I am in search of ventilation requirements / chart /references pertaining to idling diesel trucks in an enclosed facility.
Point me in the right direction.
Any advise will be greatly appreciated


I don't know the answer however If you went to your local fire dept the might be able to point you in the right direction they have the same problem for thier firetrucks. The answer is  exceptionally complicated as you need to know the output of gases of the diesel engines that are going to used in the facility. To figure that you need to know the CUIN size of the motors and thier idleing speeds / 2.5. (A normal 4cycle combustion engine takes 2.5 rpm to cycle all cyclinders in to out. The .5 allows for the cam and crank rotation offsets.
Once you know that you know how fast the motor is putting "bad air" in the building or space. Once you have that you can figure with the current cuft of air how long it would take to fill the space with exhaust and or how many cuft per min you need to cycle in and out of the buidling. Its bests just to set up an air evac system to slide over the exhuast pipes though.
