Mechanical Powertrain Damage/zh-hant

機械動力總成是指使車輛運動的機械系統。這包括內燃機、傳動系統、蒸汽鍋爐等。碰撞可能會造成機械動力總成損壞，也可能由不當操作車輛導致。缺乏潤滑，或較易發生的傳動系統過熱，將可能造成嚴重損害，甚至徹底失效，使車輛無法移動，或進而導致車身損壞。

Damage to such a powertrain subsystem can occur from collisions, but it is much more severe when caused by running powertrains at too high of a temperature , bad gear shifting and inadequate lubrication in diesel and steam engines. Exposure to fire , or submersion in water can also damage this subsystem.

High mechanical powertrain damage can be catastrophic, potentially fully immobilizing the vehicle.

柴油引擎的損耗速度也會隨著引擎的轉速變化。傳動系統部件的損耗取決於它們所承受的負載。雖然無法完全避免損壞，但透過輕柔地進行操作將可以將損耗降至最低。
