"there's no air in the exhaust"

Air is 80% Nitrogen and 20% oxygen. Exhaust is 80% Nitrogen and most of the rest is C02. It entirely depends on semantics, but you could say that exhaust is at least 80% air.

Hi, MarkSF
I didn't mean to correct you or be rude but you're wrong. Not literally if you wanted to differentiate exhaust gases from air but, then, there's no air in the exhaust.
What I meant it's because the whole idea of an diesel/internal combustion engine it's the expansion thru burning/explosion.
Again, don't get me wrong. Just a comment.

:-)

Anyway, the hoses help to direct the flow to desired areas - like the alternator.
The amount of air the engine is taking in, and the amount going out of the exhaust, are essentially the same.

Re: Diesel engine compartment ventilation

Probably about the same amount that the diesel engine is pumping out of the exhaust

Re: Diesel engine compartment ventilation

I wonder how much air actually moves on a static set-up with two clam shells. Mine both have screens too.

Re: Diesel engine compartment ventilation

I like the idea of running the blower when under power to both remove any diesel stink, and also to keep things cooler on a hot day. However, my blower is LOUD! I wonder if I can somehow soft-mount the thing to quell the vibrations.

Re: Diesel engine compartment ventilation

I have a universal diesel in a Catalina that has two vents. One is intake and the other is exhaust with a blower. I do not remember any instructions regarding the running of the blower. I check it occasionally to be sure it works and have not run it during normal operations. So far I have not smelled any diesel in the boat. I like the idea of using it to remove heat and may start running it when the motor is operating. If I remember one hose with the blower is up high and the intake hose is down low.
