(54) СПОСОБ ДИАГНОСТИКИ ДИЗЕЛЯ(54) METHOD OF DIESEL DIAGNOSTICS

1one

Изобретение относитс  к способам диагностики внутреннего сгорани  по составу токсических компонентов.This invention relates to methods for diagnosing internal combustion according to the composition of toxic components.

Известны способы диагностики,заключающиес  в том, что отбирают заданное количество отработавших газов , вьвдел ют из них конденсат,провод т химический анализ и сравнивают результаты с эталонными И .Diagnostic methods are known that take a given amount of exhaust gases, extract condensate from them, carry out chemical analysis and compare the results with reference I.

Однако такой способ требует сложной аналитической аппаратуры, его осуществление сложно и сравнительно длительно.However, this method requires sophisticated analytical equipment, its implementation is difficult and relatively long.

Цель изобретени  - ускорение диагноза .The purpose of the invention is to accelerate the diagnosis.

Указанна  цель достигаетс  тем, что после выделецр  конденсата определ ют его количество, а химический анализ провод т над Конденсатом с определением водородного числа кислотности и последнее сравнивают с эталонным.This goal is achieved by the fact that after the separation of the condensate its amount is determined, and chemical analysis is carried out over the Condensate to determine the acid number of the acidity and the latter is compared with the reference one.

Способ диагностики дизел  осуществл етс  следунвдим образом.A method for diagnosing a diesel engine is performed in the following way.

С использованием данных анализа продуктов выхлопа и данных первичной ее .регулировки, последн   тарируетс  по водородному показателю (рН) кислотности конденсата продуктов выхлопа и по количеству конденсата,причем в процессе работы дизел  периодически осуществл ют определение РН конденсата выпускных газов и провод т зат жку иглы форсунки при рН 2-2,5.Using exhaust gas analysis data and its primary adjustment data, the latter is calibrated by the pH value (pH) of the condensate acidity of the exhaust products and by the amount of condensate, and the exhaust gas condensate pH is periodically measured during the operation of the diesel engine and the injector needle is tightened at pH 2-2.5.

Химический состав окислов азота, содержащегос  в выхлопных газах дизел , зависит от температуры и коэффициента избытка воздуха оС. Дл  ди0 зелей вС 1,5-2,0.The chemical composition of nitrogen oxides contained in the exhaust gases of a diesel engine depends on the temperature and air excess factor. For dislocations in the SA 1.5-2.0.

Данный способ диагностики форсунки дизел , предусматривает охлаждение газов до комнатной температуры, поэтому применительно к указанным This method for diagnosing a diesel nozzle, provides for the cooling of gases to room temperature, therefore, in relation to these

5 услови м протекают следующие процессы .5 conditions are the following processes.

Чем выше температура, тем больше веро тность образовани  N0. При выходе из цилиндра газы охлаждаютс  за счет теплообмена отводной трубы с окружающей средой, при достижении температуры ниже 140°С в них образуетс  NOi. При более высоких температурах NOa диссоцирует на N0 и Qi,npH 620с NOa практически не существует 2NO + O L5 -2NOi. .The higher the temperature, the more likely the formation of N0. When leaving the cylinder, the gases are cooled due to the heat exchange of the discharge pipe with the environment, when the temperature reaches below 140 ° C, NOi is formed in them. At higher temperatures NOa dissociates into N0 and Qi, npH 620c NOa practically does not exist 2NO + O L5 -2NOi. .
