What is the reason for the engine noise when the Changan Eado is running?

The reason why the Changan Eado feels noisy when driving is due to severe carbon buildup in the car engine. If the carbon buildup in the car engine is excessive, it is necessary to promptly visit the car's 4S store or a repair shop to clean the engine carbon deposits, which can solve the problem of excessive engine noise. Carbon deposits include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake pipe carbon deposits, etc. Timing Gear: After long-term use of the engine's timing gear, coupled with improper gear gap adjustment and hardening of the gear belt, excessive wear will occur. In severe cases, even the gear teeth may be worn out, causing looseness in the meshing of the gears, resulting in a "clattering" sound when the machine is running. Direct Injection Engine: Direct injection engines tend to be noisier because the fuel injection pressure in a direct injection engine is more than ten times that of a regular engine. This causes the fuel injector to vibrate during high-pressure injection, making it particularly easy to hear a "clicking" sound when the car is idling or driving slowly.

Every time I drive my Changan Eado, I notice a slight ticking sound from the engine when it's running. This could be caused by a loose belt or issues with the ignition system. I've seen similar cases where engine compartment components wear out after prolonged use, especially parts like belts and gears. If not inspected in time, these can develop into bigger problems. I recommend first identifying where the sound is coming from—whether it's from the front or middle—and then taking it to a professional shop for diagnostics on ignition timing or the crankshaft position sensor. Regular maintenance like changing the engine oil and cleaning the air filter can also help prevent such noises. For safety, don't push it too hard to avoid affecting the engine's lifespan. This isn't something to ignore—I delayed addressing it last time and ended up replacing the entire valve train, which was quite costly. In short, addressing it early saves a lot of hassle.

After driving the Changan Eado for a while, I noticed some engine vibration during operation, especially more noticeable during acceleration. I believe this is related to daily driving habits, such as using low-quality gasoline or infrequent maintenance, leading to increased carbon deposits in the combustion chamber. Excessive carbon buildup can cause uneven cylinder pressure, naturally resulting in vibration. When driving, avoid excessive speeding or prolonged idling; it's best to take a highway trip once a month to burn off carbon deposits. In terms of maintenance, timely replacement of spark plugs and cleaning the throttle body are key. Last year, my car had the same issue, and it vibrated severely after the spark plugs aged. Try opening the engine hood yourself to see if there's noticeable vibration; if so, take it to a repair shop to check cylinder pressure or replace parts. Don't underestimate this issue, as it can affect overall performance. Fixing it early saves trouble later.

The Changan Eado engine produces excessive noise during operation, likely due to component aging. For instance, worn bearings or exhaust system components can become particularly noisy at high speeds. Having driven this vehicle for over ten years, I've observed that parts tend to loosen over time. If the noise resembles metal grinding, inspect chassis bolts or suspension components. Maintenance is straightforward: tighten connection points every six months. Safety comes first - don't let the noise worsen to avoid potential failures.
