What Causes Diesel Engine Power Loss and Black Smoke During Acceleration?

[KateAnn]

This is mostly caused by incomplete combustion due to uneven or excessive fuel supply to each cylinder, insufficient air intake, poor atomization, or premature injection timing. Under high-temperature and oxygen-deficient conditions in the combustion chamber, unburned diesel decomposes and polymerizes to form carbon smoke, which is not pure carbon but rather tiny polymer particles. These solid carbon particles react much slower than vaporized fuel, failing to burn completely and being expelled as black smoke. Therefore, regular vehicle maintenance is essential. Below is an introduction to car maintenance: 1. Introduction to Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle servicing. 2. Scope of Car Maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other related components. 3. Purpose of Car Maintenance: The goal of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent malfunctions, slow down deterioration, and extend the service life.
