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.

Diesel Engine Electric Dynamometer Test Bench Typical Application Scenarios
- Research and development testing
Power performance optimization: Complete the mapping of the
full-speed range external characteristic curve (torque fluctuation
≤1.2%), and optimize the fuel injection pressure and turbocharging
to match the parameters.
Emission compliance verification: Support for the National VI b
emission certification test (NOx emission control accuracy ±2.5%),

after-treatment system
Electronic control system calibration: Test the low-temperature
start-up fuel injection strategy and rail pressure control logic
through the reverse drag function (electric mode power ≥40kW)
Durability performance test: Perform 1000 hours of intensive
durability cycles (load fluctuation ≤3.5%) and monitor cylinder
liner wear ≤0.025mm
Environmental adaptability test: Simulate the start-up performance
and stable operation capability in high altitude (4,200 meters
above sea level, with an intake oxygen concentration of 11.8%) and
extremely cold conditions (-30℃)
- Production quality control
Off-line full inspection process: 6-minute rapid performance scan
(covering 14 key indicators), power consistency controlled within
±1.8%
Process change validation: Performance comparison after component
replacement (e.g. Fuel consumption deviation after fuel injector
replacement ≤0.7%, emission index fluctuation ≤3%)
The test bench, through the deep integration of electric power
measurement technology and intelligent control, achieves full
process test coverage from R&D design to mass production
quality control, providing precise quantitative data support for
the technical upgrade and quality control of 180kW diesel engines.
