Engine Room Ventilation

[cabalen]

What are the requirements in Engine room ventilation? Thanks.

Combustion air + excess air + cooling air = total airflow

You can get all this from the engine maker.

If you are talking about a generator with a remote rad, you could be changing the air every minute in the room.

As others have mentioned get the combustion air requirement, the heat off of the block, the heat off of the alternator and the heat picked up through insulated exhaust to determine your air flow.

If it is a gen with a rad and a cowling outside for the exhaust, the air moving for the rad is going to be limited to 0.5" static per NFPA110,

Besides combustion and the rad air, you will most likely need some more air flowing.
