Brief introduction: DW600T is a diesel cetane number measuring machine launched by us according to ASTM D613 and GR/T 386 standard latest version, with full independent intellectual property rights. Its main body is a standard single-cylinder, four-stroke, variable compression ratio, indirect injection diesel engine, under the condition of controlling fuel flow rate, injection time and compression ratio, the diesel fuel to be tested is compared with the standard fuel, and the measured value of ignition lag time of diesel fuel is obtained. DW600T typical test range is 30 ~ 65. The stability and reliability of the instrument, the accuracy and stability of the results can reach the level of similar imported products, and at the same time improve the convenience of test operation. Functional features: 1. Using precision rotary encoder to measure the running phase of the engine, accurate and reliable; 2. The sensitivity and frequency response of the combustion sensor DT60DS have reached the level of imported products; 3. The laser module can measure the precise compression ratio reading (handwheel reading) in real time. The test results can be read directly after the end of the test steps to improve the automation level; 4. Precise operation knob is set to adjust the oil injection speed to meet the standard requirements; 5. Equipped with lubricating oil preheating module, the preheating time is controlled within 30 minutes, and the lubricating oil is divided into coarse and fine filtration; 6. DW30CU low-power circulating cooling water system is configured, and the fuel injector is independently equipped with temperature control device; 7. The control system adopts modular controller to enhance reliability and make daily maintenance, maintenance and fault treatment easy and convenient; 8. All kinds of real-time status monitoring information on the operation interface are clear at a glance. The design of operation buttons guided by the test steps is beautiful and easy to learn. 9. The interface displays the trend curve of fuel injection advance Angle and ignition lag period in real time, and automatically records the startup time and cumulative running time.
