Testing Diesel Cetane Number Instrument Testing Diesel Cetane Number Instrument
 The core of the diesel cetane number analyzer simulates the combustion process of diesel fuel in an engine, calculating the cetane number by detecting combustion characteristics. During operation, a small amount of diesel sample is injected into a sealed simulated combustion chamber, and the chamber temperature is raised to the typical temperature required for diesel self-ignition (usually 350-400°C) via a heating device, while maintaining the chamber pressure within the range of engine compression stroke pressure (approximately 3-5 MPa). Once the sample reaches self-ignition conditions, the instrument uses high-precision sensors to record the time interval from "reaching self-ignition temperature" to "start of combustion" in real-time—this is the "ignition delay period," a key indicator, as higher diesel cetane numbers result in better self-ignition and shorter ignition delay periods. Subsequently, the instrument compares the measured ignition delay period with a pre-stored database of "standard fuel (mixtures of n-hexadecane and α-methylnaphthalene with known cetane numbers) ignition delay periods," and calculates the sample's cetane number using built-in algorithms.

Utilizes the analytical principles of insulating permeability and electromagnetic induction charge characteristics for gasoline octane number and diesel cetane number.

   The instrument is highly sensitive, capable of detecting minute changes in dielectric parameters, and features atmospheric pressure correction.

    Provides more comprehensive and accurate measurement of various data for petroleum products.

    Capable of measuring various gasoline types containing additives.

    Measures diesel cetane number, diesel type, and condensation temperature.

    Simultaneously displays RON, MON, and Anti-Knock Index (AKI). AKI = (RON + MON)/2.

    A powerful processing chip enables fast and accurate data processing, compatible with Windows systems.

    Features temperature correction and low operating costs.

    Simple and easy to operate, compact, portable, with vibration-resistant, solvent-resistant, and sealed casing.

    Four-row backlit LCD display, suitable for low-temperature environments, power indicator, and external low-voltage power supply.
