a technique for the integral assessment of the technical state of the quality of the working process in a diesel cylinder using on-board diagnostics.
Highlights
Improving the operational efficiency and reliability of diesel locomotives requires continuous monitoring of the technical condition of their equipment during operation
The problem of a reliable assessment of the quality of the working process in the cylinders of a diesel locomotive and the technical condition of the fuel equipment and the cylinder-piston group determining it is currently being solved by stationary and on-board diagnostic tools based on the analysis of the indicator diagram of the working process
The use of such an approach for continuous monitoring of the technical condition of a diesel locomotive in operation is impossible for several reasons, the main of which is the lack of technical capability to continuously measure the pressure in the diesel cylinder, which is necessary to remove the indicator diagram
Summary
Improving the operational efficiency and reliability of diesel locomotives requires continuous monitoring of the technical condition of their equipment during operation. The problem of a reliable assessment of the quality of the working process in the cylinders of a diesel locomotive and the technical condition of the fuel equipment and the cylinder-piston group determining it is currently being solved by stationary and on-board diagnostic tools based on the analysis of the indicator diagram of the working process The use of such an approach for continuous monitoring of the technical condition of a diesel locomotive in operation is impossible for several reasons, the main of which is the lack of technical capability to continuously measure the pressure in the diesel cylinder, which is necessary to remove the indicator diagram. This can be used as a diagnostic sign of deterioration of the technical condition of the cylinder and serve as the basis for setting it for stationary diagnostic control [1, 9]
