The article designs and manufactures an engine mounting test stand with a structure that can not only mount a single test engine but also mount many different types of engines with an engine support structure that can move along the X, Y, Z axes and rotate around the Z axis, making it very flexible and easy to mount and align the engine connected to the MP100S dynamometer system. Manufacturing and assembling a complete engine mounting test stand that can be linked to the MP100S dynamometer system ensures technical requirements, safe operation, and testing to measure the number of revolutions n (rpm), torque Mx (N·m), and power P (kW) of the engine when operating at no load and with load. The results of the paper can be used as reference data in calculating the design and manufacturing of the engine mounting test stand to measure the number of revolutions, torque and power of the engine, Turbocharger blade efficiency, exhaust gas pressure, fuel consumption corresponding to each engine operating mode.
