Analysis and Research on the Power Enhancement Performance of a Marine High-power Diesel Engine

With the continuous development of the domestic shipbuilding industry,ships put forward higher requirements for diesel engine power.In order to adapt to social changes and meet the market demand,it is imperative to develop higher power diesel engines.In this paper,the AVL-BOOST software is used to establish the diesel engine working model for simulation,to build a diesel engine performance simulation model,to evaluate the feasibility of the diesel engine power rate improvement performance.From the aspects of cam profile and cylinder diameter,the diesel engine is optimized and simulated,and the optimal configuration of the diesel engine is matched.It provides a guiding direction for the development of diesel engine power improvement,and provides a technical basis for the transition stage of development from concept to design.
