75kW Gasoline Engine Dynamometer Test Bench with 0.05%FS Accuracy

The 75kW gasoline engine electric dynamometer test bench system converts the mechanical energy output by the engine into electrical energy for power measurement. It can simulate various operating conditions and provide accurate data for engine performance evaluation. This unique working method establishes its core position in engine performance evaluation.

• GB/T 18297-2024 "Performance test code for road vehicle engines": Applicable to M and N category automotive gasoline and diesel engines (excluding free piston engines, other fuel engines may refer to this standard).
• GB/T 19055-2024 "Reliability test methods for motor vehicle engines": Applicable to M and N category automotive reciprocating and rotary engines (excluding free piston engines). This standard specifies complete engine bench reliability testing and assessment methods.

The 75kW gasoline engine electric dynamometer test bench system mainly consists of the following components:

• Electric dynamometer: Responsible for engine loading and dragging, consisting of an AC motor, a torque flange (German HBM T40B series, used for torque measurement) and a mounting bracket.
• ABB ACS880 variable frequency inverter system: Controls the electric dynamometer, can load the engine in the forward direction and drag the engine in the reverse direction.
• XLE-1000 measurement and control system and software: Carries out overall control of the test bench, communicates with the frequency conversion system via the bus to set/control operating conditions.
• Data acquisition system: Equipped with suitable temperature/pressure sensors and acquisition modules.
• Throttle actuator: Adjusts various throttle openings, has large torque, fast response, and good dynamic performance.
• Transient fuel consumption meter and fuel boost and pressure regulating device: The fuel consumption meter accurately measures the fuel consumption of diesel/gasoline engines.
• Coolant temperature control device: Controls the engine coolant temperature with high precision and fast response.

• Accurate dynamometer torque measurement: Equipped with a high-precision torque sensor (e.g., up to 0.05% FS), it can accurately capture the torque output of the engine at different speeds and loads.
• Energy recovery and significant energy-saving effect: Through the variable frequency inverter system, the electric energy generated by the dynamometer is fed back to the power grid, reducing energy waste.

Can be customized

• Automobile engine R&D and testing: simulate idling, acceleration and other operating conditions to test power output, fuel economy and emission performance.
• Ship power system testing: Simulates complex sailing conditions to verify engine performance under different loads and speeds.
• Generator performance test: Test the power generation performance of gasoline generator sets during load start-up and load sudden changes.
• General power equipment performance evaluation: used for garden machinery, small construction machinery and other equipment to test engine performance consistency.

From October 24th to 26th, 2024, the Russian International Testing and Control Exhibition was successfully held at the Moscow Klokus International Convention and Exhibition Center. The exhibition is hosted by the well-known Russian exhibition company MVK and is an annual international professional exhibition on testing and control.

As the largest and most influential testing and control equipment exhibition in Russia, it has received strong support from official institutions such as the Russian Federation Ministry of Defense, Ministry of Industry and Trade, State Duma Defense Committee, Federal Technical Regulations and Metrology Bureau, and State Economic Development Bureau.
