摘要

针对船用柴油机工作不均匀及循环波动对柴油机性能和振动噪声的负面影响问题，以6L16/24-CR型船用中速柴油机为对象，使用软件在环仿真技术对缸压闭环控制策略进行仿真分析。建立能模拟各缸不均匀性和循环波动的柴油机实时模型，从气缸压力中选取能指示柴油机各缸燃烧状态的反馈变量，根据反馈变量和控制变量之间的动态关系开发缸压闭环控制策略，建立由柴油机实时模型、气缸压力反馈变量、控制策略和喷油控制变量构成的软件在环仿真平台，在该软件在环仿真平台上对缸压闭环控制策略进行闭环仿真。结果表明，开发的缸压闭环控制策略能满足船用柴油机的控制要求，在仿真环境下能改善约99%的各缸不均匀。

Abstract

To eliminate the negative effects of cylinder-to-cylinder unevenness and cycle-to-cycle variation of marine diesel engine on engine performance

vibration and noise

taking a 6L16/24-CR type medium speed marine diesel engine as the research object

an in-cylinder pressure based closed-loop combustion control strategy was investigated with the software-in-loop simulation technology. First

an engine real-time model was established and verified

which was capable of simulating the inhomogeneity of all cylinders and cycle-to-cycle variation. The feedback variables that could indicate the combustion state of each cylinder were extracted from in-cylinder pressure

and a closed-loop combustion control strategy was developed based on the dynamic interaction between the combustion control variables and feedback variables. Next

a software-in-loop simulation platform was built on the base of the engine real-time model

feedback variables

combustion control strategy and fuel injection control variables. Finally

the simulation of the closed-loop combustion control strategy based on in-cylinder pressure was conducted on the platform. The results show that the developed closed loop combustion control strategy based on in-cylinder pressure can meet the combustion control requirements of marine engines

and about 99% of cylinder-to-cylinder unevenness is restrained in the simulation environment.
