Why Does Engine Sludge Occur?

1 Answers
StAugust
07/30/25 1:47am
Engine sludge occurs due to the following reasons: Blow-by gases contain various unburned products, dust, and metal oxides that enter the crankcase and mix with engine oil. Through further oxidation and condensation, they form acidic insoluble substances in the lubricating oil, which then combine with other solids and moisture to eventually form sludge deposits throughout the engine. Methods for maintaining a car engine: 1. Regularly change engine oil and oil filter; 2. Use lubricating oil of appropriate quality grade; 3. Periodically clean the radiator; 4. Maintain the three filters; 5. Keep the crankcase ventilated; 6. Regularly clean the crankcase; 7. Periodically clean the fuel system.

The Electronic Stability Program (ESP) is a general term for systems or programs that enhance vehicle handling performance while effectively preventing loss of control when the car reaches its dynamic limits. The Electronic Stability Program can improve vehicle safety and handling, typically supporting the functions of ABS and ASR.

What causes the rattling noise on the right side of GAC Trumpchi GS4?

There are many potential causes for vehicle rattling noises, each requiring specific analysis. Relationship between noise and engine RPM: Noise occurs only at idle or low speeds. Possible causes include: excessive clearance between piston and cylinder wall; overly tight piston pin or connecting rod bearing assembly; excessive clearance between tappet and guide hole; worn camshaft lobe profile. Relationship between noise and load: Many engine noises are clearly related to load. During diagnosis, you can test by progressively removing cylinder loads, typically using single-cylinder or dual-cylinder misfire methods to isolate one or two cylinders, thereby identifying the relationship between noise and load.

Why can't my BMW Mini read songs from the USB drive?

It may be due to an incompatible USB drive format that the vehicle cannot read. Solution: The USB drive might be in NTFS format, while car audio systems typically support FAT32 format. You'll need to reformat the USB drive to FAT32. Choosing a car USB drive: The only difference between car USB drives and regular USB drives is their appearance. Car USB drives are designed to be compact for space efficiency, while regular USB drives often have key rings for portability and anti-loss purposes. Regular USB drives can certainly be used with car multimedia systems. In fact, any car multimedia system that can read car USB drives can also read regular USB drives.
