The invention discloses a diesel engine real machine test platform and method for cylinder sleeve-piston ring comprehensive performance analysis. The test platform comprises an experiment table base,a diesel engine body, a load simulation system, a measurement and control system and a computer data analysis system. A diesel engine output belt wheel is connected with the load simulation system through belt drive. Various sensors in the measurement and control system are arranged at key nodes of the diesel engine respectively, and signals obtained by the sensors pass through an analog-to-digital conversion module and a data acquisition card and enter the computer system for data analysis. The test platform can test and analyze the performance of the cylinder sleeve and the piston ring and the influence of the performance on the comprehensive performance of the diesel engine under a fuel load working condition, and can be widely applied to analysis and research of the comprehensive performance of the cylinder sl
