Определение dispersants в Английский Язык Английский Язык словарь
Dispersants are similar to detergents in that they too are cleanliness agents Chemically, they are different They function like repelling magnets and keep solid particulate (up to 3 microns) contamination and chemical compounds from agglomerating into deposits such as sludge or varnish When either the detergent or dispersant become depleted or "worn out", you will then get sludge or deposits in the engine NOTE: TBN (Total Base Number) is a numerical combination of these two additives (see the TBN section for more details)
