Description
(54) СПОСОБ ВЫЯВЛЕНИЯ ОСТАТОЧНОГО РЕСУРСА ПОРШНЕВОГО ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ(54) METHOD FOR DETERMINING THE RESIDUAL RESOURCE OF A PISTON ENGINE FOR INTERNAL COMBUSTION
1one
Изобретение относитс к машиностроению , а именно к способам диагностировани дизельных двигателей, в частности к оценке изношенности гильз цилиндров двигател без его разборки.The invention relates to mechanical engineering, in particular to methods for diagnosing diesel engines, in particular to assessing the wear of engine cylinder liners without disassembling it.
Известны способы вы влени остаточного ресурса поршневого двигател внутреннего сгорани путем определени на заданном тепловом режиме в технически исправном двигателе интенсивности износа цилиндро-поршневой группы по концентрации частиц железа в системе смазки 1.Methods are known for detecting the residual life of a piston internal combustion engine by determining, on a given thermal mode in a technically sound engine, the wear rate of a cylinder-piston group based on the concentration of iron particles in the lubrication system 1.
Однако известные способы отличаютс невысокой точностью.However, the known methods are characterized by low accuracy.
Цель данного изобретени - повышение точности оценки изношенности гильз цилиндров двигател без его разборки путем исключени вли ни режимов работы двигател .The purpose of the present invention is to improve the accuracy of estimating the deterioration of engine liners without disassembling it by eliminating the influence of engine operating conditions.
Поставленна цель достигаетс тем, что дополнительно определ ют величину отношени концентрации частиц железа в системе смазки к расходу топлива за контрольный период работы двигател и по величине отклонени относительной концентрации от номинального значени вы вл ют интенсивность износа цилиндро-поршневой группы.This goal is achieved by additionally determining the ratio of the concentration of iron particles in the lubrication system to fuel consumption for the control period of the engine and the magnitude of the deviation of the relative concentration from the nominal value reveals the wear intensity of the cylinder-piston group.
а по последнему устанавливают остаточный ресурс двигател .and according to the last install the residual engine life.
На фиг. 1 представлена номограмма дл оценки технического состо ни двигател и прогнозировани его остаточного моторесур5 са; на фиг. 2 - график изменени массы железа , сн того с деталей двигател за контрольный период (60 моточасов) при различной степени износа гильз цилиндров и разной мошностной загрузке( 40,60 и 80% от 10 NejTiax); на фиг. 3 - график изменени массы железа, сн того с деталей двигател за контрольный период (60 моточасов) по отношению к 1 кг расхода топлива при различной степени износа гильз цилиндров и разной мошностной загрузке (40,60, 80/о Нвпих); 15 на фиг. 4 - номограмма изменени массы сн того железа в зависимости от загрузки двигател : 1 - 400/о Nema«; 2 - 60% Nemaxi 3 - 80% Г, 2, 3 - то же, после замены колец.FIG. Figure 1 shows a nomogram for assessing the technical condition of an engine and predicting its residual engine life; in fig. 2 is a graph showing the change in mass of iron removed from engine parts over the control period (60 hours) at various degrees of wear of cylinder liners and different load capacity (40.60 and 80% of 10 NejTiax); in fig. 3 is a graph showing the change in mass of iron removed from engine parts during the control period (60 engine hours) with respect to 1 kg of fuel consumption at various degrees of wear of cylinder liners and different engine load (40.60, 80 / o Nvpih); 15 in FIG. 4 - nomogram of mass change of iron removal depending on the engine load: 1 - 400 / o Nema "; 2 - 60% Nemaxi 3 - 80% G, 2, 3 - the same, after replacing the rings.
