What are the manifestations of incomplete gasoline combustion?
2 Answers
Incomplete gasoline combustion manifests as black smoke from the exhaust pipe, a strong gasoline smell in the exhaust, increased fuel consumption, and reduced engine power. Causes of incomplete gasoline combustion: 1. Long-term low engine speed, leading to carbon deposits in the engine area, or even sticky, incompletely burned oil residue covering the engine parts; 2. The car's exhaust gas recirculation system, when activated during driving, reintroduces some exhaust gases into the cylinder, causing oxygen deficiency in the combustion chamber and resulting in incomplete combustion; 3. Engine misfire, where one of the six combustion cylinders in an engine is not working or functioning poorly, leading to incomplete combustion; 4. Use of poor-quality fuel in daily driving can also affect combustion, causing it to be incomplete.
From my driving experience, I can tell you the signs of incomplete gasoline combustion. Simply put, the car doesn't run smoothly. Common symptoms include black smoke from the exhaust pipe, especially more noticeable during acceleration. You'll also smell a pungent gasoline odor, as if the fuel isn't burning completely. The engine may shake slightly, making the car feel like it's hiccuping, particularly noticeable at startup. Additionally, fuel consumption will be much higher than usual—you'll get a low fuel warning soon after filling up the tank. There's also a significant drop in power, making it hard to speed up when climbing hills or overtaking. If this continues long-term, it not only damages the engine but also causes excessive exhaust emissions that pollute the environment. If you encounter these issues, promptly check the ignition system, such as spark plugs and fuel injectors, or test the air filter. Regular maintenance can prevent these problems.
