What are the causes of abnormal noise in the Hawtai Santa Fe engine?
1 Answers
Hawtai Santa Fe engine abnormal noise has the following reasons: 1. Most common abnormal noises in the engine depend on the engine's speed state. The noise only exists at idle or low-speed operation. 2. The relationship between abnormal noise and load. Many abnormal noises in the engine are clearly related to its load. During diagnosis, the method of gradually removing the load can be used for testing, usually by using single-cylinder or double-cylinder misfire to remove the load of one or two cylinders to identify the relationship between the noise and the load. 3. The relationship between abnormal noise and temperature. Noise occurs at low temperatures and reduces or even disappears as the temperature rises. This could be due to excessive clearance between the piston and cylinder wall; incorrect depth and width of the main bearing oil groove; or low oil pressure leading to poor lubrication. Noise occurs when the temperature rises and reduces or disappears when the temperature drops. 4. The relationship between abnormal noise and the engine's working cycle. Abnormal noise faults in the engine are often clearly related to the engine's working cycle, especially noises from the crankshaft connecting rod mechanism and valve train, which are related to the working cycle. 5. The relationship between abnormal noise and the engine's location. When abnormal noise occurs in the engine, it will inevitably produce a certain degree of vibration. The characteristics and location of the vibration can assist in diagnosing the cause of the abnormal noise.
