It is not normal for the Shifeng New Superstar three-wheeled heavy-duty vehicle to emit smoke when accelerating. Reasons for black smoke emission: Excessively rich air-fuel mixture, excessive engine oil in the fuel, poor sealing of piston rings or crankshaft oil seals, water in the fuel, faulty spark plugs, excessively dirty air filter. Solutions for black smoke emission: For checking and diagnosing an excessively rich air-fuel mixture, focus on inspecting the carburetor and air filter. The mixture of fuel and oil is incorrect, or the wrong type of oil is used. If the mixed fuel contains too much oil or the oil quality is poor, the oil in the combustible mixture cannot be completely burned, resulting in black smoke emission.
