举一反三
- At the bottom dead center (BDC), the piston moves back up, compressing the trapped fuel-air mixture in the cylinder with both intake and exhaust valves closed．
- The scavenging air ports are located at （） that they are just exposed by the upper edge of the piston when the piston is in the bottom dead center position.
- The small end of the connecting rod is attached to the piston with a （）.
- Aboard a ship，multiplying a load’s weight by the distance of the load’s center of gravity from the centerline results in the load’s（）.
- Which term describes piston pins having bearing surfaces in both the piston bosses and connecting rod eye?（）
