How to Solve the Engine Noise Issue in Baojun 510?
4 Answers
Here are specific methods to eliminate engine noise in Baojun 510: 1. Reduce compressor stage load, increase axial clearance between rotor and stator, change blade count, remove inlet guide vanes, and select appropriate compressor speed to lower compressor noise. 2. Decrease exhaust velocity to reduce jet noise, such as increasing bypass ratio in turbofan engines to lower exhaust speed. 3. Use corrugated and lobed nozzles to increase contact area between jet flow and external airflow, thereby reducing jet mixing noise. 4. Apply sound-absorbing liner structures on engine pipe walls. In aero-engine noise research, noise can be viewed as composed of monopole, dipole, and quadrupole noise sources. Monopole noise, caused by mass fluctuations and structural vibrations, commonly occurs in engine intakes and exhaust nozzles, predominantly at low frequencies.
After driving my Baojun 510 for a long time, the engine started making a humming sound, which my experience as a car-loving veteran driver helped me notice. Possible causes include a loose or worn belt—first, check the belt for cracks and try tightening it yourself if possible. Low engine oil is also a common issue; check the dipstick and top it up with fresh oil if it's low. Bearing problems could be another culprit, especially if there's a squeaking sound when turning—this usually requires a reliable repair shop if you can't handle it yourself. Too much carbon buildup can also cause trouble, so always use reputable fuel to prevent the engine from ingesting impurities. Don't ignore minor noises—delaying repairs can damage the car and cost more in the long run. Safety comes first; address the issue early for peace of mind on the road.
I always enjoy fixing my own car to save money and gain knowledge. Last year when my Baojun 510 had loud engine noise, I first checked if the belt was aged or broken. If it was slightly loose, I could tighten it with tools. Dirty engine oil is also a common issue, so I tried changing to fresh oil. If the noise sounded like grinding stones, it might be a bearing failure requiring part replacement. But for complex issues like valve problems, after learning to identify them, I also recommend taking it to a professional shop for inspection—no point in unnecessary tinkering that saves no money and causes trouble. Regular maintenance like changing filters and cleaning carbon deposits reduces noise and extends the car's lifespan.
As a newbie who recently bought a Baojun 510, I'm quite troubled by the noise issues. Experienced drivers told me it might be due to low engine oil—just check the dipstick and top it up if needed. Excessive carbon buildup can also cause strange noises, and cleaning the engine should fix it. Or it could be a sensor malfunction; avoid disassembling it yourself to prevent damage. Whenever I notice a humming sound, I take it to the 4S shop—they diagnose and fix the problem quickly. New drivers should never ignore these issues; addressing the noise promptly ensures the car remains safe.
