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、汽車發(fā)動機如何工作在這里，我們將討論的是一個發(fā)動機的基本理念，然后進入詳細了解如何將所有部件結(jié)合在一起，以及如何提高性能！內(nèi)部燃燒目前幾乎所有的汽車使用的是所謂的四沖程燃燒循環(huán)轉(zhuǎn)換成汽油的方案。這種四沖程步驟，又被稱為了奧托循環(huán)，由受人尊敬的尼古拉斯奧托在 1867 年發(fā)明的。他們分別是： 攝入沖程或吸吮沖程壓縮沖程或擠壓沖程燃燒沖程或重擊沖程排氣沖程或吹氣沖程活塞通過連桿連接到曲柄軸。這是發(fā)動機通過運行周期產(chǎn)生的：1.活塞在頂部啟動，進氣閥開啟時，活塞向下移動，使發(fā)動機吸收滿一缸空氣和汽油。這是攝入沖。

14、GBT 18297-2001前 言由于汽車排放控制標準相繼發(fā)布，且限值日趨嚴格，電子控制的發(fā)動機及燃氣發(fā)動機已在國內(nèi)投產(chǎn)，從而對發(fā)動機性能試驗方法提出了許多新的要求，故制定了本標準。在制定的過程中，吸收了 QCT 524-1999 即 JB 3743-84汽車發(fā)動機性能試驗方法長期的使用經(jīng)驗，并參考了 ISO 1585-1992道路車輛發(fā)動機凈功率試驗、ISO 2534-1998道路車輛發(fā)動機總功率試驗等。本標準系在全國汽車標準化委員會的安排下，由汽車發(fā)動機標準化分技術(shù)委員會組織起草工作的。本標準的附錄 A、附錄 B、附錄 C 及附錄 D 都是標準的附錄；附錄 E、附錄 F。

15、國際汽車發(fā)動機買賣合同20 14 年 09 月 10 日德國通用汽車零件生產(chǎn)有限公司為賣方和中國上海大眾有限公司為買方。雙方同意買賣 W 型汽車發(fā)動機，其條款如下：合同貨物：W 型汽車發(fā)動機產(chǎn)地：德國柏林工廠 數(shù)量：1500 臺 商標 ATLAS VENUS合同價格：1200000 元（壹佰貳拾萬元） 包裝：每個發(fā)動機用木箱裝運，泡沫（厚大于 2cm）要足以保護發(fā)動機的正常使用。 付款條件：簽訂合同后買方于個銀行日內(nèi)開出以賣方為受益人的，經(jīng)確認的、不可撤銷的、可分割、可轉(zhuǎn)讓的、不得分批裝運的、無追索權(quán)的信用證。 裝船：從賣方收到買方信用證日期算起。

16、研窶 中，該缺陷部位充當了其它周邊部位的補縮冒口，最終導 致了縮孑L的現(xiàn)象，因此加快該缺陷部位的凝固時間成為對 策的突破口。 514具體對策 根據(jù)客戶圖紙上的要求內(nèi)腔容積有要求，不能夠改變 故放棄了對砂芯加厚的方案。只能考慮從外圍著手改善。從 肉厚檢測數(shù)據(jù)以及圖紙上標注的尺寸要求可以看出該缺陷 部位的加工余量單邊達到了2Smm，因此決定進行加工余量 消減的改善措施，將加工余量從單邊25ram削減到15ram。 515對策后效果說明 采取了兩種檢測方法進行驗證，一種是x光檢查另 外一種是較為傳統(tǒng)的著色檢查。兩種方法一共取樣48件 制。
