Analysis for Combustion Process in Cylinder of 5S60 Diesel Engine

摘要

The optimization and matching question for the low-speed diesel engine's combustion process determines its power,efficiency and emission.But the optimization and matching of the combustion process is related with the fuel injection rule,the intake swirl control,the valve timing adjustment,the combustion chamber structure,the operating condition parameter and so on.This paper takes the 5S60 marine low-speed diesel engine as the study object.The whole running phase-oriented model based on the unified multi-domain has established,and the analysis for the diesel engine's combustion process in cylinder has carried on.The analysis result provides the technical support for the economical,safe and reliable operation of the diesel engine.Thus the combustion process in cylinder is improved,the diesel engine's performance is enhanced,and the pollutant discharge is reduced.
