What does blue smoke in diesel engine indicate?
Blue exhaust smoke in a diesel vehicle could still mean oil is being burned, but it could also mean the engine oil is being atomized. This could be caused by: High engine oil levels. Worn out piston rings.
Can a bad diesel injector cause blue smoke?
Constant blue smoke on a turbocharged diesel is unlikely to be caused by worn valve stem seals. Instead, the problem is more likely to be: Diesel fuel contaminating the oil. This may be caused by faulty injector pump and/or lift pump (which allows engine lubricating oil to mix with the diesel).
Is it normal for a diesel to smoke on startup?
Diesel Engines: Get to Know Exhaust Colors As a general rule, some smoke upon initial startup for a few moments is common, Urso notes. “Black smoke is traditionally associated with a rich combustion process or an overload (abnormal mechanical resistance),” he continues.
Why does my diesel generator smoke?
The smoke may be caused by a simple problem, poor combustion efficiency or from excessive idling, stop start operation or short run times. At the other end of the scale, it may be your last chance to act, before a catastrophic engine failure occurs (e.g. piston seizure, valve or turbocharger failure).
What causes blue smoke on startup?
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise.
What does the blue smoke indicates?
Blue/gray exhaust smoke means there’s likely an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.
How do I stop my diesel from going blue smoke?
There are a few low-cost solutions you can try to find the cause of the blue smoke and stop it from coming back. If you suspect you might be burning oil, Stiction Eliminator is an excellent place to start. It’s an efficient oil treatment for both gasoline and diesel engines.
What does blue smoke from exhaust mean?
Blue/gray exhaust smoke means there’s likely an oil leak and your engine is burning oil. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.
How do I stop my diesel generator from smoking?
Install a diesel particulate filter (DPF) A more expensive, but also far more efficient exhaust smoke cleaner for gensets is a DPF, which uses a ceramic filter media. “Instead of 20 to 30 percent reductions of particulate matter as seen in DOCs, DPFs get 90 to 99 percent reductions,” says Plunkett.
Can a bad turbo cause blue smoke?
If your car has a turbocharger, a blown-out turbo may be causing the blue cloud behind your car. A blown-out turbo can be identified by a broken or damaged oil seal. In this case, oil gets sucked into your engine’s combustion chamber. There, oil mixes with fuel and leads to blue smoke.
