Hengaode Instrument meets the requirementsASTM D2699Operating principle of octane rating tester for automotive gasoline

Mainly based on measuring the dielectric properties of gasoline or diesel (such as dielectric constant or insulation permeability), and comparing them with known standard data models in the built-in database, the octane number or cetane number can be quickly calculated.‌

The core components of the instrument include sensors, measurement systems, and data processing units, among which sensors are highly sensitive to electromagnetic induction or spectral signals of oil products and can detect small parameter changes.‌

The operation process usually includes the following steps: first, prepare the equipment, check the status of the instrument, clean the accessories, and ensure that the power supply is normal;‌

Next, prepare a sample and take an appropriate amount of uncontaminated oil (such as10–20 mLGasoline, filter impurities if necessary;‌

Then set up the instrument according to the testing standards (such as research methods)RONOr motor methodMON）Adjust temperature, pressure, and speed parameters, and calibrate the instrument using standard samples;‌

Then perform the measurement, inject the sample into the sensor or combustion chamber, and the instrument automatically adjusts the compression ratio or scans the dielectric parameters, displaying the results in real time (response time can be as short as1Seconds);‌

Finally, perform cleaning and maintenance, clean the sensor with petroleum ether, and calibrate regularly to ensure accuracy.‌

The instrument design emphasizes portability and automation, such as using embedded computer systems to interact with infrared touch screens, supporting the detection of various oil products (including ethanol gasoline, biodiesel), and complying withASTMWaiting for international standards.‌

Pay attention to ventilation safety, wear protective equipment, and avoid splashing high-temperature oil during operation.‌
