How Does a Diesel Generator Exhaust System Work?
The main function of a diesel generator exhaust system is to safely remove harmful gases produced during operation. As the engine burns fuel, it creates exhaust gases that must be vented out of the generator and away from people and equipment. The exhaust system consists of several parts, including the exhaust manifold, muffler, and exhaust pipe.

What is exhaust stack & air intake design?
Exhaust Stack and Air Intake Design Strategies........................................................................... air enters a building through its air intake to provide ventilation air to building occupants. Likewise, building ex-haust systems remove air from a building and expel the contaminants to the atmosphere.
Do I need a room between my generators?
If you never do anything you never have problems. Yes, you will need to allow for plenty of room between the generators for both ventilation and maintenance equipment. There are some other things you may want to take into account. 1. Are you using an exhaust system or do you plan on using louvers to allow for airflow through the room?
