Diagnosing Car Problems By The Color Of Your Exhaust Smoke
The color of the exhaust of your car can say a lot about his health. The color of smoke may indicate that something is wrong inside the engine. It can also direct the areas that need immediate attention. For example, you are losing coolant? Are you burning oil? These and other questions, saying what needs to be identified by your car exhaust.
Unfortunately, it lacks most of the people who are familiar with their vehicles. You do not know how to identify them for signs of a problem in their cars "Drain. In this sense we will explain exactly what is involved black smoke, white and blue. This article provides the details necessary to make semi-diagnostic engine-related problems to be solved.
Black exhaust means that
If you notice black or charcoal-colored smoke from the exhaust gas, means this is the air-fuel mixture in the engine area. That is, there is too much fuel into the combustion chamber, and can not be completely burned when the candle lights the mixture.This can happen if the injectors are leaking fuel pump is faulty, or faulty oxygen sensor transmits data to the powertrain control module (PCM).
Why a "too rich" air-fuel mixture will affect the engine performance, this problem will be solved as soon as possible. Exhaust three colors, but black is the least serious. And 'certainly less serious than white smoke.
Which means white discharge
We must first make an important difference. If youStart your car, and there a small piece of white steam from the exhaust, condensation probable cause. This occurs when the residual moisture in the exhaust system. Start the engine warms up, moisture and produces steam that is blown out the exhaust. You will notice that disappears after a few minutes driving time.
White smoke from the exhaust gas is different. This usually means coolant is somehow entering one or more of the combustion chambers, and isburned along with the air-fuel mixture. This often happens when the head gasket develops a leak. This gasket sits between the cylinder head and engine block, and is supposed to prevent coolant from gaining access to the chambers.
At first, a little coolant in the engine may seem harmless. However, this means your car's cooling system is deprived of coolant due to the leak. This can eventually cause your engine to overheat, leading to expensive repairs. If you see white smoke, immediately check the coolant level. Replenish it, if necessary. Then, have a mechanic examine the head gasket, engine block, and cylinder head.
What Blue Exhaust Means
Blue smoke means oil is gaining access to the combustion chambers. Here, too, it is being burned with the air-fuel mixture, similar to coolant when it leaks past the head gasket. Oil can leak into the cylinders in several places. There are guides, valves, seals, and piston rings in your engine that normally prevent fluid from passing. All of them can wear down, however. When this happens, oil may be allowed through.
Sometimes, leaking oil can slowly foul the spark plugs, causing the cylinders to misfire. If this occurs, you'll need to replaced the fouled plugs. Even if the plugs remain unaffected, this problem can still deprive your engine's moving parts of oil for lubrication. Over time, this can lead to damage in the assembly. As with white exhaust, consider blue exhaust a priority that should be quickly addressed.
Many drivers put off needed repairs because the work involved is often inconvenient and expensive. But consider that postponing such work may lead to bigger - and more costly - problems down the road. Addressing known issues now is a worthwhile investment.
