摘要
选择了燃烧噪声的研究方法,对二甲醚发动机噪声的影响因素进行了试验研究和分析,明确了降低噪声的有效途径。通过本文的试验研究,可将原498型柴油发动机的燃烧噪声降低4.2dB。
The influential factors of noise for dimethyl ether engine are studied and analyzed through experiments by using method of combustion noise and effective solutions for noise reduction are found out. The combustion noise of original 498 diesel engine can be reduced by 4-. 2 dBA through methods introduced in this paper.
