摘要
噪声水平优劣是柴油机品质的重要表现,对柴油机燃烧室结构、压缩比及电控燃油系统参数对噪声影响的研究,发现气缸压缩比和燃油系统轨压对噪声影响较大,在对燃烧系统各参数优化后达到降低整机噪声的目的。
The merits of engine noise is the important embodiment of high quality of engine .Discovered that the compression ratio of cylinder and pressure of common rail produced a great impact on engine noise through the study of the influence on the structure of combustion chamber, compression ratio and the system of electronic fuel system. After optimized the parameters of engine combustion system the engine noise reduced.
