Does Engine Knocking Need Repair?
4 Answers
Engine knocking requires repair as it can cause certain damage to the engine. It may lead to decreased engine power, a sudden increase in fuel consumption, and in severe cases, deformation or damage to moving parts such as the cylinder walls, pistons, piston rings, valves, connecting rods, and their bearings. Timely repair is necessary. Methods to avoid engine knocking are as follows: 1. Avoid lugging the engine: Driving at high gear with low speed can easily increase engine load, thereby advancing the ignition timing. Since the engine is in a higher gear, the RPM increase is not significant, making knocking more likely to occur. 2. Regular maintenance: Regularly service at 4S shops, including cleaning the fuel system and injectors, removing engine carbon deposits, and changing engine oil, which are methods to maintain the engine in good condition. 3. Avoid overheating: Regularly check the coolant level, inspect and change the engine oil, avoid prolonged aggressive driving, and frequently monitor the water temperature during summer driving. 4. Use high-quality fuel additives appropriately: Some high-quality fuel additives available on the market can also help mitigate engine knocking to a certain extent.
I've been driving for decades and encountered quite a few engine knocking issues. This is definitely not a minor problem and needs immediate repair. Knocking refers to that abnormal knocking sound the engine makes during operation, which sounds like 'clattering'. It's usually caused by poor fuel quality or ignition system malfunctions. If not addressed promptly, it can lead to spark plug burnout, piston ring damage, and in severe cases may even cause complete engine failure. For repairs, I recommend first checking the spark plugs and carbon buildup situation, then trying higher quality fuel; if it persists, you'll need to find a professional technician to adjust ignition timing or replace components. Early repairs are absolutely cost-effective - delaying not only increases fuel consumption but also affects the vehicle's overall lifespan. I personally experienced this once when I didn't repair it and ended up spending over ten thousand yuan later on replacement parts. The key is safety - when knocking occurs, the car's power becomes unstable, creating significant risks during high-speed driving. Never ignore it for temporary convenience.
I usually enjoy tinkering with my car, and I've looked into this knocking issue—it definitely needs fixing. It's not because the car is old or anything; it's more related to the fuel. For example, using lower-octane gasoline can easily cause knocking sounds. The repair is quite simple. First, do a basic check yourself: see if the spark plugs are clean and if the fuel filter is clogged. If that doesn't help, take it to a shop to clean the intake system. If left unfixed, it might seem fine in the short term, but over time, it will accelerate engine wear. Like my car—I ignored it at first, and not only did fuel consumption skyrocket, but I ended up needing a major engine overhaul, wasting thousands of dollars. Luckily, it's fixed now, and the car runs much smoother. My advice? Don’t hesitate—act as soon as you notice unusual sounds. Protecting your car means protecting your wallet.
I really value vehicle safety, and engine knocking definitely needs to be repaired—don't take it lightly. Knocking sounds like a 'knocking' noise, mainly caused by ignition or fuel issues. If not repaired in time, it can gradually damage internal engine components like pistons and valves, potentially leading to malfunctions over time. For repairs, I usually take it to an authorized repair shop to have professionals inspect and clean carbon deposits and adjust the electronic control system. It's not expensive, just a few hundred bucks, much safer than breaking down on the road. Remember, safety first—when knocking occurs, the car's performance declines, making it prone to losing control in rain or on curves. Fixing it early saves hassle and effort.
