Product Description
Gasoline Octane Number Tester (Motor Method)
Product model: JF503
Product Introduction
It is used to determine the anti-knock performance of gasoline for automobiles and ignition type aero-engines, in line with ASTM D2699, D2700 standards, using the standard reference fuel and the test sample to compare the same test method. The stability and reliability of the instrument, as well as the convenience of the test operation and the accuracy of the results can all reach the advanced level at home and abroad.

Main Feature
1. It meets the requirements of the research method and the motor method. The two working conditions of the motor method and the research method can be switched quickly, and the operation is simple and easy;
2. Adopt standard single-cylinder CFR standard engine
3. The motor method research method is interchangeable, and two sets of data of gasoline octane number and anti-knock index can be obtained
4. The whole machine adopts a structured design, and the control system adopts a modular controller, which enhances reliability and makes daily maintenance, maintenance and troubleshooting easy and convenient;
5. The compression ratio is measured by a precision displacement sensor, and the measurement accuracy is high;
6. The knock sensor is designed with high sensitivity and high reliability, and the signal acquisition system has good adaptability;
7. Using the software digital knock meter, the adjustment of the knock signal is more convenient;
8. The ignition control is realized by using the precise rotary encoder technology, and the ignition angle adjustment does not require mechanical adjustment;
9. The ambient air pressure software compensation module is prepared to realize automatic compensation during the test process, and the relationship between octane number and compression ratio is built-in;
10. Equipped with large-capacity air conditioning unit with two-stage temperature control function, the temperature control adopts adaptive PID control, and the temperature control accuracy is high, which can provide dust-free, dry and constant temperature gas that meets the standard for testing;
11. Equipped with lubricating oil preheating module, the preheating time is controlled within 30min, and the lubricating oil is filtered in two stages: coarse and fine;
12. Equipped with ADDITION low-power and high-efficiency circulating cooling device, the power consumption of the device is less than 0.5kW;
13. Using a fixed touch screen console, the test software ADDITION has a high degree of integration of the operation interface, various real-time status monitoring information is clear at a glance, and the test step-guided operation button design is adopted;
14. ADDITION displays the 100s knock intensity trend curve in real time, and automatically records the startup time and accumulated running time.Diesel fatty acid methyl ester content analyzer (infrared spectroscopy), it has the characteristics of convenient installation, simple use, convenient maintenance, etc.
15.It is widely used in the qualitative and quantitative analysis of organic compounds, inorganic compounds, polymers, etc. Diffuse reflection, ATR attenuated total reflection, non-contact external reflection, etc., with excellent performance.
