As the "heart" of a car, once there is a problem with the engine, the performance and safety of the vehicle will be seriously affected. So, how to determine if the engine is damaged? You can observe from the following aspects.
1. Abnormal sound: The sound is stable and regular when the engine is running normally. If there is a knocking sound, piercing metal friction sound, or whistling like abnormal noise, it may be due to wear, looseness, or poor lubrication of internal parts, and it needs to be repaired in a timely manner.
2. Decreased power: Feeling weak acceleration, difficult climbing, and even engine shaking while driving may be caused by ignition system malfunction, abnormal fuel injection, or insufficient cylinder pressure.
3. Abnormal exhaust: The color and odor of exhaust can reflect the condition of the engine. Black smoke may be due to insufficient fuel combustion; Blue smoke usually indicates burning of engine oil; Continuous white smoke accompanied by a decrease in coolant may indicate damage to the cylinder gasket or a ruptured cylinder block.
4. Fault light on: When the engine fault light on the vehicle dashboard lights up, it means that the vehicle's electronic control system has detected an abnormality. At this time, a diagnostic tool should be used as soon as possible to read the fault code and identify the problem.
5. Fuel consumption surge: When driving habits and road conditions remain unchanged, a sudden significant increase in fuel consumption may be due to a decrease in engine combustion efficiency, posing a potential risk of malfunction.
If the above symptoms are found in the vehicle, it is recommended to promptly send the vehicle to a professional repair shop for a comprehensive inspection to avoid small problems turning into major failures and causing greater losses.
