The Kharkiv model V-2 (Russian: В-2) was a Soviet diesel tank V-12 engine, the V angle at 60°, with dual overhead camshafts per bank, four valves per cylinder opened by bucket-style followers and direct fuel injection, features found on modern high-performance diesel engines. Designed at the Kharkiv Locomotive Factory by Konstantin Chelpan and his team, it is found in the BT-7M (BT-8), T-34, KV, IS and IS-10 (T-10) tanks, and by extension, the vehicles based on them, such as the SU-85 and SU-100 tank destroyers based on the T-34 and the ISU-122 and ISU-152 self-propelled guns based on the IS-2. Throughout its production life, output ranged from roughly 450-700 hp.
