Brief introduction: Diesel cetane number determination machine in accordance with the latest version of ASTM D613, GB/T 386 "diesel cetane number determination method" requirements. It is suitable for the measurement of ignition delay characteristics of diesel fuel used in compressed-combustion engines. Automatically displays, saves test results, and prints test reports. The design, manufacture and inspection of the product shall comply with the following standards: ASTM D613 determination of cetane number in diesel oil ASTM D613 determination of cetane number in diesel oil ASTM D613 Features: The fuel flow adopts the photoelectric automatic measurement system and the computer adjustment control, avoids the manual measurement error. Real-time display of the working curve, timely understand the time point of the instrument fire. Automatic control of injection Angle, imported electric control pump and injection nozzle. Variable compression ratio plug adjustment handwheel and imported instrument structure consistent, universal extremely high. The use of laser ranging automatic reading, directly get the test results, without manual table calculation. Air intake configuration: large capacity air purification device. Exhaust configuration: the instrument is equipped with a muffler to effectively eliminate noise during operation. Lubrication system: equipped with lubricating oil auxiliary preheating, effectively shorten the preheating time. Oil inlet system: 3 parallel oil tanks and 1 flow detection tube. Safety system: set emergency stop function to realize emergency protection under abnormal state. Intelligent diagnosis of instrument working conditions, control technology, data collection, automatic calculation, Automatic control, automatic table lookup, printing and prompt functions. Real-time display and recording of instrument conditions, real-time monitoring of cooling water temperature, inlet temperature, nozzle temperature, Oil temperature, fuel temperature, motor power and other working conditions. Engine operating pressure negative pressure sensor, real-time display. Engine power indicator, digital screen display. Automatic recording of startup and test cumulative time.
