Simulation Study on the Overall Performance Optimization for 4190 Series Marine Diesel Engine Based on AVL BOOST Software
The middle speed 4-stroke diesel engines has the advantages of small capacity, light in weight, capable to combustion poor fuel oil. In recent years, they have been used more comprehensive than before. The simulation model of 4190ZLC 4-stroke marine diesel engine is established by using AVL BOOST software and the laboratory platform experiment is completed under rated operating conditions. The accuracy of the model is verified by comparing the simulation and experimental results. The compression ratio, the starting angle of combustion and the valve timing on diesel engine performance are discussed by BOOST model established, and in order to carry out the optimization calculation of the diesel engine, the output power of the diesel engine as a target, cylinder peak pressure as a constraint condition, and fuel consumption rate as the optimization object. The results show that the optimized diesel engine performance improved to some extent. On the basis of the numerical calculation for 4190ZLC medium-speed turbocharged diesel engine, these results will provide some theoretical support to improve operational performance for heavy-duty 4-stroke marine diesel engine.
