What Are the Solutions for Black Smoke Emission from Large Pump Diesel Vehicles?
1 Answers
Excessive dust and particulate matter in the air can clog the filter element of the air cleaner, increasing intake resistance and leading to insufficient air intake. For dry-type air cleaners, use high-pressure air to blow away dust and debris; for wet-type air cleaners, replace the oil and clean them. If the fuel grade is incorrect, the viscosity is inappropriate, or the fuel quality is problematic, it may be difficult to ignite, causing the engine to emit black smoke and easily form carbon deposits in the combustion chamber. This can result in a slow rise in the fuel pump's supply pressure, prolonging the fuel injection process, affecting fuel atomization, and causing unstable engine speed with intermittent black smoke emission.
