What Does It Mean When a Diesel Engine Emits White Smoke and Lacks Power?

[Harry]

Diesel engine emitting white smoke and lacking power can be caused by: 1. Delayed fuel injection timing, where the cylinder temperature has already dropped during injection, causing some diesel to remain unburned and turn into oil vapor, resulting in white smoke; 2. Low cylinder pressure, where wear on the valves, piston rings, or cylinder liners leads to insufficient compression pressure; 3. Poor fuel injector atomization, causing incomplete combustion of diesel, which then mixes with high-temperature exhaust gases from normally operating cylinders in the exhaust pipe, resulting in white smoke. Engine maintenance methods include: 1. Using high-quality engine oil; 2. Using qualified coolant; 3. Regularly cleaning the radiator scale; 4. Periodically removing carbon deposits from the engine.
