TDC(top dead center) ― the position of the crank and piston when the piston is farther away from the crankshaft.
1 N# r) @: i) A) W! F, g" a TDC (上止点) - 当活塞离曲轴最远时，曲柄和活塞的位置。
9 y9 Y- P0 N9 e6 R/ [: K/ Y BDC (bottom dead center) ― the position of the crank and piston when the piston is nearest to the crankshaft.
' r3 c6 Y. F0 Q3 I9 n: ] BDC (下止点) - 当活塞离曲轴最近时，曲柄和活塞的位置。0 ^5 p$ o- ]2 z8 [" r$ C7 S
stroke ― the distance between BDC and TDC; stroke is controlled by the crankshaft.& s1 G2 X) z% Q+ u$ g
行程 - 下止点和上止点之间的距离；行程由曲轴控制。

swept volume ― the volume between TDC and BDC.; n! [& i1 A: w- `$ K/ A9 Q
有效容积 - 上止点和下止点之间的体积。

发动机排量 - 这是全部汽缸的有效容积，例如一台排量为两公升(2000 cm3)的4个汽缸的发动机每一个汽缸的有效容积为500 cm3。
9 ^& c; j: @/ N) Z clearance volume ― the volume of the space above the piston when it is at TDC.+ r7 s3 \7 c2 [
间隙容积 – 当活塞位于上止点时，活塞顶上面的气缸空间。
! h m, D/ j4 E0 H compression ratio = (swept vol + clearance vol)/(clearance vol)
$ @' I. R( \1 ~" f' u 压缩比 = ( 有效容积 + 间隙容积 ) / ( 间隙容积 )/ X7 y6 k& E W( @! D
two-stroke ― a power stroke every revolution of the crank.

four-stroke ― a power stroke every other revolution of the crank.
