Just guessing the Chinese version. I think there is no official terms since the meaning is more of a descriptive nature instead of fixed names.

Cert fuel refers to gasoline used in motor vehicles, as in the more developed countries, there is a lot of pollution control regulations. Ingredients like lead, benzene and MTBE are being phased out. Sulfur level is being drastically reduced as high sulfur content in gasoline clogs up catalytic converters that clean up vehicle emissions from the engine.
I think the current fuel standards are:
Europe: Euro 3.
HK: Euro 3.
Singapore: Euro 2.
China: Euro 1.

As for house fuels used for heating or cooking purposes like kerosene, charcoal, town gas, etc, I don't think there are pollution standards involved.
IF this is the meaning intended then 幒撪擱椏. But I suspect 'house fuel' here means 'fuel formulated in-house' without fulfilling standard requirements for in-company(in-house) use of testing purposes.

The Euro standards are actually vehicle emission standards. But for the advanced pollution control devices in vehicles to work properly, the gasoline has to be of a certain standard with regard to additives and sulfur level.

There are many types of approaches taken; in HK I think they started out by giving tax incentives to cleaner fuel in year 2000 while in Singapore, it is blanket legislation.

In USA, they are various standards and these may vary in different states. The toughest state is California.
