Diesel engine V-2
The V-2 engine was installed before the war on Soviet BT-7M light tanks, T-34 medium tanks, KV-1 and KV-2 heavy tanks, as well as on the Voroshilovets heavy tracked artillery tractor. During the war it was installed on T-34 medium tanks, heavy KV and IS tanks, as well as on cars derived from them. In the post-war years this engine was modernized and its direct descendants are modern tank engines.
