TDC(top dead center) ― the position of the crank and piston when the piston is farther away from the crankshaft.
; }) V% e& ~& K. x4 t7 f( }; h0 N TDC (上止點) - 當活塞離曲軸最遠時,曲柄和活塞的位置。0 D; q6 S1 v( T7 }1 k
BDC (bottom dead center) ― the position of the crank and piston when the piston is nearest to the crankshaft.

行程 - 下止點和上止點之間的距離;行程由曲軸控制。5 g5 G$ c# P- l% y
bore ― the internal diameter of the cylinder.

swept volume ― the volume between TDC and BDC.3 u4 n1 o8 \: j) \ e5 A
有效容積 - 上止點和下止點之間的體積。7 G0 ~$ w$ Q5 L# \& k
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)

clearance volume ― the volume of the space above the piston when it is at TDC.
# k9 l% t/ I7 x 間隙容積 – 當活塞位于上止點時,活塞頂上面的氣缸空間。
