What are the consequences of not repairing engine knocking?
3 Answers
Engine knocking if left unrepaired can lead to: 1. Affecting the normal operation of the engine; 2. Causing a decrease in the vehicle's power; 3. Generating a large amount of carbon deposits during engine operation, resulting in increased fuel consumption. Knocking refers to the phenomenon where certain carbon deposits are produced during engine operation. Excessive carbon deposits in the combustion chamber can increase the engine's compression ratio, leading to excessively high gas pressure and temperature, which causes detonation of the fuel in the combustion chamber. An engine is a machine capable of converting other forms of energy into mechanical energy. It can refer to both the power generation device and the entire machine including the power unit, such as gasoline engines, aircraft engines. Types include internal combustion engines, external combustion engines, electric motors, etc.
The knocking sound was like drumming. I encountered it when driving an old car and didn't fix it in time, which made it louder and louder. Later, the engine vibrated violently, the power dropped, and the fuel consumption soared, almost causing a breakdown on the road. During inspection, scratches were found on the cylinder wall, and the piston was worn out. The repair cost 5,000 yuan, ten times more expensive than fixing a minor issue. If I had continued to delay, it might have led to cylinder scoring and engine failure, with a replacement costing over 10,000 yuan. The car also became unstable, with the steering feeling loose at high speeds, posing a major safety hazard. Daily driving became nerve-wracking. I suggest everyone get any unusual noises checked by a professional shop as soon as possible—don't end up regretting it like I did.
Ignoring knocking sounds while driving is terrifying! As a frequent driver, I once ignored it when the sound grew from faint to loud. The engine started overheating and smoking, eventually stalling on the highway—nearly causing an accident. The consequences included severe cylinder block damage, cracked wear spots leading to oil leaks, and overall power loss with jerky acceleration. Over time, piston rings also fail, reducing compression and making ignition difficult. Delaying repairs not only doubles repair costs but also causes excessive emissions and skyrocketing fuel consumption, burning hundreds more in gas per month. Find a reliable repair shop immediately to avoid bigger troubles.
