EGR removal - benefits
Hi guys, just wondering if removing the egr on the b200e will make the car run differently....better or worse. Any ideas?
Re: EGR removal - benefits
Am I being thick? but the B200E doesnt have an egr? K-jet injection.
On most modern engines blanking of the EGR is of now use as the EGR is fully closed at WOT or when the managment detects sudden increase in throttle

Aussie spec did, Kelvin, none of us lot did, might be worth a post on TBricks about it?

Re: EGR removal - benefits
todays interesting fact...
Re: EGR removal - benefits
My egr on my 87 (technically B200EA) was blocked off on mine i got it. i don't know if it was the fact it was blocked off or the fact that it had it but it was a bag of s### compared to my 86 B200E. block it off see how it goes. if you don't like it change it back.

Re: EGR removal - benefits
How is this done?
Re: EGR removal - benefits
On mine where the twin exhaust egr pipes come up to the radiator and merge into one, just after that merge bend there is a massive bolt with hose clamp o there. where it meets on the intake pipe is blocked off by something unidentifiable but a decent size bolt should work to plug the hole

Re: EGR removal - benefits
So basically....stop the egr going into the black plastic....easy
Re: EGR removal - benefits
Pretty much. from what I've seen there's a valve or something the attaches to the intake and goes to a pipewhich goes to the exhaust side. mines missing libt pipe and valve.

Re: EGR removal - benefits
now we're talking about Pulsair and EGR in the same topic!
the EGR is the Exhaust Gas Recirculation system, it has a pipe from the exhaust manifold behind the rear of the engine to the egr valve and behind wich sits below the intake manifold, behind the valve is a pipe that is connected to the intake manifold. the valve is operated by vacuum and depending on the vacuum it lets a portion of exhaust gas back into the intake manifold for a more complete combustion. the downside is if the valve becomes slightly clothed, then it stays open and lets the exhaust gasses through when you don't want it, most of the time ruining the engine's idle and pickup
the best thing to do is to completely remove it. i've done the same on my 360 last year but i see i didn't put it all in pictures
http://www.volvo300mania.com/forum-uk/v ... 61#p165161
the pipe can be completely removed and blocked with a hydraulic plug, the port in the manifold is M14x1.5 thread, so a small bolt can do too
the valve is held on the engine with the same bolts as the flamebox under the intake manifold. there is a pipe from the valve that goes to the intake manifold; on top of it. remove the pipe and block the hole off, i've used a stainless plate; you can just see it here on the middle of the inlet manifold
operating the valve is a thin vacuum line, it goes from the inlet manifold to under the manifold where a small valve is bolted to the engine/cil head; you can pull it off this valve and leave it. as long as you block off the port in the intake manifold or you'll have a vacuum leak
then there's Pulsair, this allows fresh air to mix with the exhaust gasses just behind the exhaust valves. the natural vacuum that exists in these lines draws the fresh air in. the effect of this is that the air allows the exhaust gasses completely combust; reducing exhaust gasses.
under the exhaust manifold there is a port/pipe at each cilinder, the pipes merge and are split over 2 one-way valves. the one-way valves are connected via a single hose to the pipe between the AMM and airfilterbox.
normally this system won't have any effect on the engine's idle or performance but it will make the exhaust gasses cleaner.
simple way to remove this system is to block off the hose between the one-way valves and the pipe between the AMM and airfilterbox, but the pipes under the exhaust manifold tend to rust/corrode and eventually start leaking making noise etc.. mine were corroded and leaking so i've completely removed the pipes and made a few blanking plugs on the lathe.
