Exhaust Gas Recirculation...

[Boyboy]

Hi all

 

just installed a Simota Carbon charger (i think it's more accurately an enclose cone filter) and i asked the mech abt this tube leading from the engine block to the air intake just before the throttle body

 

i believe tt is the EGR and the mech didn't seem to know the term, but he said tt the exhaust gas is fed into the air intake then and offered to put a "breather" device to vent the EGR gases into the engine compartment.

 

so now i have a micro "open pod" which i think is to filter the exhaust gases being vented into the engine which wud otherwise be fed back into the intake

 

my intake is oily after the EGR inlet, no doubt due to engine oil mist. read somewhere here tt such gases will eventually foul the throttle, and I fully believe so

 

my point is, is the air breather device good? or will it reduce power or spoil the engine in any way? it seems counter-intuitive to pump hot exhaust gases back into the engine. i'm not too concerned if my emissions increases by a bit because of this mod

 

hope i'm not too long-winded. dun have a camera (believe it or not) but i'll try to take some pix when i get hold of my gf's N70

another question, does this breather thing need to be maintained? how often?

its not EGR, thats just a breather hose back to the intake manifold to burn off oil vapors. search for PCV on the web. lots of info there.

thanx

 

i have not seen the egr pie then. i only saw the pcv pipe.

 

argh. now tt is a really NOOB qn. at least i learned sth. now i find the qn quite stoopid

 

EGR was posted by genie47 on mcf, for pcv can google "pcv valve"
