I feel that the car is getting fleshy.

I feel that the car is getting more and more fleshy, because the engine has serious carbon deposition, the spark plug fails, the air filter needs to be replaced, and the ignition system fails.

1, engine carbon deposit is serious.

Generally speaking, carbon deposits will appear on the intake valve, throttle valve and piston top. It may lead to difficulties in ignition, increased fuel consumption and idling jitter. There are many ways to clean up carbon deposits, such as using fuel cleaner, removing the throttle and cleaning.

The spark plug is broken.

Spark plug is a relatively small but important component. There may be phenomena such as excessive gap between electrode plates and carbon deposition, which will affect the normal ignition procedure. Replacing the spark plug is not complicated. You can replace the spark plug yourself.

3. The air filter needs to be replaced.

The air filter is like a mask used by people, which can prevent particulate impurities in the air from entering the air intake system and wearing the piston and cylinder. This will also lead to insufficient combustion of combustion gases. In this way, the phenomenon of carbon deposition will increase exponentially, and the car will also have insufficient power.

4, ignition system failure

There may be phenomena such as easy flameout when starting, engine weakness when accelerating, engine jitter when stopping, etc. The vehicle ignition system is complex, including battery, distributor, ignition coil, spark plug and so on. If you can't rule out which part is damaged, you can seek the help of the maintenance master.

Matters needing attention in automobile maintenance

Use special cleaning agent for automobiles and low alkalinity soap for cleaning. When cleaning polished metal parts, carbon cleaner should be used, and dirt should not be scraped off with hard tools. Waxing regularly to avoid oxidation of coating.
