機械動力總成損壞

機械動力車輛 ，即其動力總成 由柴油引擎 、蒸汽機 ，和機械 、液力 傳動系統等組成。

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 , inadequate lubrication in diesel and steam engines, and other mistreatments. 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。
