Generator Engine Room Ventilation
Ventilation air inlets and outlets should be positioned to prevent pockets of stagnant or recirculating air, especially in the vicinity of the generator air inlet.

When ever possible, face the generator air inlet openings away from the wind. The wind can prevent the air intake louver from opening on start up. The air inlet must be capable of moving enough air through the room to provide the correct minimum CFM (cubic feet per minute) cooling for generator as specified by the generator's manufacturer.
Find the area of the generator's inlet air duct, by multiplying the air duct height by its width. Divide the inlet air duct area by the percentage of free air inlet area for the particular screening or expanded metal to be used. The result is the required size of the air inlet opening in the building.
The diesel generator air intake and exhaust system (DGAIES) provides the diesel engine with combustion air from the outside. The combustion air passes through a filter and silencer before being compressed by a turbocharger and cooled by the coolant system before entering the individual cylinders for combustion.
Louvers, screening, expanded metal and other materials used to cover air openings are a restriction to air flow. This restriction must be compensated for by making the air opening size proportionally larger. When possible, position the engine end of air cooled generators in line with the air inlet per the manufacturer's recommendation.
Ventilation air inlets and outlets should be positioned to prevent pockets of stagnant or recirculating air, especially in the vicinity of the generator air inlet.
When designing the air intake and exhaust of diesel generator room, we should pay attention to the matters which mentions in this article.
When discharging air vertically, because the generator is surrounded on all sides, can result in higher than ambient air temperatures being pushed into inlet vents.
These enclosures effectively form an enclosed space around the generator set and can be fitted with sound absorbing foam and air intake and/or exhaust scoops for redirecting noise and
The secret often lies in the generator inlet and outlet air shaft distance - a detail that even seasoned engineers sometimes treat like an afterthought. Let''s cut through the steam (literally) and explore
(1) openings in walls of a smoke extract shaft, or a return air shaft which also serves as a smoke extract shaft, or (2) openings in walls of a protected shaft when the openings have a kitchen exhaust duct
This information is provided to aid in the safe and proper installation of Generator Systems.
Each EDG set has a separate, independent diesel engine combustion air and exhaust gas system, as shown in Figure 9.5.8-1—Emergency Diesel Generator Air Intake and Exhaust System.
The primary regulator & hose can be run out a hole in the intake side for hot weather use, or on the exhaust side for cold weather use where the exhaust air keeps the tank at a moderately
Generator sets must be properly installed to ensure that cooling air is not restricted or artificially heated by nearby heat sources or from recirculation. Fortunately, installation influences can be simulated
