气缸盖罩

根据气缸盖罩的结构和使用要求，进行板件成型工艺分析与结构设计，同时利用CAD技术进行模具模芯的设计，并利用CAM技术进行模具形腔的加工。

Based on the structure and usage of the cylinder head cover , the technical analysis and the struc - tural design of plate-shaping are conducted in this article . Meanwhile , the mould core is designed and the mould shape is machined by utilizing CAD technology .

为了降低柴油机气缸盖罩的成本，使用板件替代原先的铸铝件。

In order to reduce the cost of the diesel engine cylinder head cover , the panel substituted the original aluminum cast part .

研究结果表明：油底壳、皮带轮、进气、气缸盖罩为主要噪声源，复合钢板油底壳有良好的降噪效果，并提出了进一步降低该发动机噪声的改进措施。

This research shows that the oil pan , pulley , intake and cylinder head cover are the main noise resources , and using sandwich steel plate oil pan makes the good noise reduction result . More methods of reducing noise of this engine were devised .
