Firstly, the octane number tester body 12 is started, an ignition switch of the octane number tester is started, a fuel system is also enabled to work, namely, a control switch of the fuel pump 2 is started, fuel is arranged in an oil way, oil (generally gasoline is used in the heat engine process) sprayed out by the fuel injector 5 enters a combustion chamber 11 of the octane number tester to burn after the air inlet pipe is completely atomized, and the octane number tester body 12 is preheated for about 30 minutes.

The optimal oil-gas equivalent ratio is automatically found through the control software of the electronic unit, so that the maximum knocking intensity can be found, and the octane number of the fuel can be accurately measured. Exhaust gas generated after the fuel is burned in the combustion chamber 11 of the octane number measuring machine flows to the exhaust gas aftertreatment device 14 through the exhaust pipe 13; the exhaust gas is then passed through a muffler 15 and discharged to the atmosphere.
If only the octane number of the gaseous fuel is to be measured, it is also necessary to operate according to the above thermo-mechanical procedure. After each parameter of the gaseous fuel supply system and the air intake system reaches the test condition of octane number, namely after the heat engine is finished, each control unit of the liquid fuel supply system is closed.

Exhaust gas generated after combustion of fuel in the combustion chamber 11 of the octane number measuring machine flows to the exhaust gas aftertreatment device 14 through the exhaust pipe 13. The exhaust gas then passes through the muffler 15 and is discharged to the atmosphere.
