What kind of smoke comes from a diesel engine?
Blue Smoke: Blue engine smoke is the rarest type of smoke emanating from a diesel engine. The presence of blue smoke is an indication of burning oil. Blue smoke should not be ignored but is common when starting an engine in a cold weather.
When to shut down a diesel engine with smoke?
No matter the color of the smoke it is not something you should ignore. A properly working and maintained diesel engine should produce no visible smoke. Make sure to shut down the engine immediately if you encounter excessive smoke as further heat or load could severely damage the engine further.
Why do I have white smoke coming from my engine?
If white smoke occurs during a startup in freezing temperatures, then goes away, it usually indicates frozen deposits of soot which expanded around the rings then burned away once the engine warmed up. The use of glow plugs during cold starts and/or the use of a flushing solvent to remove engine sludge is recommended.
What happens after 125, 000 miles on a car?
If you look at any factory-recommended service intervals, after 100,000 miles they cease to exist. 125,000 miles is almost five times around the planet. With all of the warranties expired, it is up to the owner and their repair shop to keep it rolling. Here are 13 items you should service.
How many miles does it take for a car to burn oil?
For example, BMW tells owners it’s normal for some of its engines to burn a quart of oil in fewer than a thousand miles. In a tip sheet to fleet-vehicle operators, GM says normal consumption “can be in the range of one quart within 2,000 miles on a properly driven and maintained vehicle.”.
Can a fuel injector be cleaned at 250, 000 miles?
Fuel Injector Cleaning: At 250,000 miles, more than 10,000 gallons of fuel have been pumped through very small holes in the injectors. An injector’s needle and seat also have been crashing into each other millions of times. Carbon can build up on the caps and the fuel spray pattern might not be what it once was.
When to use glow plug for diesel engine?
The use of glow plugs during cold starts and/or the use of a flushing solvent to remove engine sludge is recommended. Black smoke, unlike white smoke, contains a high concentration of carbon exhaust particles. The combustion of diesel fuel in the cylinders breaks down the long chain of carbon molecules to smaller and smaller molecular chains.
What does blow by mean on a new diesel engine?
A brand new diesel engine running at full load will experience a little bit of blow-by upon startup. Blow-by is a condition where diesel fuel, air and vapor are pushed past the rings into the crankcase of the engine. Correct pressure should be maintained in the cylinder chamber in order for proper combustion to occur.
Why does my diesel engine have blue smoke?
Blue engine smoke is the rarest type of smoke emanating from a diesel engine. The presence of blue smoke is an indication of burning oil. Blue smoke should not be ignored but is common when starting an engine in a cold weather. The oil thins out when it is cold and some could escape into the cylinder and be burnt.
