What Sound Does Cylinder Scoring Make?
2 Answers
When an engine experiences cylinder scoring, a "click, click, click" sound can be heard during idle operation. This is the noise produced during the early stages of mild cylinder scoring. As the temperature rises, the sound becomes duller and is accompanied by engine vibration. It's important to note that determining whether an engine has cylinder scoring cannot be based solely on the sound it makes. Below is an introduction to engine cylinder scoring: 1. Cylinder scoring is one of the common faults in car engines. Engine cylinder scoring refers to deep grooves being formed on the inner wall of the cylinder, causing the piston, piston rings, and cylinder wall to lose their sealing ability during friction. This results in reduced cylinder compression pressure and loss of power. 2. The causes of cylinder scoring are highly complex and involve many factors, such as material selection, determination of clearance size, appropriateness of installation alignment, rationality of structural arrangement, suitability of surface roughness, and adequacy of lubrication and cooling arrangements.
I used to drive an old truck, and when it had cylinder scoring issues, the sound was particularly horrifying. It made a continuous 'clattering' noise, like someone was hammering on a metal box, especially louder when climbing hills or accelerating. Every time I pressed the gas pedal, the sound became more rapid, accompanied by engine shaking and loss of power. That experience cost me nearly ten thousand yuan to repair, and the mechanic said the cylinder walls and piston rings were severely worn, causing compressed gas leakage which led to this noise. Now, whenever I hear a similar abnormal sound, I immediately check the engine oil and cooling system, because ignoring such a small sound could potentially ruin the entire engine. I suggest everyone take good care of their cars with regular maintenance.
