Description
Изобретение относитс к эксплуатации тепловозных двигателей внутреннего сгорани и может быть использовано при их диагностировании.The invention relates to the operation of diesel internal combustion engines and can be used in their diagnosis.
Целью изобретени вл етс повышение точности оценки технического состо ни ци- линдропоршневой группы каждого цилиндра по импульсам давлени в картере.The aim of the invention is to improve the accuracy of the estimation of the technical condition of the cylinder-piston group of each cylinder by pressure pulses in the crankcase.
На чертеже показана диаграмма изменени давлени в картере двигател (верхн крива дл изношенной цилиндропорш- невой группы, нижн - дл новой).The drawing shows a diagram of the pressure change in the crankcase of the engine (upper curve for a worn cylinder-piston group, the lower one for a new one).
Способ осушествл ют следующим образом .The method is carried out as follows.
На крышках люков картера тепловозного двигател под каждым цилиндром устанавливают измерительные преобразователи давлени . Вывод т двигатель на режим 800-1000 и измер ют импульсы давлени газов, прорываюш,ихс из каждого цилиндра в моменты, соответсвующие положению поршн каждого цилиндра 30-40°Pressure gauge transducers are installed on the hatch covers of the diesel engine crankcase under each cylinder. Output the engine to 800-1000 mode and measure the pressure pulses of gases, breaking through, from each cylinder at times corresponding to the position of the piston of each cylinder 30-40 °
поворота коленчатого вала после н.м.т. Полученные величины импульсов давлени дл каждого цилиндра сравнивают с предельной величиной и оценивают техническое состо ние двигател .rotation of the crankshaft after n.m.t. The obtained pressure pulse values for each cylinder are compared with the limit value and the technical condition of the engine is evaluated.
