В выхлопной коллектор 7 непосредственно перед турбиной 8 турбокомпрессора предусмотрена подача прес-- кой воды трубопроводом 9.In the exhaust manifold 7 directly in front of the turbine 8 of the turbocompressor, the supply of fresh water to the pipeline 9 is provided.
Способ осуществл ют следующим об- .разом.The method is carried out as follows.
Предварительно производ т демонтаж топливных трубопроводов от штатных: насосов 1 к вторым форсункам 3 цилиндров и монтаж дополнительных трубопроводов 6 в соответствии с преставленной схемой. Затем двигатель перевод т работать на водотопливную эмульсию (приготовленную любым известным способом с помощью известных средств - диспергаторов), содержащую 70% топлива и 30% воды. В процессе работы двигател каждый топливный насос, отрегулированный ранее .на определенный угол опережени подачи топлива до верхней мертвой точки (в границах 3-15 поворота коленчатого вала до верхней мертвой точки), подает водотопливную эмульсию одновременно в два цилиндра: первый поток в свой цилиндр на такте сжати , например за 10 поворота коленчатого вала до верхней мертвой точки в 1-й 1далиндр,и второй поток на такте рас ширени - в .5-й цилиндр, выбранный из услови подачи топлива, в конце такта расширени за 40-75° поворота коленчатого вала до нижней мертвой точки, а именно за 46 дл 5 цилиндрового двигател . При этом подачу топлива осуществл ют практически в одинаковом количественном отношении ,- что достигаетс за счет использовани идентичных штатных топливных насосов, форсунок 2 и дополThe fuel pipelines are pre-disassembled from the standard ones: pumps 1 to the second injectors of 3 cylinders and installation of additional pipelines 6 in accordance with the pre-installed diagram. Then the engine is transferred to work on a water-fuel emulsion (prepared by any known method using known dispersing agents) containing 70% fuel and 30% water. In the course of engine operation, each fuel pump, previously adjusted at a certain angle of fuel advance to the top dead center (within 3-15 crankshaft rotations to the top dead center), delivers a water-fuel emulsion simultaneously in two cylinders: the first flow into its cylinder on the compression stroke, for example, 10 crankshaft rotations to the top dead center in the 1st 1st cylinder, and the second flow at the expansion stroke - in the .5th cylinder selected from the fuel supply condition, at the end of the expansion stroke for 40-75 ° rotation crank ala to the lower dead point, namely 46 to 5 cylinder engine. At the same time, the fuel supply is carried out in almost the same quantitative terms, which is achieved through the use of identical standard fuel pumps, injectors 2 and additional
