Description of the test stand for investigation of the integrated powertrain (powerpack) for armoured modular vehicle (AMV), disassembled from vehicle, is presented in this paper. The powerpack unit consist of a diesel engine, a gearbox and a cooling unit with a hydraulic fan drive. The stand is equipped with measuring devices for torque measure, fuel consumption, exhaust smoke and exhaust gas components emission analysers. The powerpack has been loaded by a hydraulic dynamometer of power range up to 1250 kW. It is dynabar water dynamometer with high dynamics of load changes. For control the motor and drive, system the original control panels from the vehicle was used. The original start-up unit, mid fuel tank and air filters were used too. Research on the powerpack unit was made in the steady state versus the engine load and speed. The parameters of the engine and exhaust components were measured and compared with the catalogue values. Two modes of engine work were compared – economic and dynamic modes. Those differences between two modes are result of maximum fuel consumption decreasing. The parameters of engine work were comparable in middle and low range of engine load. On the stand investigation in transient states during free engine acceleration were made. It was found that additional load of engine is too high and this problem should be clarified.
