Ushbu maqolada O‘zbekiston Respublikasi iqlim sharoitida motor moylari sifat ko‘rsatkichlarining chegaraviy qiymatlarini ishlab chiqishga doir masalalar o‘rganilgan. Dvigatelda motor moyi sifati nafaqat dvigatelning asosiy mezonlari, resursi va texnik holati, balki motor moylari sarfi hamda almashtirish muddatlariga ham katta ta’sir ko‘rsatadi. Moylarni almashtirish muddatlari esa uning ekspluatatsiya sharoitida chegaraviy qiymatlari miqdoriga bog‘liq. Motor moylari dvigatel konstruksiyasi uchun eng zarur ashyo bo‘lib, moylash materiallari sifati yonilg‘i tejamkorligi va dvigatelning uzoq muddat ishlashiga ta’sir qiladi. Neft mahsulotlari zaxirasining kamligi va narxining qimmatligi ulardan tejamli foydalanishni talab etadi. Motor moylari sifat ko‘rsatkichlarining o‘zgarishi, transport vositalari samaradorligiga salbiy ta’sirini o‘rganish hamda ushbu ta’sirlarni iqlim sharoitidan kelib chiqqan holda kamaytirish dolzarb muammodir. Tadqiqot predmeti sifatida motor moylarining fizik-kimyoviy xossalari va ekspluatatsion ko‘rsatkichlari kabi omillar olingan. Ekspluatatsiya sharoitida motor moylari sifat ko‘rsatkichlarining chegaraviy qiymatlari bo‘yicha zarur adabiyotlarni tahlil qilish, motor moylari assortimenti hamda motor moylarini ekspluatatsiya sharoitida sifat ko‘rsatkichlari chegaraviy qiymatlarini o‘rganish tadqiqotning asosiy maqsadidir. Laboratoriya sharoitida eksperimental tadqiqotlar o‘tkazilib, ekspluatatsiya sharoitida motor moylari sifat ko‘rsatkichlarini baholash mezonlari tanlab olindi. Shuningdek, motor moylari sifat ko‘rsatkichlarining chegaraviy qiymatlari ishlab chiqildi.

В данной статье рассмотрены вопросы разработки предельных значений показателей качества моторных масел в климатических условиях Республики Узбекистан. Качество моторного масла оказывает большое влияние не только на основные критерии, ресурс и техническое состояние двигателя, но и на расход и сроки замены моторного масла. Сроки замены масла зависят от величины его предельных значений в условиях эксплуатации. Моторные масла являются необходимым элементом конструкции двигателя, а качество смазочных материалов влияет на экономию топлива и долговечность двигателя. Небольшие запасы и дороговизна нефтепродуктов требуют их экономного использования. Актуальной проблемой является изучение изменения качественных показателей моторных масел, их негативного влияния на эффективность эксплуатации транспортных средств, а также смягчение этих воздействий, обусловленных климатическими условиями. В качестве предмета исследования были взяты такие факторы, как физикохимические свойства и эксплуатационные показатели моторных масел. Основными целями исследования является анализ необходимой литературы касательно предельных значений показателей качества моторных масел в условиях эксплуатации и ассортимента моторных масел. Проведены экспериментальные исследования в лабораторных условиях, выбраны критерии оценки качественных показателей моторных масел в условиях эксплуатации. Также разработаны предельные значения показателей качества моторных масел.

The article discusses the issues of development of limit values of quality indicators of motor oils in climatic conditions of the Republic of Uzbekistan. The quality of engine oil greatly affects basic criteria, resource and technical condition of the engine, as well as - consumption and timing of the engine oil change. Timing of oil replacement depends on the value of its limit values in operating conditions. Engine oils are an essential element of the engine design, and the quality of lubricants affects fuel economy and engine durability. Small stocks and high cost of oil products require their efficient use. The research relevance is explained by the need to study changes in qualitative indicators of motor oils, their negative effect on the efficiency of operation of vehicles, as well as mitigation of these effects caused by climatic conditions. Factors including physical and chemical properties and performance indicators of motor oils, were taken as the research subject. The main objectives of the study include review of the relevant literature concerning the limit values of quality indicators of motor oils in operating conditions and the range of motor oils. Experimental studies in laboratory conditions have been made, criteria for assessing the quality indicators of motor oils under operating conditions - selected. And limit values of quality indicators of motor oils have also been developed.
