If the engine is diesel, no that is normal. If the engine is gasoline, yes it is probably burning oil.
A running Diesel engine releases soot in its exhaust. Another word for soot is particulate pollution - as soot consists of small particles.
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
engine tune just a major service then maybe a new exhaust system
A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.
burning oil
The present invention relates to a soot afterburner for amotor vehicle exhaust system. More particularly this invention concerns an electrically powered device that burns soot separated out of the exhaust gas stream of, for instance, a diesel engine.
burning oil
A FAP is a filter on the exhaust system that catches soot particles, which decreases environmental polution. Regeeration is the process of removing the collected particles and soot from the FAP.
No. This means that the manifold has an exhaust leak.
If you have an issue with furnace exhaust in your home and soot is exhaust. Please stop wasting your time here. That is dangerous. Call somebody! Nobody here can tell you what it is with out looking at it.
Exhaust soot is Carbon based molecules that have not reacted to completion in the combustion chamber.We input Hydrocarbon, Air, and Exhaust gas (EGR), and hope that we burn all the hydrocarbon into carbon dioxide and water. If there is not enough oxygen in the combustionchamber for the amount of fuel (through over allowance of EGR or otherwise) then we get soot paticles forming.
I would suspect that you're actually leaking "soot". If the engine is running reasonably well and you're getting black liquid when the engine is cold, it's soot. Engines have to run a little "rich' (extra fuel) when they're cold and that sometimes produces a little carbon in the exhaust. Another thing that happens when an engine is cold, the EXHAUST and muffler are also cold. that causes some of the exhaust gasses to condense on the side of the exhaust system. Since automotive fuels are nothing more than complex hydrocarbons, a good portion of the exhaust gas becomes an oxide of hydrogen that we lovingly call "water". Once the water vapor cools on the exhaust system it condenses and picks up the soot and it all drips out, sometimes out of the back of the exhaust pipe, other times out of the "weep hole" of the muffler. If you feel that you're getting too much soot it might be a good idea to give the vehicle a good "tune-up", other than that, there isn't much to do about it. On the other hand, if it truly IS oil, that's leaking out, you have serious oil burning and it's amazing that the engine even runs.
