! i8 L$ r; F* p7 Y4 s TDC(top dead center) ― the position of the crank and piston when the piston is farther away from the crankshaft.1 b5 \7 k: M6 H$ L
TDC (上止点) - 当活塞离曲轴最远时,曲柄和活塞的位置。* i0 b# o" |8 G2 I
BDC (bottom dead center) ― the position of the crank and piston when the piston is nearest to the crankshaft.
. P# \! r" r* f5 W/ K BDC (下止点) - 当活塞离曲轴最近时,曲柄和活塞的位置。
# e) Q0 n+ Y- J7 Y stroke ― the distance between BDC and TDC; stroke is controlled by the crankshaft.
. @- n: f7 ~, B% w. b 行程 - 下止点和上止点之间的距离;行程由曲轴控制。

( X n# y3 ? O swept volume ― the volume between TDC and BDC.9 ?- c) J9 }8 ?9 q
有效容积 - 上止点和下止点之间的体积。
( y2 e. \1 E/ }8 r 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)
6 s$ s* E" c. N5 V has a cylinder swept volume of 500 cm3.$ J! d3 ^& w+ y7 I$ {
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。
( o, D5 T0 I; l& q6 x. F' ?8 e clearance volume ― the volume of the space above the piston when it is at TDC.) ?0 t* ~6 W% @, v a) H
间隙容积 – 当活塞位于上止点时,活塞顶上面的气缸空间。
! o/ U# h& Q0 [) j' X$ g; } compression ratio = (swept vol + clearance vol)/(clearance vol)
; N: V6 m: Q2 [! b& ]& N( Z, U 压缩比 = ( 有效容积 + 间隙容积 ) / ( 间隙容积 )
; R& s; `* J3 t3 @6 e two-stroke ― a power stroke every revolution of the crank.# ?& O3 p. R5 A: K, b" T# \0 s: F
二冲程 – 曲柄旋转一圈作功一次。9 i2 g* r. n2 f# h7 Q
four-stroke ― a power stroke every other revolution of the crank.
' p! X( Y, @2 t/ y 四冲程 - 曲柄旋转两圈作功一次。 |
