Are you talking about the generator, the type that uses diesel or gasoline?
The blue smoke means the engine oil is burning. It is common that when the engine pulls on the cylinder, the cylinder seal becomes damaged. not good, and the piston ring scrapes the oil. The residue is mixed with fuel/gas and burned in the cylinder, and blue smoke is emitted.
If the white smoke is coming from a diesel engine, you need to be careful. This may be caused by water in the cylinder or a water leak when the gasoline engine burns. there are other reasons, too difficult to say.
Gasoline generator
Exhaust
Black smoke
Causes
(1) Use The quality of the. the fuel is poor
Containing many impurities. Impurities clog the fuel injector
which prevents complete combustion in the cylinder and causes black smoke
Also, the engine's fuel injectorhas high pressure during injection
< p>Some fine hard impurities will scratch the inner wall of the fuel injection nozzle. Once the nozzle is scratched, the accuracy of fuel injection is changed.Damaging the fuel injector
This will cause serious damage to the engine. If the fuel injector is damaged
Even if qualified fuel is used, black smoke will still be emitted. Therefore, we should pay close attention to fuel quality.
Selecting qualified fuel is beneficial to the life of the engine.
(2). There is a lot of dust and debris in the environment.
The air filter element
is seriously clogged. The air intake filter is clogged, resulting in a lack of combustion air in the cylinder.
Incomplete combustion. Clean or replace the air filter
and maintain a clean environment.
(3). The
That is, the piston must match the fuel injection during the work process
The time difference between the two will cause incomplete combustion. Black smoke appears. In this case, it is necessary to adjust the engine injection timing and valve clearance.
What is the reason why the gasoline generator exhaust emits white smoke:
(1).
Caused by moisture in the fuel system
. The bottom of the oil storage tank can be emptied
to check for moisture.
(2). When the cylinder valve wears and changes the air flow, white smoke with
smoke rings
will be emitted. At this time, worn parts must be replaced.
(3). Bad atomisting of fuel from the fuel injector
Diesel
Mist droplets
in
Combustion chamber
Does not burn. The fuel injector should be checked
and adjusted to the specified fuel injection pressure.
