What Causes a China V Vehicle to Emit Black Smoke?

[AnastasiaRose]

The reason a China V vehicle emits black smoke is due to incomplete combustion conversion rates during diesel combustion, among other factors. Below is relevant information: 1. Poor diesel quality: The diesel used does not meet standard performance requirements, leading to poor fuel combustion and black smoke emission. Additionally, inferior diesel quality can damage the diesel filter, causing the diesel inside the engine to degrade, which results in black smoke. 2. Clogged air intake: If the diesel engine's fuel tank is not sealed, prolonged exposure to air can allow impurities and dust from the air to enter the air filter. These particles can clog the air intake, preventing sufficient air supply during diesel combustion, which easily leads to incomplete combustion and black smoke emission. 3. Insufficient compression: One of the conditions for diesel combustion is a pressurized combustion environment. However, wear on components such as valves and piston rings can reduce compression pressure, failing to meet the required combustion pressure. This worsens combustion conditions, leading to black smoke emission from the diesel engine.
