Problems From The Emissions System In A Car
Posted on: 27 August 2017
Are you concerned because your vehicle has been releasing large amounts of dark smoke from the muffler lately? You are likely dealing with an emissions problem that can be caused from numerous things being wrong with the car. It is wise to repair an emissions problem fast because it can lead to several harmful chemicals getting into the air, which is harmful to the environment. Getting an emissions test for your vehicle is the first step that should be taken to resolve the problem. The content below will give you more information in regards to what might be causing your car to produce so much black smoke.
1. The EGR Valve is Damaged
An important part of your car is the Emissions Gas Recirculation (EGR) valve. The reason why is because it plays a large role in the amount of smoke that is able to escape out of the muffler. The black smoke that you see might be due to the EGR valve being in a bad condition. You can find out if the valve is the root of the problem when an emissions test has been performed. A bad EGR valve can be replaced if it is necessary.
2. A Replacement Catalytic Converter is Needed
The catalytic converter in your car is the most important part when it comes to emissions. If the converter is damaged and doesn't work properly, it can cause excessive amounts of black smoke to come out of the muffler. A catalytic converter is used for catalyzing gas and harmful chemicals before they make it out through the muffler. When the converter is fully functional, the smoke coming out of the muffler is usually a lighter color. Ask a mechanic if your car is in need of a new catalytic converter and get it installed as soon as possible.
3. The Purge Solenoid Doesn't Function Properly
The purge solenoid is another one of the important parts of an emissions system. The solenoid gives burned off fumes a place to escape into before they are release into the atmosphere through the muffler. Once the harmful fumes are inside of the purge solenoid, they are sent into the intake stream in your vehicle, which is where they can be absorbed in a part called the charcoal canister. It is possible that the purge solenoid has stopped opening and closing as it should. A mechanic, such as from Silver Star Motors Mercedes-Benz Specialists, can attempt repairing the solenoid, but will have to replace it if repairs are not possible due to excessive damage.
