  1 ET4000—Engine Measurement and Control System (Container Type)—Main Features

  01 Functional modularity

  All the benches are built using functional modularity, and are combined into one test system in the form of a combination of modules. Customers can add or remove test modules according to different test objects.

  02 Container

  The modular structure of the container can be designed according to the needs of customers. The first floor is divided into a rack room and a control room. The second floor is an equipment room, air supply and exhaust system, and smoke exhaust system. The container is equipped with sound insulation measures, lifting devices, water, electricity, gas, oil and other pipeline systems. All the bench equipment is modularized and put into the container to complete the entire bench test.

  03 Advanced measurement methods

  Adopt advanced measurement and control system, including input speed, torque and other tests. Torque speed sampling adopts high sampling rate, which meets the requirements of high precision and fast response of the test system, and provides transient data and characteristic value data, which is convenient for the software to perform the test process data later Comprehensive analysis.

  04 Complete test items

  According to the test requirements specified in the national standard, test items can be added or removed according to the configuration module, which can meet the test items for various types of tests

  05 Dynamometer load

  Using electric dynamometer or eddy dynamometer to load can realize the loading of any load curve and highly simulate the real-time operating conditions of the engine.

  06Temperature control system equipment

  The use of indirect heat exchange mode makes the engine running with coolant, oil, and turbocharger in the optimal working mode, which ensures that the engine is doing various tests.
