Normally it points to fuel not being entirely burnt in the cylinder, or too much fuel being delivered. Cause could be malfunctioning injectors, or some restriction in the air inlet, like a clogged air filter.
White smoke means water, blue/black smoke means oil, black smoke can also mean the fuel mixture is too rich.
white smoke from diesel exhaust generally means you have engine coolant leaking internally in enginevery rarely , white smoke can indicate a problem with the turbo
Unburnt fuel.
Black smoke from diesel engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. The main causes are normally a nakered air filter that isn't letting enough clean air into the engine to mix with the diesel, a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much diesel into the engine, and causing black smoke due to excess burning. The last cause could be the engine's fuel injector which should normally create a fine mist spray of diesel to be burnt. if its faulty it could either not be spraying enough fuel into the chamber, or too much.
you mean the car Ҽxhaust?
its burning oil :(
It means to smoke weed errday.
It can be a number of different things. The color of the smoke will often tell you a lot about what's wrong. Generally speaking, with gas or diesel, if the smoke is black, that would indicate that the engine is getting too much fuel. If the smoke is blue, it's probably from engine wear and the color is from oil burning. You can also get white smoke which might mean there is water leaking into the cylinders on a gas engine, and either a cold engine or poor compression on a diesel. There are a lot of other causes and variables. too. For instance, if your engine was getting too much fuel, the excess fuel might seep into the oil pan and mix with the oil. Then you might have black with blue smoke, or just black, or just blue. So, there are a number of things to check.
It means to smoke on weed, it comes from the Jamaican Patois
"BLUE" smakoe on a diesel can be a little confusing, made worse by what era the engine comes from and if the emisions control stuff in the exshaust has been removed. Old school heavy duty deisel engines for large trucks and rail locomotives, 1902 untill 1980's will put out green blue acrid smelling greasy smoke when cold or allowed to idle to long. Normal. All diesels but out a pull of black or white smoke at start up. Newer Diesel engines will only smoke blue if they have a bad injector or are worn out. For the blue to get through the polution control stuff since about 2008 means there is something really wrong.
If its black smoke you are burning oil possibly due to oil getting in your exhaust by tilting the lawnmower on its side or your rings are allowing oil by.
"g" Would be the object's constant of gravitational attraction (acceleration), this is dependant on the mass of the object.
