Abstract
Description
Изобретение относится к области двигателестроения и может быть использовано для безразборной очистки цилиндро-поршневой группы и газовыхлопного тракта двигателей внутреннего сгорания от нагара. The invention relates to the field of engine building and can be used for in-place cleaning of the cylinder-piston group and gas exhaust tract of internal combustion engines from soot.
Известен способ очистки поверхностей деталей дизельного двигателя от нагара, в котором двигатель работает на водотопливной эмульсии, принятый за прототип. A known method of cleaning the surfaces of parts of a diesel engine from soot, in which the engine runs on a water-fuel emulsion, adopted as a prototype.
Недостатками прототипа является использование специального стенда для приготовления водотопливной эмульсии и возможность использования такого способа только при температуре выше температуры замерзания воды, т.е. только при положительной температуре окружающей среды. The disadvantages of the prototype is the use of a special stand for the preparation of a water-fuel emulsion and the possibility of using this method only at temperatures above the freezing temperature of water, i.e. only at positive ambient temperatures.
Цель изобретения - разработка универсального способа безразборного удаления нагаров из двигателей внутреннего сгорания, как дизельных, так и карбюраторных, путем использования композиционной смеси присадок к моторному топливу. The purpose of the invention is the development of a universal method of in-place removal of soot from internal combustion engines, both diesel and carburetor, by using a composite mixture of additives to motor fuel.
Сущность изобретения заключается в том, что в топливо в количестве 0,01-0,015 об. % вводится композиционная смесь, содержащая присадку на основе тетраэтоксисилоксана с примесью продуктов его гидролиза - димера, тримера и тетрамера, содержащая дополнительно 0,1-1,0 об.% ацетилацетоната металла. The invention consists in the fact that in the fuel in an amount of 0.01-0.015 vol. % is introduced a composite mixture containing an additive based on tetraethoxysiloxane mixed with products of its hydrolysis - dimer, trimer and tetramer, containing an additional 0.1-1.0 vol.% metal acetylacetonate.
Изобретение иллюстрируется следующими примерами. The invention is illustrated by the following examples.
Испытания проводили на установке для испытания моторных масел на базе дизеля Д-21. На первом этапе испытаний в течение 10 ч двигатель работал на дизельном топливе Л (ГОСТ 305-82) на масле М10В2 (ГОСТ 8581-78) в режиме ускоренного нагарообразования на двигателях цилиндро-поршневой группы. После чего двигатель вскрывали и проводили оценку нагарообразования на поршне, определяли толщину и состав нагара на днище поршня и головке блока цилиндров. Двигатель собирали.The tests were carried out on the installation for testing engine oils based on the D-21 diesel engine. At the first stage of testing for 10 hours the engine was running on diesel fuel L (GOST 305-82) using M10B 2 oil (GOST 8581-78) in the mode of accelerated carbonization on engines of a cylinder-piston group. After that, the engine was opened and carbon deposit formation on the piston was evaluated, and the thickness and composition of the carbon deposits on the piston bottom and cylinder head were determined. The engine was assembled.
На втором этапе двигатель работал на топливе Л и том же масле, что и на первом этапе. В топливо вводили 0,015% композиционной смеси, содержащей присадку на основе тетраэтоксисилоксана с примесью продуктов его гидролиза - димера, тримера и тетрамера, дополнительно содержащую 0,5 об.% ацетилацетоната железа (III). Двигатель работал на различных нагрузках и разное время. At the second stage, the engine ran on fuel L and the same oil as in the first stage. 0.015% of a composite mixture containing an additive based on tetraethoxysiloxane with an admixture of its hydrolysis products - dimer, trimer and tetramer, additionally containing 0.5 vol.% Iron (III) acetylacetonate was introduced into the fuel. The engine worked at different loads and at different times.
После каждого испытания двигатель вскрывали и оценивали толщину нагара. Результаты приведены в табл. 1. After each test, the engine was opened and the thickness of the deposit was evaluated. The results are shown in table. 1.
По аналогичной двухэтапной методике было испытано влияние ацетилацетонатов различных металлов на очистку камеры сгорания от нагаров при работе двигателя на топливо Л и различных маслах. На первом этапе проводили ускоренное нагароотложение на двигателе, а на втором - удаление нагара. При этом на втором этапе испытаний двигатель работал на том же масле, что и на первом этапе в течение 1 ч при нагрузке 75% от номинальной (N е = 11 кВт, n = 1600 мин). Using a similar two-stage technique, the effect of various metal acetylacetonates on the cleaning of the combustion chamber of soot when the engine was running on fuel A and various oils was tested. At the first stage, accelerated deposition was performed on the engine, and at the second stage, carbon was removed. At the same time, at the second stage of testing, the engine was running on the same oil as at the first stage for 1 h at a load of 75% of the nominal (N e = 11 kW, n = 1600 min).
Результаты испытаний представлены в табл. 2 The test results are presented in table. 2
