The most interesting thing in the tank T-64 is its engine, which has nickname suitcase. The construction is very unusual and the information in our country is sparse.
5DTF is a diesel multi-fuel, two-stroke (!), Supercharged flat five-cylinder with counter-rotating pistons (!), Which means that there are ten pistons on two crankshafts.
TTD Number of cylinders -5 Cylinder volume-13.5 l Drilling-120mm Stroke of one piston-120mm Power-700k/2800rpm Liter output-52k/l Max. ot.-3000 Weight-1040kg Length.1413mm Width-955mm Height-581mm
Activity-Tact first: The two pistons (in one cylinder) go apart from each other under the action of the exhaust gas pressure. rinsing. Second stroke: The two pistons move towards each other and compress the air, which heats up sharply. Just before the top dead center, fuel is injected, which is taken in, expands and the first stroke occurs.
The biggest advantages are the high liter output and small dimensions. However, this is misleading because the weight is the same as for the V-series engines with a volume of 38.88 l for the other points. Disadvantages include high failure rates, poor winter starting, high temperature loads. This is likely to be eliminated because newer and larger versions of the 6TD engine are offered in the new T-72 and T-84 tanks. Personally, I think that the tax on dimensions is too high. Although I do not need a cylinder head, but it is not complicated for a two-stroke, but I need two crankshafts, which complicates installation, lubrication, etc. Thanks to trying to overheat saved by a smaller engine or a more powerful radiator fan that takes more of the engine's power.
