車身損壞。如銹蝕，凹陷，變形，脫焊，破裂等。銹蝕是由于漆膜損壞后，空氣中的潮濕氣及其它污染物引起的化學(xué)反應(yīng)所致。車身凹陷、變形 、脫焊、破裂等是由機(jī)械損傷所致。
Body damage. Such as rust, depression, deformation, desoldering, cracking, etc. Rust is caused by chemical reactions caused by moisture and other pollutants in the air after the paint film is damaged. The depression, deformation, detachment, and rupture of the vehicle body are caused by mechanical damage.
發(fā)動機(jī)不能啟動或啟動困難。出現(xiàn)這種情況多數(shù)都與主噴油器、冷起動噴油器、溫控開關(guān)、ECU和控制電路工作不良，蓄電池虧電，點火器或脈沖發(fā)生器損壞等因素有關(guān)。
The engine cannot start or is difficult to start. This situation is mostly related to factors such as poor operation of the main fuel injector, cold start fuel injector, temperature control switch, ECU and control circuit, battery depletion, and damage to the igniter or pulse generator.
離合器打滑。在離合器踏板完全放松時，汽車起步或重載上坡乏力，汽車加速時車速不能隨之提高，嚴(yán)重時離合器處出現(xiàn)冒煙和燒焦味。其實質(zhì)是摩擦力不足，主要由于離合器壓緊力降低或摩擦系數(shù)降低所致。
The clutch is slipping. When the clutch pedal is completely relaxed, the car may start or experience fatigue when overloaded uphill, and the speed cannot increase with acceleration. In severe cases, smoke and a burnt smell may appear at the clutch. Its essence is insufficient friction, mainly due to a decrease in clutch clamping force or a decrease in friction coefficient.
手動變速器跳檔。跳檔多發(fā)生在中、高速負(fù)荷突變或車輛顛簸時。主要是運動件過度磨損或變形失效，造成嚙合不正確，自鎖失控，檔位不能固定，發(fā)生跳檔。
Manual transmission jumps gears. Jumping gears often occurs when there is a sudden change in load at medium or high speeds, or when the vehicle is bumpy. Mainly due to excessive wear or deformation failure of moving parts, resulting in incorrect meshing, self-locking loss of control, inability to fix gear, and gear skipping.
行駛中使用制動，汽車不能減速或停車。原因可能是制動管路漏油或，漏氣，管路接頭破裂或脫落，制動密封元件失效等。
When using brakes while driving, the car cannot slow down or stop. The reason may be oil or gas leakage in the brake pipeline, rupture or detachment of pipeline joints, failure of brake sealing components, etc.
輪胎異常磨損。可能是由于氣壓不足或過高，前束或車輪外傾角過大或過小，車輪不平衡，輪胎長期未換位或球頭銷過度磨損，使用駕駛不當(dāng)?shù)确矫鎸?dǎo)致。
Abnormal tire wear. It may be caused by insufficient or excessive air pressure, excessive or insufficient toe or wheel camber, unbalanced wheels, long-term lack of tire rotation or excessive wear of ball joint pins, improper use and driving, etc.
