EOL4000 - Engine factory online test system - Key features

01 Functional Modularization

All the platforms are modularized by function, which is concentrated in one test system in the form of module combination.

02 Advanced means of measurement

Advanced measurement and control system is adopted, including input speed and torque, etc. High sampling rate is adopted to sample the torque speed, which meets the requirements of high precision and rapid response of the test system. Besides, transient data and eigenvalue data are provided to facilitate the software to conduct comprehensive analysis of the test process data in the later stage.

The test items are complete

According to the test requirements stipulated by national standards, the test items can be increased or decreased according to the configuration module, which can meet the test items for various types of tests

Load of dynamometer

Using power dynamometer/eddy current dynamometer as subjects of engine load, change the traditional way of load, improve the system of dynamic measurement of torque and rotational speed range and accuracy, improve load (is/reverse, the drag power dynamometer ()), and shorten the response time of load, which can realize arbitrary load curve of load, high real time simulation engine operating conditions.

Temperature control system equipment

Indirect heat transfer mode is adopted to keep the coolant, oil and turbocharger in the optimal working mode when the engine is running, which ensures the guarantee measures for the engine to do various tests.

06 Humanized design

It adopts professional engine test bench, which has the function of quick alignment in engine tooling and easy loading and unloading, and can adapt to installation of different tested parts. The system operation is recommended to adopt the control mode of cabinet + computer desk, which can complete all the test operation layout.

Customized test software

The engine test system test software developed by Sichuan Chengbang software research and development team classifies the software interface and process according to the national standard test items to reduce the repetition of tests and greatly improve the work efficiency of test personnel. It also has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualification determination, report export and so on.
