polttoainejäämät
Polttoainejäämät refers to the residual substances left behind after the combustion of fuels. These can include unburnt fuel, partially combusted hydrocarbons, soot, ash, and various chemical byproducts depending on the type of fuel and the efficiency of the combustion process. In internal combustion engines, for example, incomplete combustion can lead to the formation of carbon deposits, often referred to as "engine sludge" or "carbon buildup," within the engine's cylinders, pistons, and valves. These residues can negatively impact engine performance, increase fuel consumption, and lead to increased emissions of pollutants.
Different types of fuels produce varying amounts and types of residues. For instance, the combustion of fossil
