What are the consequences of engine knocking?
3 Answers
Engine knocking can produce the following effects: 1. Decrease in engine power. 2. Increase in temperature. 3. Increased load and wear on internal engine components. 4. Increased formation of carbon deposits inside the engine. 5. Deformation of internal engine components due to increased temperature. 6. Increased heat carried away by the coolant. The following are the causes of knocking: 1. Excessive ignition advance angle. 2. Fuel quality does not meet the engine's requirements. 3. Reduced space in the engine combustion chamber. 4. Damaged knock sensor or knock sensor mounting screws not tightened to standard torque. Knocking refers to the abnormal combustion phenomenon inside the engine combustion chamber, causing the internal pistons to strike the cylinder.
Engine knocking is no joke. I've seen it firsthand how it can completely destroy internal engine components. Parts like spark plugs or pistons can deform or even crack due to the abnormal high-pressure shock waves it creates. Over time, cylinder walls will develop scratches and wear, leading to noticeably reduced power output and sluggish acceleration - the car feels like it's lost all its pep. Fuel consumption also inexplicably skyrockets. A friend of mine neglected to fix his knocking engine, and it suddenly stalled midway, nearly causing an accident. Actually, simple preventive measures like checking the ignition system or switching to higher-quality fuel could have avoided this. Don't wait until the cost becomes prohibitive. Safety first - if knocking occurs, pull over immediately for inspection. Otherwise, repair bills could easily exceed tens of thousands, which just isn't worth it. Regularly listening for abnormal knocking sounds from your engine can help you avoid major trouble down the road.
The consequences of engine knocking are really tough. My car had this issue before, and the power dropped immediately, making it crawl like a snail when climbing hills. It felt like the engine was fighting internally. This problem not only accelerates wear on engine components like pistons or piston rings but also leads to excessively high oil temperatures, burning more fuel. My monthly fuel expenses increased significantly. The most annoying part was the increased noise, sounding like metal clashing, which was distressing to hear while driving. If left unchecked, it could even pose a fire risk—rare but real. Once I ignored it, and the mechanic said the entire engine block needed replacement, costing me several thousand dollars. I recommend regular oil changes and using higher-octane fuel for prevention—don’t be like me, acting wise after the event.
