Анализ работоспособности моторного масла вследствие загрязнения водой и охлаждающей жидкостью

Введение. В процессе эксплуатации тяжелонагруженной дизельной техники в районах с низкотемпературным климатом моторные масла подвергаются загрязнению со стороны охлаждающей жидкости и воды. Попадание данных веществ в смазочный материал приводит к ухудшению его показателей качества, что впоследствии влечет проблемы в узлах двигателя внутреннего сгорания.

Актуальность. Ухудшение значений показателей качества моторного масла напрямую связано с наличием воды и охлаждающей жидкости в нем. Не всегда возможно объективно отследить пути утечек данных загрязнителей, а это, в свою очередь, приводит к серьезным последствиям в виде износа соприкасающихся поверхностей деталей двигателя, коррозии. Важна также и оценка ресурса пакетов присадок смазочного материала вследствие разжижения его водой и антифризом.

Материалы и методы. В данной работе приведены результаты литературного обзора, направленного на изучение путей попадания охлаждающей жидкости и воды при эксплуатации дизельных двигателей, их влияния на физико-химические свойства моторных масел. Обозначены краткие сведения о составе охлаждающей жидкости.

Выводы. Попадание воды и охлаждающей жидкости в моторное масло влечет за собой увеличение кинематической вязкости смазочного материала, а также к образованию отложений на поверхностях пар трения двигателя. Помимо этого в картере двигателя возникают шарообразные соединения, представляющие собой совокупность разрушенных пакетов присадок и гликоля. Интервалы замены масла необходимо контролировать при повышенной интенсивности поступления воды и охлаждающей жидкости в моторное масло.

Рамки исследования/возможность. Такого вида исследование поможет определить причины проникновения воды и охлаждающей жидкости в картерное пространство, понять последствия использования загрязненного водой и охлаждающей жидкостью моторного масла.

Оригинальность/ценность. Проведенное исследование может являться основой для разработки рекомендаций по совершенствованию технического обслуживания двигателей внутреннего сгорания для предприятий, имеющих в своем распоряжении автомобили с дизельными двигателями с целью увеличения ресурса силовых агрегатов и сокращения эксплуатационных затрат.
