The appearance of smoke is expected every time we operate any vehicle with an internal combustion engine, not just cars from popular to high-end. Burning the mixture between air and fuel will create pressure and by-products such as CO2 and carbon black.

And of course, the engine can’t keep these substances inside and has to be discharged outside and smoke.
However, it is expected only when the smoke is very pale or colorless. And if the color produced is white, it means that your car has a problem, especially when white smoke from exhaust when accelerating.
Car Exhaust Smoke Colors
The color of car smoke makes more sense than you imagine. Because during the car’s operation, the waste that comes out is relatively easy to get shade from other agents and change into a different color.
So it is not wrong to say that just by determining the color of the exhaust smoke, we can partly guess the car’s problem.
+Light white or colorless
It is the usual color of the smoke that a normally functioning vehicle kit with stabilizer components will release into the environment. On rainy or snowy days, the color may be a little darker due to water vapor but still within the allowable limit.
+Blue or gray
Any color but pale white or colorless are all warning signs to look out for, and of course, blue or gray smoke is no exception. Because blue or gray exhaust smoke only appears when the car is likely to have an oil leak, and your engine is on fire.
+Milky white/dark white
If the white of the smoke becomes more opaque or turns milky, there is a high chance that the vehicle has a problem with the head gasket, an eye fluid leak, or worse, cracked and broken cylinder heads.
+Black
Black exhaust fumes can appear when the vehicle is burning too much fuel. The reason for this can be from a clogged air filter, malfunctioning fuel injection system, clogged manifold, or many other problems.
White Smoke From Exhaust When Accelerating: Common Causes
If you had to list in detail the reasons why white smoke appears when we accelerate, then you must spend a lot of time reading dozens of different pages of text.
There are many reasons why smoke goes from colorless to white when we operate the car in general and when accelerating in particular. So below, we will give you information about some of the common causes of this phenomenon.
+Condensation
If the problem is only in the capacitor, you are fortunate because this is not a highly complex problem, and we can easily solve it quickly.
Usually, in cold climates or frequent rain, condensation is often relatively easy to see. When accelerating and when starting, you will also see white smoke appear. If the condensation intensity is low, the smoke will be different from usual. As for the high power of condensation, the turning white is understandable. Or cars that don’t start for a long time are also prone to this situation.
This phenomenon can be simply that when warm or hot exhaust gas meets cold outside air, the water molecules will quickly change from vapor to liquid form and cause condensation and water vapor.
The steam will mix with the smoke and cause discoloration.
+Oil leak
Oil leakage is also one of the leading causes of white smoke from the exhaust when hastened.
Usually, the oil will be separate from the fuel to avoid reactions. But if engine oil suddenly leaks out of valve seals or piston rings, the solvent will certainly mix with the power in the internal combustion chambers of the vehicle.
Once a liquid such as oil is in a high-temperature environment, smoke will begin to form, and that is why we see the unusual white smoke color.
Usually, to fix this error, it will cost you a lot to fix an oil leak or even replace the whole pipeline system.
+Leakage of coolant
It can be that the leakage of liquids is one of the leading causes of white smoke from the exhaust when hastened. So in addition to oil leaks, you will likely encounter another problem: a coolant leak.
Unlike many other causes, a coolant leak is easy to spot because white smoke and some other characteristics will also appear when this liquid leaks. The most typical is if you see white smoke coming out continuously and have a sweet smell, it is definitely because the car’s coolant has leaked.
Coolant often leaks usually due to a crack in the cylinder head or even the engine block. In this case, you will most likely have to spend a long time rebuilding the entire engine.
+Poor quality fuel injector
If the fuel injectors are faulty such as stuck open or leaking from the sealing ring, more fuel will flow into the cylinder and combustion chamber than usual.
Many people may mistakenly believe that more energy will increase performance when we add zero through the camshaft .
But the reality is different; too much fuel will lead to excess. This excess fuel cannot burn properly in the engine and instead comes out as white smoke.
Frequently Asked Questions(FAQ’s)
+Does white smoke always mean blown head gasket?
While sometimes it may not be, white smoke is often one of the most common symptoms of a problem with your vehicle’s head gasket.
+Can I drive with white smoke from the exhaust?
You can still move as usual, but to make sure you don’t encounter any problems, we should take the car to have it checked as soon as possible.
+Does car smoke have a strange smell when broken?
Some problems will create color and typical car exhaust odors such as sweet or burnt odors.
Conclusion
When hastened, white smoke from the exhaust is relatively dangerous if maintained long-term without any intervention. So through this article, we hope you have gained the knowledge to intervene and handle this problem promptly.
