Soot Production in Diesel Engines: Internal combustion engines produce soot as a result of incomplete fuel combustion. Ideally, complete combustion in a cylinder would only produce carbon dioxide and water, but no engine is completely efficient.

How is soot particles produced?
Soot is formed during the combustion of hydrocarbon fuels, such as oil, natural gas, and wood. ... Soot particles are formed when gaseous molecules are heated to high temperatures, and they don't easily turn back to gaseous molecules the way water droplets do when they are heated up.
What is diesel soot made of?
Diesel soot particles have a solid core consisting of elemental carbon, with other substances attached to the surface, including organic carbon compounds known as aromatic hydrocarbons.
What causes black soot in a diesel engine?
Incomplete combustion occurs and soot is formed when there is an overabundance of fuel (both diesel fuel and lube oil), insufficient residence time in the combustion zone, and/or non-availability of sufficient oxidants. Over-fueling is the primary cause of black smoke from the exhaust of a heavy duty diesel engine.
What causes soot?
Soot comes from incomplete combustion of a carbon-based material. Any material that can burn can produce soot, including natural gas, LP, wood, oil, candle wax, gasoline, diesel fuel, tobacco smoke, dust, dirt, cooking oils, and carpet fibers.
What is soot diesel?
Lubricant soot is a by-product of diesel combustion. Soot is formed in fuel-rich, cool regions of the combustion chamber and impinges on the cylinder wall, where it is scraped into the engine oil sump by the piston rings. Soot is partially burnt fuel which results in a heterocyclic hydrocarbon particle.
What is the chemical formula of soot?
Initially, these primary soot particles have roughly the composition (C3H)n, and each is actually made up of several thousand carbon atoms. The empirical formula suggests cyclic, highly unsaturated, polycyclic aromatic structural elements.
What kind of fuel is diesel?
Diesel fuel is the common term for the distillate fuel oil sold for use in motor vehicles that use the compression ignition engine named for its inventor, German engineer Rudolf Diesel. He patented his original design in 1892. Diesel fuel is refined from crude oil and from biomass materials.
What is diesel pollution called?
Nitrogen Oxides (NOx) and small particles known as Particulate Matter (PMs) – both prevalent in diesel fumes – combine to contribute to up to 36,000 premature deaths a year in the UK. That's more than tobacco or obesity. The tiny 'PM2.
Where does diesel particulate matter come from?
What is diesel particulate matter? Exhaust from trucks, buses, trains, ships, and other equipment with diesel engines contains a mixture of gases and solid particles. These solid particles are known as diesel particulate matter (diesel PM). Diesel PM contains hundreds of different chemicals.
How do you reduce soot in a diesel engine?
The fix for this is to add a detergent additive to your diesel fuel on a regular basis. A multifunctional treatment like Dee-Zol will clean out the deposits, reduce the amount of fuel burned incompletely burned, and can even extend the life of your DPF (because less soot are being produced at any one time).
Why do tuned diesels smoke?
Black smoke from the tailpipe is soot, which is produced when some fuel hasn't burned properly. Usually this is due to one of two reasons - not enough air to burn the fuel, or not enough time for it to burn. In a tuned vehicle, fuelling is increased to make sure all of the air available is used up for maximum power.
Does diesel burn black?
The internal combustion process in diesel cars requires a certain mixture of fuel and air. The ratio of fuel and air should be proper, otherwise, the mixture will be too rich, which will result in black smoke.
How is carbon soot formed?
Carbon soot is produced by incomplete combustion caused by humans as one of the major sources of soot from burning coal, wood, and oil for industries, and brush fires for agriculture. Natural forest fires can also contribute soot to atmospheric aerosol, and deposits on snow cover.
Where is soot found?
Soot is a byproduct of burning fossil fuels, particularly coal. It is emitted by a variety of sources, including burning coal for electricity or industrial fuel, manufacturing, oil refining, and motor vehicles. Soot is released into the air as either extremely small particles or liquid droplets.
What compound makes up black soot?
Black soot. Soot, sometimes called lampblack or carbon black, is a fine black or brown powder that can be slightly sticky and is a product of incomplete combustion. A major component of soot is black carbon (see below). Since soot is sticky, it tends to stick to exhaust pipes and chimneys where the combustion occurs.
