SSCD180-1000-3800 180kW 1720Nm High Torque Measurement Accuracy Diesel Engine Electric Dynamometer Test Bench Description

The 180kW diesel engine electric dynamometer test bench is a specialized test system integrating electric dynamometer technology and intelligent control. It quantitatively evaluates engine performance through full-condition dynamic simulation and plays a core role in the research and development verification and production quality control of small and medium power diesel engines. ​
​
This test bench adopts a modular integrated design. Its core function is to simulate the actual operating load of the engine through an electric dynamometer, combined with a high-precision sensor array and an intelligent control system, to achieve real-time collection and analysis of power parameters (power/torque/rotational speed), economic indicators (fuel consumption), and emission data. The test bench needs to be equipped with professional vibration isolation foundations (natural frequency ≤6Hz) and sound barriers (noise reduction ≥42dB) to ensure the stability of the test environment and the accuracy of the data. ​
