In the process of using the construction machinery, it is often affected by the fluctuating load which directly affects the normal performance of the engine. In order to adapt the performance of the diesel engine to the dynamic load condition of the construction machinery, it is necessary to dynamically load the engine in the interior Experimental study in order to master the law of dynamic changes in engine performance under dynamic loading conditions, so as to improve the dynamic performance of the engine to provide a scientific basis for this article through the 61 35 -K1 3 diesel engine simulation loading test, the use of static and dynamic characteristics of contrast The influence of periodic load and step load excitation on the dynamic process and performance of diesel engine with variable speed were analyzed. The reasons for the deterioration of diesel engine performance compared with static performance index under dynamic load were described. In order to further improve the performance of diesel engine, The performance of a mechanical governor diesel engine provides important test data
