Diesel Cetane Number Tester

Category:

Building on years of research and development in bench‑type testing machines, Jingzhou Chuangbo has successfully designed the JZCB‑386 diesel cetane number tester, fully compliant with ASTM D613‑23 and GB/T 386‑2021 standards. Its functionality and performance meet or exceed the requirements of these standards. The instrument features a standard single‑cylinder, four‑stroke, variable compression ratio, indirect injection diesel engine. By precisely controlling fuel flow rate, injection timing, and compression ratio, it compares the test sample diesel with a reference fuel to determine the ignition delay period of the diesel under test. This device achieves stability and reliability comparable to similar imported products, while significantly enhancing ease of operation, making cetane number testing for diesel much less cumbersome. It fully complies with GB/T 386‑2021 and ASTM D613 standards. The core component is a standard single‑cylinder, four‑stroke, variable compression ratio, indirect injection diesel engine. - Fully automated operation: once parameters are set, the system automatically performs the oil evaluation and generates test results (which can be printed). - Adheres strictly to the standards, employing a high‑performance fuel injection pump and single‑hole injectors; both the injection opening pressure and spray pattern satisfy standard requirements. - A specialized combustion sensor, designed according to industrial standards, ensures enhanced stability and reliability. - Equipped with precision adjustment knobs for regulating injection speed, enabling compliance with specified standards. ◆ Automatic, high‑precision measurement of cylinder displacement (equivalent to manual dial readings), providing real‑time, accurate compression ratio data. At the conclusion of the test procedure, the cetane number of the sample can be directly read, with test results conveniently output via the panel printer. - The control system utilizes a modular, dedicated controller, improving reliability while simplifying routine maintenance, servicing, and troubleshooting. - The instrument features an operator console that greatly facilitates handling; its software interface offers high integration, presenting all real‑time status information clearly at a glance, including real‑time trends of combustion signals, along with timely and clear operational prompts. - The software employs a guided‑operation design, walking users through each step of the standard procedure in a straightforward, easy‑to‑understand manner. - It records startup and cumulative operating times, issuing automatic reminders for scheduled maintenance. - The instrument is equipped with an independent circulating cooling water system and individually controlled temperature regulation for the injectors, ensuring strict adherence to standard requirements.
