For a long time, people thought that the amazing progress in cars was linked to huge clouds of exhaust fumes and thick smoke. But these days, with catalytic converters and particulate filters, you shouldn’t be able to smell any exhaust fumes coming from your car at all.
Thick clouds of smoke are not as common as they used to be, but black, white, or blue smoke coming from the exhaust doesn’t always mean that your car’s engine is broken. But defects could be the cause of the smoke, and in some cases, colored exhaust fumes could mean that your car’s technology has already been damaged. This guide will teach you what the color of the exhaust smoke means for the engine and what to do if your exhaust is smoking.
White smoke comes out of the exhaust when you speed up.
The exhaust lets out a lot of white smoke, especially in the winter. When the engine is still cold, the exhaust gases may contain water vapor, which makes this smoke. So, when you start the car, it’s normal for the exhaust to let out white smoke. Does your car smoke white and smell like gas? Be careful, though, because these signs usually mean that the cylinder-head gasket is broken. In this case, you should go to a garage right away or fix the damage yourself, because a bad cylinder head gasket can quickly cause engine damage.
Smoke that is black coming from the exhaust
A lot of drivers think that black smoke means that the engine is about to fail. But your car doesn’t have to be on the edge all the time. When the engine is idling or going slowly, soot particles can also settle in the exhaust and cause black smoke. When the engine is run faster, these tiny particles are blown out, making a black smoke cloud. Diesel-powered passenger cars often have black smoke coming from the exhaust.
A dirty combustion engine, like one that doesn’t get enough oxygen, can also cause a compression ignition engine to release a lot of soot and create big black smoke clouds. You should look to see if the air filter is dirty and change it if it is.
The exhaust lets out blue smoke.
Engine oil or unburned fuel in the exhaust gases causes blue smoke. There could be a lot of different reasons for this. A lot of fuel in the exhaust can cause blue smoke when you start your car cold. But this is not harmful at all. Blue smoke can also come from a leaking oil circuit or a bad spray atomization caused by wear on the material or other things. If your car smokes a lot even after long trips, you should definitely take it to a shop to make sure there aren’t any serious problems or defects. WA Auto Parts can also help you find replacement parts and help you with other things.
