14.21. Engine pollution
In operating time the engine and all its systems gradually become soiled even at the correct operation and use qualitative fuel-lubricants, not to mention the poor-quality. How to get rid of these stratifications? For removal of resinous, varnish and other deposits, deposits special solvents are necessary. Such preparations are studied and used more than 70 years. The composition of solvents and cleaners can include oil products (kerosene, low-viscous oil, diesel fuel, light gasoline), aromatic hydrocarbons (benzene, toluene, a xylol, naphthalene, a mix of koksokhimichesky production), alcohols (methanol, the ethanol, some highest alcohols), хлорпродукты (хлорнафталин, хлордифенилоксид, four-chloric carbon, хлорбензол, a dichloroethane, etc.) turpentine, этилацетат, acetone. Sometimes add нафтенат lead, стеарат the aluminum, some vegetable and animal oils and fats, acetic acid or its anhydride, ammoniac connections, etc. The composition of various solvents and cleaners is not identical. The vast majority of them has strong dissolving properties and, unfortunately, affect not only deposits, but also on polymers. Besides, they differ high toxicity and a korroziynost. Therefore it is necessary to choose carefully such products, using a professional advice. The majority of solvents and cleaners are intended for separate units, systems, knots or details and are effective only at observance of appropriate technology of their use. Therefore to carry out cleaning by them follows, or separating these units or details, or in a certain sequence. At first clear fuel system, then – oil as products of cleaning of fuel system can get to oil. However, some firms suggest cleaning of the engine to carry out at the same time, using the latest solvents. After fast (5–10 minutes) cleanings of fuel and oil system on HUNDRED for maintenance of purity of the engine, prevention of accumulation of a various precipitation it is possible to use special "dolgodeystvuyushchy" solvents which periodically add in fuel and oil. Such solvents are intended for resinous substances and do not dissolve varnishes, deposits. For engine maintenance in purity follows more often than it is determined in technical data sheet by service of cars, to replace oil. It is especially important. Operating time of synthetic and mineral oils equally. When using synthetic oil the engine, as a rule, becomes soiled less. Now relatively some additives to oils which as advertizing assures, "reduce wear of the engine, increasing capacity and profitability". It is a question of antiiznosny additives and additives (modifiers of a friction and metalplating additives). The essence of their action consists that they get into microcracks, forming on a metal surface a film protecting from wear. At mechanical wear gaps increase, pressure in oil system falls, the compression in cylinders decreases, fuel consumption and engine oil grow. "Salutary" properties of lubricants into which structure the high-dispersed additives are entered, are known for a long time. In engine oils the kopressiya in cylinders and pressure in oil system at the expense of reduction of gaps owing to what fuel consumption and oils on burning out go down can really increase input of metal additives. The friction modifier to which the molybdenum disulfide belongs, for example, at the same time reduces factor of a friction a little. Antiiznosnye and additives to oils for worn-out engines can be used additives, but to choose them it is necessary attentively not to damage to the engine. Not забывйте that noisy advertizing becomes for this purpose, чтобя to sell the goods, despite its quality. |
