White Smoke Diesel Generator Solution – Emergency Diesel Generators
Diesel generators emitting white smoke indicate water contamination in the fuel system, which leads to milky white exhaust smoke as water mixes with the fuel. Key steps to diagnose and fix include: checking the fuel supply for contamination, inspecting for leaks, tightening hoses, replacing fuel filters, and polishing the fuel to remove water. If not addressed, the generator may struggle to maintain load. Continuous black smoke suggests issues with fuel input and filters, while blue smoke may indicate the generator's age or a need for major repairs. Proper maintenance is crucial to prevent failure.
Diesel Generator white smoke when running indicates water in the fuel. Generator could be running without issue and then the clear exhaust smoke begins to turn white and then stays white means that there is some water within your fuel system. This typically happens with diesel generators when microscopic amounts of water or a leak enters somewhere within the fuel system.
Fuel in the cylinders is burning off with the water content causing the clear exhaust smoke to turn a milky white in appearance. If this is allowed to continue you’ll find the generator begins to hunt and may have difficulty supportingload and could drop the load.

• Lastly -Check the injectors for replacement due to age and contamination.
BLUE SMOKE
BLUE SMOKE
• First – Is the generator OLD?
• Second – has the generator run for over 10,000 hours?
• Third has the generator never been serviced properly for years?
• Forth – replace the head gasket and any gasket/seal around the fuel and oil filters as soon as possible.
• Lastly if the BLUE SMOKE continues after all of the above have been done, then your generator requires a major re-build due to excessive run hours.
• Failure to replace ALL the ABOVE will cause major generator failure.
