Removing Charcoal filtering system?

[graham_172]

Has anyone removed this fuel vapour system from their car etc? It seems to be thereonly to push air/fuel vapur inot the air inlet system after the throttle body which I think hampers performance and makes the air/fuel ratio unstable at low rpm/idle.

Anyone got any views comments on this system etc?

 

[graham_172]

Hi all, i've removed the charcoal filtering system and blocked the inlet piping off neatly. There is less bogging just off idle. Wonderful EU regulations etc. My advice to anyone wanting to save a couple of kg's of dead weight then remove it all.

As useless as the inlet valve fitted to feed pipe in n/s arch.

yeah this is done on alot of olders cars too such ast the celica gt4 and so on...the way i see it, is its there for a reason so im leaving mine be as with it there are no problems thus far

 

[len_beach]

Will this increase emmisions?

Might be a worthy mod'.

Any info'/pic's on location, removal etc?

 

[graham_172]

I can do a 'how to' once I'm happy the emissions light will not come on etc.

 

[murcod]

It's part of the emissions and your fuel tank actually vents into that canister when the engine isn't running. When you start the car the fuel vapour is sucked into the inlet manifold and burnt. It prevents excess hydrocarbons being released into the environment.....

That a basic explanation of it.

 

[graham_172]

thanks murcod. I've removed the whole system etc and car is running better just off idle. the tank vents to the filler cap aswell. that's why there are 2 pipes running into the tank.

I've spoken to gdi, k-tec and renault and it is fine to remove.

That would be good Graham

 

[MrMark]

does anyone have a pic of what such a canister looks like?

 

[graham_172]

I've been running the car for 3 days now. Emissions light came on. So you have to have the purge valve connected(tiny component) otherwise it gives a fault code443. I just cable tied it out the way


this is the pile of junk you'll be removing from the car. I'll do a 'how to' over weekend with pics.

 

[RichMcc]

Are these present on the ph 172 also?

 

[len_beach]

Looks like junk to me. I'll look forward to the how2.

 

[D1CKY]

I'm waiting to see the how to guide as well
And gains and problems you get when removing it

 

[graham_172]

no real problems removing it.

how to without pics tonight.

 

[graham_172]

1) open bonnet and locate piping to inlet manifold from charcoal filter. Cut pipe and seal with a stop or cap.(make sure this is done well or the pressure from the inlet will suck the cap into the inlet manifold causing damage)

2)remove front o/s wheel arch liner and you will see the charcoal filter(black box with 2 pipes and 1 sensor connected.). Undo 3 x 13mm long bolts. Keep filter upright or you will spill some of the contents. Unplug filter, disconnect piping.That's the filter gone!

3)from top of the car, pull the wiring back up and remove the sensor from the top of charcoal filter by twisting/pulling. It is a tight fit but only held by a rubber o-ring. reconnect cable and mount somewhere hidden with cable ties or tape. make sure you do this well.(don't want it falling into the fan etc)WITHOUT SENSOR FAULT CODE 443 WILL OCCUR.

4) remove all the pipe including the 2 clips on the chasis. do not cut the pipe till you have made sure you are removing the correct pipe. there are 2 that run under the car fairly near the exhaust on the off side of the car.

Once you have uncliped the pipe from the car and have reached the pipe clip by the middle exhaust mount cut the pipe and seal using another stop/cap. i have used a bolt with large thread pattern which is very secure. allow enough pipe so you can clip it back in neatly as pictured.

5) after refitting the o/s wheel arch and making sure everything is secure. Start the car and all should be well. This modification still allows the fuel tank to breathe through filler cap vent.

 

[len_beach]

How is this likely to effect emmissions?

 

[graham_172]

If anyone gets stuck while doing this then please don't hesitate to call me on 07922802910

 

[graham_172]

The engine will run better and cleaner without this system. it's just a renault system to keep the EU happy.

 

[len_beach]

So HC's etc won't go up come MOT time?

 

[graham_172]

I run a decat and this has not triggered the emissions light. Your car will still pass MOT. this system is adding fuel vapour to the inlet system after the throttle body which is not very clever.

I will have my garage run an emissions test shortly to see any differences made.

this system is only there to put vapours into the engine to burn off.

interesting......my solinoid is getting tappy, could be an excuse to cup the 182

 

[graham_172]

they won't go up because they are leaving the tank via the other vent.

Needs all the help it can get.

The cheek Engine cover was in the shed after a day of owning, as was the tool kit minus towng eye and foam..... this could be next

Need to do the wheels realy there not light plus don't help the brakes cool at all.

Shame realy s they look good.

 

[Gaz_]

Aye, they look mint against the black, especially now its lowered. I'm PC'ing it this week, and will probably remove half the paint, will this help remove weight?

No idea the biggest problem is the design doens't let air cool the brakes.

 

[M40 CUO]

My car is tapping from the belts sumwere etc is this due to the charcole filter as its making a tapping noise.

 

[graham_172]

could be the charcoal filter but it sounds like one of your timing/aux pulleys is knackered.

 

[pinky]

could you explain this more as i think i have the same prob, thanks

[AliasOmega]

if you want them pictures sorting out, let me know..

 

[Peperami]

I want to put mine back in!

 

[mattjk]

why?

Mines been removed for a while cant notice a blind bit of difference before or after tbh

 

[AliasOmega]

where did the pictures go.?

 

[mattjk]

even though mines been removed - its ticking
gunna have to put a resistor on it or something and take the bloody solenoid off i guess but f**k knows how to acheive that LOL

 

[AliasOmega]

^^ what did you remove

 

[Turner]

Is this the reason behind the ticking under the drivers side wheel arch?

 

[pinky]

does anyone have a pic of what such a canister looks like?

Its just a silly black rectangle box about 12". x 4" x 3". and mine likes to tick even though I changed it. Might just dump it off.

 

[DrR]

pics! As i have no idea what thi thread is about
