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 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

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

Or the same amount the engine is taking in? If they're connected and the compartment is sealed.
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

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.

:-)

Re: Diesel engine compartment ventilation

MarkSF, I have the same thing, one facing forward ducked along the top for about a foot supplying fresh air into the eng compartment, the other faces to the rear and it's hose goes to the bottom, and pulles air out of the compartment.

Re: Diesel engine compartment ventilation

"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.
