Main Technical Features:

1.The host is a standard single-cylinder engine with the variable compression ratio, equipping with carburetor, air drier (Hereafter referred to ice tower), ignition system, signal sensor and other parts. Under the control of the computer system, it has the collection, calculation, display, save and print test results functions.
2.The instrument has Motor method and Research method standard test methods.
3. Combined belt pulley is used, to facilitate to exchange between two test methods.
4. A new mixed heater is used, to facilitate to exchange between two test methods.
5. Compression ratio can be adjusted automatically or inching adjusted. The cylinder body has the limit protection for the lifting operation.
6. Hall ignition way is used, to ensure the accuracy and stability of the ignition, extending the life of the igniter.
7. Ignition advance angle is adjusted automatically.
8. Preset octane number - compression ratio work curve is embedded, with automatic table loop-up.
9. A good engine working condition ensures that the interpolation method and compression ratio method can comply with the national standards.
10. A environmental air pressure automatic compensation function is built in.
11. Touch screen is used, to display the operation tips in real time.
12. Pressure inside the crankcase is monitored.
13. With the oil preheating function, preheat time is reduced.
14. A new four-cavity carburetor is used, to meet the light component oil test requirements. (Optional)
15. The optimum liquid level can be automatically found, to reduce the human errors, easy to operate. (Optional)
