  1. Seeing that T-34 production had already started, can I presume that this is part of the development program to increase general reliability of the engine?

    1. Yes, requirement was 250 hours, but the current engine had a warranty period of only 100 hours, so they decided to go ahead with tank production anyway while the engine designers ironed out the kinks. The T-34 changed quite a bit between mid 1940 and early 1941, and the planned changes were even more extensive.
