YaMZ 238M2 – Yaroslavldagi "Avtodiesel" motor zavodida ishlab chiqilgan va qurilgan dizel dvigatelining asosiy modeli. Ushbu dvigatel 8 silindrli, V shaklidagi, to'rt zarbali dizel dvigatellari qatoriga kiradi.
YaMZ 238M2 o'zining samaradorligi va ishonchliligi bilan mashhur bo'lgan juda keng tarqalgan dvigateldir. Ushbu dvigatel modeli juda ishonchli va yoqilg'i tejamkor, yetarlicha kuchli va yuqori momentga ega. Quvvat bloki hatto ekstremal ob-havo sharoitida ham ajoyib ishlashni namoyish etadi, -50°C dan +50°C gacha bo'lgan haroratga bardosh beradi. Mexanika ajoyib ta'mirlash qobiliyati bilan mashhur. Qurilmaning dizayni deyarli har qanday sharoitda ta'mirlash ishlarini bajarish imkonini beradi, chunki asosiy komponentlarga osongina kirish mumkin.
YaMZ-238M2 dizel dvigatellari va uning modifikatsiyalari Evro-0 standartlariga mos keladi va MAZ, KrAZ, Ural, MoAZ avtomobil markalariga, shuningdek, boshqa traktorlar va buldozerlarga, kombaynlarga, temir yo'l kranlariga, o'ziyurar roliklarga, qor tozalagichlarga, elektr stantsiyalariga, generator to'plamlariga va boshqalarga o'rnatiladi.
