活塞環 (Piston Rings) 活塞環是發動機的關鍵部件，位於活塞與氣缸壁之間，主要負責密封燃氣、防止潤滑油洩漏、以及幫助散熱。根據應用需求，活塞環通常由鋼、鑄鐵或合金製成，以確保發動機的效率與耐久性。

 

      Piston Rings Piston rings are critical components of engines, positioned between the piston and the cylinder wall. Their primary functions include sealing combustion gases, preventing oil leakage, and aiding heat dissipation. Depending on the application, they are typically made from steel, cast iron, or alloy materials to ensure engine efficiency and durability.
