12、Automotive engine camshaftBrief introductionThe camshaft is a part of the piston engine. Its role is to control the opening and closing operation of the valve. Although the camshaft rotational speed in a four-stroke engine is a half of the crankshaft (the same as the camshaft rotational speed in a two-stroke engine with the crankshaft), but usually it is still very high speed, but also need to withstand the large torque, so the design right demanding camshaft in terms of strength and support mat。

13、汽车发动机如何工作在这里，我们将讨论的是一个发动机的基本理念，然后进入详细了解如何将所有部件结合在一起，以及如何提高性能！内部燃烧目前几乎所有的汽车使用的是所谓的四冲程燃烧循环转换成汽油的方案。这种四冲程步骤，又被称为了奥托循环，由受人尊敬的尼古拉斯奥托在 1867 年发明的。他们分别是： 摄入冲程或吸吮冲程压缩冲程或挤压冲程燃烧冲程或重击冲程排气冲程或吹气冲程活塞通过连杆连接到曲柄轴。这是发动机通过运行周期产生的：1.活塞在顶部启动，进气阀开启时，活塞向下移动，使发动机吸收满一缸空气和汽油。这是摄入冲。

14、GBT 18297-2001前 言由于汽车排放控制标准相继发布，且限值日趋严格，电子控制的发动机及燃气发动机已在国内投产，从而对发动机性能试验方法提出了许多新的要求，故制定了本标准。在制定的过程中，吸收了 QCT 524-1999 即 JB 3743-84汽车发动机性能试验方法长期的使用经验，并参考了 ISO 1585-1992道路车辆发动机净功率试验、ISO 2534-1998道路车辆发动机总功率试验等。本标准系在全国汽车标准化委员会的安排下，由汽车发动机标准化分技术委员会组织起草工作的。本标准的附录 A、附录 B、附录 C 及附录 D 都是标准的附录；附录 E、附录 F。

15、国际汽车发动机买卖合同20 14 年 09 月 10 日德国通用汽车零件生产有限公司为卖方和中国上海大众有限公司为买方。双方同意买卖 W 型汽车发动机，其条款如下：合同货物：W 型汽车发动机产地：德国柏林工厂 数量：1500 台 商标 ATLAS VENUS合同价格：1200000 元（壹佰贰拾万元） 包装：每个发动机用木箱装运，泡沫（厚大于 2cm）要足以保护发动机的正常使用。 付款条件：签订合同后买方于个银行日内开出以卖方为受益人的，经确认的、不可撤销的、可分割、可转让的、不得分批装运的、无追索权的信用证。 装船：从卖方收到买方信用证日期算起。

16、研窭 中，该缺陷部位充当了其它周边部位的补缩冒口，最终导 致了缩孑L的现象，因此加快该缺陷部位的凝固时间成为对 策的突破口。 514具体对策 根据客户图纸上的要求内腔容积有要求，不能够改变 故放弃了对砂芯加厚的方案。只能考虑从外围着手改善。从 肉厚检测数据以及图纸上标注的尺寸要求可以看出该缺陷 部位的加工余量单边达到了2Smm，因此决定进行加工余量 消减的改善措施，将加工余量从单边25ram削减到15ram。 515对策后效果说明 采取了两种检测方法进行验证，一种是x光检查另 外一种是较为传统的着色检查。两种方法一共取样48件 制。
