BDC
English: BDC
Chinese: 控制主要损伤
热稳性人造金刚石复合片
下死点
Examples:
1. "After the piston has passed through BDC and starts up again, it passes Both ports, thus sealing them off."
在活塞通过下止点,并开始上升时,活塞经过进气口和排气口,将其堵
2. "After the piston reaches BDC, or the lower limit of its travel, it begins to move upward. As this happens, the intake valve closes. The exhaust valve is also closed, so that the cylinder is sealed."
"在活塞到达下止点时,或者是活塞下限时,活塞开始向上运动。同时,进气门关闭,排气门也关闭,所以这时的气缸是封闭的。"
3. "As the piston nears BDC, it passes the intake and exhaust ports in the cylinder wall. Burned gases, still under some pressure, begin to stream out through the exhaust port."
当活塞接近下止点时,经过气缸壁上的进排气口,燃烧过的气体,仍有剩余压力,开始从排气口喷出。
4. "As the piston reaches BDC again, the exhaust valve opens. Now, as the piston moves up on the exhaust stroke, it forces the Burned gases out of the cylinder through the exhaust-valve port."
当活塞再一次到达下止点时,排气门打开。同时,活塞向上移动,把废气经排气门排出气缸。
5. "In the two-cycle engine, the piston acts as a valve, clearing valve ports in the cylinder wall as it nears BDC."
在二行程发动机中,活塞起到阀门的作用,当活塞接近下止点时,使气缸壁上的进排气口打开。
6. "Then, when the piston reaches TDC, the exhaust valve closes and the intake valve opens. Now, a fresh charge of air-fuel mixture will be drawn into the cylinder as the piston moves down again toward BDC."
随后活塞达到上止点,排气门关闭,进气门打开.当活塞又一次向下移动到达下止点时,新鲜可燃混合气被吸人气缸.
7. BDC (Binary Decimal Counter)
二-十进制计数器
8. BDC(Block Down Converter)
下变频器
9. The Bore is the diameter of the cylinder. The stroke is the distance the piston travels from BDC (Bottom dead center) to TDC(top dead center). The Bore is always mentioned first.
内径指的是气缸的直径;行程是活塞从下止点运行到上止点的距离。表述时,内径总是写在前面。
10. The upper limit of piston movement is called TDC (top dead center). The lower limit of piston movement is called BDC (Bottom dead center). A stroke is piston movement from TDC to BDC or from BDC to TDC.
"活塞运动的上限称为TDC(上止点),下限称为bdc(下止点).一个行程就是活塞从上止点到下止点,或下止点到上止点的运动."
