"V" Line of Diesel Engines

"V" line of 4-cycle, V-type, 12-cylinder, liquid cooled, supercharged multifuel diesel engines is manufactured by Chelyabinsk tractor plant (ChTZ). This famous line of Soviet/Russian tank engines can be traced back to V-2 engine of the legendary T-34. The latest until recently, 840hp V-84MS drive-supercharged engine is installed on T-72B MBT and its later developments, T-72B(M) and T-90 MBTs.

This engine is very robust and unpretentious and operates reliably in adverse natural conditions including extremely cold and hot climes, dusty terrain and so on. However, it's power is somewhat small by today's standards. A new 1000hp V-92S2 engine that has arrived to replace it is the first engine of the line with a turbo-supercharger. This new engine, apparently installed on T-90 Vladimir MBTs and T-90 MBTs that are to be shipped to India, offers impressive specific power and specific fuel consumption characteristics.

In the end of January 2000 ChTZ announced that a new 1200hp diesel is ready for production. This engine reportedly weighs 1,070 kg, giving it an outstanding power to weight ratio. ChTZ promises to show this new diesel at UralExpoArms-2000 show.
