What causes the Geely Vision to emit black smoke and lose power?
2 Answers
Geely Vision emitting black smoke and losing power is caused by incomplete combustion leading to excessively high mixture concentration, requiring throttle cleaning and engine carbon deposit treatment. The relevant introduction to engine maintenance is as follows: Cleaning the air filter: The air filter is related to the engine's air intake during driving. If the air filter becomes clogged or accumulates excessive dust, it will hinder engine air intake, and a large amount of dust entering the cylinder will accelerate carbon deposit formation in the cylinder, causing poor engine ignition, insufficient power, and naturally increased vehicle fuel consumption. Removing throttle sludge: Sludge is formed due to carbon deposits from fuel combustion exhaust at the throttle and residues from impurities not filtered by the air filter. Excessive sludge can cause air intake resistance, leading to increased fuel consumption. Cleaning injector carbon deposits: Carbon deposits can cause difficulty in starting, and injector carbon deposits can also lead to fuel passage blockage, deformed gasoline injection, poor atomization, and naturally increased fuel consumption.
My Vision previously had the issue of emitting black smoke and lacking power, which felt terrible. The car was like a sluggish chimney, occasionally shuddering. I remember it was due to prolonged lack of maintenance, causing the air filter to clog and preventing air from entering, resulting in incomplete combustion of gasoline and black smoke. Another possible reason could be a leaking or clogged fuel injector, where excess fuel doesn't burn completely, leading to insufficient engine power and poor performance. Insufficient fuel pump pressure is also a possibility, which can cause unstable gasoline supply. If you encounter this situation, stop driving immediately to avoid damaging more components. Like I did, promptly take it to the shop for inspection, replace the filter, or clean the fuel injection system. Developing a habit of checking every 5,000 kilometers can prevent such issues in advance.
