What about barbecue smoke?

Barbecue fume can be treated, such as a barbecue oven with fume purifier, but it will not be used for a long time.

If you are stationary, you can add an oil fume purifier to the pipeline, which is better than the whole car.

If you just want to smoke, instead of purifying the oil fume, you just add a smoke exhaust pipe directly. .

If you don't know how to choose and specifications, you can ask me again.
