At present, the modification technology of domestic dual-fuel vehicles is still relatively mature, and the modification plants that sell kits are also blooming everywhere. Baidu can do it. Relatively speaking, there is little technology to modify the diesel engine of large trucks. There are only a few technical forces that can modify diesel engines online. As for the technical reliability, it has yet to be verified. I need you to consult and compare with them one by one after Baidu comes out.

Departments that need to pass the qualification examination to operate CNG gas automobile refitting plants.

The term "gas vehicles" as mentioned in these Provisions refers to gas or dual-fuel vehicles that are converted from gasoline (diesel) vehicles to compressed natural gas or liquefied petroleum gas as fuel.
