Main technical features
1. Easy operation
◆ Adjusting injection flow rate via a precision dia micrometer.
◆ Adjustable digital control touchscreen panel with easy-to-use interface.
◆ User-friendly software CNManager® provides an intuitive operation system.
◆ The injection advance, ignition delay and combustion signal curve, all information is provided on the display in real time with automated data recording, results calculation and report generation.
◆ Flexible report formats for built-in printer and export to LIMS or Excel.
◆ CNManager® guides the operator step by step easy to understand, and prompts service/maintenance when maintenance is needed.
2. Unique Technology and High Precision
◆ Fully learn from the latest development of the engine industry, the mechanical system of DW600T in the design, metal materials selection and processing technology is more sophisticated. It makes the accuracy, stability and reliability of the system to achieve the same level of imported equipment.
◆ The system delivers more consistent and reliable test results, accurate data recording, comprehensive report generation, and improved indication of critical operating variables.
◆ By measurement of cylinder displacement (equivalent to handwheel readings), obtain accurate compression ratio readings in real time.
◆ The control system has a dedicated modular controller to enhance reliability and make routine maintenance, service and troubleshooting simple and quick.
◆ The special combustion pickup DT60DS designed by industry standard, more stable and reliable and interchangeable.
◆ A cooling water circulation DW30CU and an independent temperature controller for injector are equipped in order to meet the standard requirements.
3. Safety & Environmental friendly
◆ All the mechanical moving parts have been protected limited interlock completely.
◆ An emergency stop button is installed on the operation panel for safety.
◆ Striking safety tips displayed clearly and completely on the digital control panel.
◆ Diesel engine with double balanced structure design, effectively reducing the vibration and noise.
◆ The systems equipped a muffler device to eliminate the noise effectively during operation to ensure that the laboratory quiet.
◆ The engine exhaust emissions to meet the discharge standards, and also to ensure the laboratory environment.
