Non-integral fuel emission control device and method

Номер: CN116398329A
Принадлежит:

The invention provides a non-integral fuel oil emission control device and method. The non-integral fuel oil emission control device comprises a first shaft body, a second shaft body and a shell. The first shaft body and the second shaft body are both located on the inner side of the shell. A plurality of connecting channels are formed in the inner side of the shell, and a plurality of through holes are formed in the first shaft body and the second shaft body; each of the first shaft body and the second shaft body has a default position state and a working position state; in any position state, at least one through hole of the first shaft body is communicated with one through hole of the second shaft body, and the two through holes are communicated with the connecting channel. The method has the beneficial effect that the emission of hydrocarbon can be reduced by converting different working conditions into different fuel oil emission modes.
