No. This means that the manifold has an exhaust leak.
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.
engine tune just a major service then maybe a new exhaust system
The name is soot.
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.
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.
Nitrogen, carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, and soot.
Soot is the black residue that forms when organic matter is incompletely burned. Though it can be found in chimneys, it can also come from sources like car exhaust and candles.
either its running to lean or you have a bad exhaust valuve
Soot particles are formed from diesel exhaust through incomplete combustion of fuel, where carbon-rich particles are emitted instead of being fully burned. This incomplete combustion can be caused by factors such as insufficient oxygen supply, improper fuel-to-air ratio, and high engine loads. Soot particles can then accumulate and be released into the air as part of diesel exhaust emissions.
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.
