Abstract Exhaust emission index is the key item of explosion-proof diesel engine inspection. In this paper, the international emission standards and domestic standards are compared and analyzed, and the differences between China and foreign emission standards are found. The test results of imported Caterpillar c9 explosion-proof diesel engine under two different emission standards in China and Australia are studied. The experimental results show that the same diesel engine in China and Australia on their respective laboratory equipment measured results are not much different, proved that China 's current test methods and means of implementation of explosion-proof diesel engine emission performance has reached the international advanced level.
