標題:Opposed-Engine crankcase

The crankcase for a four-cylinder opposed engine is shown in fig2-1.this assembly consists of two matching,rein-forced aluminum-alloy castinds dividwd vertically at the centerline of the engine and fastened together by means of a series of studs and nuts.the mating surfaces of the crankcase are joined without the use of a gasket, and the main-bearing bores are machined for the use of precision-typ main-bearing inserts.

Machined mounting pads are incorporated into the crankcase for attaching the accessory housing,cylinders,and oil sump,as shown in Fig.2-2.Opposed engines with propeller reduction gearing usually incorporate a separate nose section to house the gears.

The crankcase of the opposed endine contains bosses andmachined bores to serve as bearings for the camshaft.On the camshaft side of each crankcase half are the tappet bors which carry the hydraulic valve tappet bodies.

Essential portions of the lubricating system are con-tained in the crankcase.Oil passages and galleries arre drilled in the sections of the case to supply the crankshaft bearings, camshaft bearings,and various other moving parts which require lubrication. During overhaul, the tech-nician must make sure that all oil passages are free of for-eign matter and that passages are not blocked by gaskets during assembly.

就這些英文請幫忙翻譯..我需要全部的翻譯還有每句的分開的翻譯還有..遇到專業名詞時請用(航太)專業的英文名詞,且要翻譯的非常流暢要非常精確,謝謝.p.s標題的英文也要翻譯喔!!

    Opposed-Engine crankcase

    The crankcase for a four-cylinder opposed engine is shown in fig2-1.this assembly consists of two matching, rein-forced aluminum-alloy castinds (casting) dividwd (divided) vertically at the centerline of the engine and fastened together by means of a series of studs and nuts. The mating surfaces of the crankcase are joined without the use of a gasket, and the main-bearing bores are machined for the use of precision-type main-bearing inserts.

    Machined mounting pads are incorporated into the crankcase for attaching the accessory housing, cylinders and oil sump(bump),as shown in Fig.2-2.Opposed engines with propeller reduction gearing usually incorporate a separate nose section to house the gears.

    反向引擎的曲柄蓋

    四衝程對向引擎的曲柄蓋,如圖2-1。本組件由2 個相配合 的強化鋁合金鑄件構成。由引擎的中心線垂直分開為上下,並由一連串螺栓螺帽鎖緊,接合面無需軟襯。而且主要培林孔需加工來裝配高精密培林。架設墊是由 (曲柄蓋一體???)加工而成,用以架設組件如 外蓋,汔缸,油汞 如圖2-2。反向引擎具有螺旋槳減速齒輪系統通常會配接一個鼻端作為齒輪的外蓋。

    The crankcase of the opposed engine contains bosses and machined bores to serve as bearings for the camshaft. On the camshaft side of each crankcase half are the tappet bors (是bore 還是 boss) which carry the hydraulic valve tappet bodies.

    曲柄蓋包含圓柱及加工孔作為偏心軸的軸承。在每片曲柄蓋的偏心軸那一端為凸輪推桿的圓柱(boss),用以裝設 (carry) 油壓閥瓣的凸輪推桿 (tappet)本體。

    Essential portions of the lubricating system are con-tained in the crankcase.Oil passages and galleries arre drilled in the sections of the case to supply the crankshaft bearings, camshaft bearings,and various other moving parts which require lubrication. During overhaul, the tech-nician must make sure that all oil passages are free of foreign matter and that passages are not blocked by gaskets during assembly.

    潤滑系統的基本元件包含在曲柄蓋內。油路與集油槽是從曲柄蓋上鑽出用以供給曲柄軸培林,偏心軸的培林及其它的轉動件的潤滑用油。在大修時,機工需注意有無異物,以及油路在組裝時被軟襯阻塞。

    譯註:除opposed engine 以外,都是機械常見用語。

    我猜 opposed engine 為螺旋槳在飛機後的引擎吧!我猜的對不對可從附圖看出,只要是出力端的arbor是朝向機尾。我把它翻成反向引擎,應該是雖不中、不遠矣。

    incooperate into 這一詞我們常解釋為 成為一體,或接合成一體。兩者意思不太一樣。
