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