:cool: Engine Terms(發(fā)動機術(shù)語) TDC(top dead center) ― the position of the crank and piston when the piston is farther away from the crankshaft." r3 Q+ o0 |2 V% m TDC (上止點) - 當(dāng)活塞離曲軸最遠時,曲柄和活塞的位置。 BDC (bottom dead center) ― the position of the crank and piston when the piston is nearest to the crankshaft. BDC (下止點) - 當(dāng)活塞離曲軸最近時,曲柄和活塞的位置。5 L$ S- J/ n/ G0 X2 ]& r" l stroke ― the distance between BDC and TDC; stroke is controlled by the crankshaft. 行程 - 下止點和上止點之間的距離;行程由曲軸控制。6 l2 }! t5 c" z. @ G A! _6 N }7 k8 R bore ― the internal diameter of the cylinder. 缸徑 - 汽缸的內(nèi)徑。' M* Y* E+ h2 w0 Z swept volume ― the volume between TDC and BDC. 有效容積 - 上止點和下止點之間的體積。 engine capacity ― this is the swept volume of all the cylinders, e.g. a four-cylinder engine having a capacity of two liters (2000 cm3) has a cylinder swept volume of 500 cm3." l: b' d G7 l* b 發(fā)動機排量 - 這是全部汽缸的有效容積,例如一臺排量為兩公升(2000 cm3)的4個汽缸的發(fā)動機每一個汽缸的有效容積為500 cm3。 clearance volume ― the volume of the space above the piston when it is at TDC.2 }6 k1 G8 E' W' X+ q+ `! n 間隙容積 – 當(dāng)活塞位于上止點時,活塞頂上面的氣缸空間。 compression ratio = (swept vol + clearance vol)/(clearance vol)! f. ^, t6 [; K- \9 { 壓縮比 = ( 有效容積 + 間隙容積 ) / ( 間隙容積 )1 ~.
