Ochiq kon ishlari sharoitida ichki yonuv dvigatellari yuqori konsentratsiyadagi abraziv chang muhitida ishlaydi, bu esa silindr-porshen guruhining jadal yedirilishiga, dvigatel quvvatining pasayishiga, yoqilg‘i sarfining ortishiga hamda dvigatel resursining qisqarishiga olib keladi. Mazkur maqolada kirish havosi tarkibidagi chang zarrachalarining dispers tarkibi va konsentratsiyasining dvigatelning asosiy birikmalari tribologik holatiga, moy plyonkasi parametrlariga hamda kuch qurilmasining ekspluatatsion ko‘rsatkichlariga ta’sir komplekslari tahlil qilingan. Tadqiqot natijalariga ko‘ra, o‘lchami 5–20 mkm bo‘lgan zarrachalar eng katta xavf tug‘dirib, tezlashgan abraziv yedirilish hamda yonish kamerasining germetikligi yomonlashishiga sabab bo‘lishi aniqlangan. Nazariy va ekspluatatsion ma’lumotlar asosida kirish havosini tozalash samaradorligini oshirish zarurati ilmiy jihatdan asoslab berilgan.
Ishda ko‘p bosqichli kombinatsiyalashgan havo filtri konstruksiyasi ishlab chiqilib taklif etilgan bo‘lib, u multitsiklonli dastlabki tozalash, ikki bosqichli elektrostatik ajratish hamda standart filtrlovchi element orqali yakuniy tozalash jarayonlarini o‘z ichiga oladi. Taklif etilgan tizim 0,1–20 mkm o‘lchamdagi zarrachalarni past aero-dinamik qarshilik sharoitida ushlab qolishni ta’minlab, umumiy tozalash samaradorligini 95% gacha oshiradi. Ishlab chiqilgan tizimni qo‘llash silindr-porshen guruhining yedirilish jadalligini kamaytirish, asosiy filtr va dvigatel resursini oshirish, yoqilg‘ining solishtirma sarfini kamaytirish hamda yuqori changlangan sharoitlarda kon mashi-nalarining ekspluatatsion ishonchliligini oshirish imkonini beradi.
