Pierre Gillet Posted February 23, 2004 Share Posted February 23, 2004 I am envisaging ditching the charcoal canister of my 1997 1.6 K . It seems that one kg can be shaved there What is the down side ? Pierre Link to comment Share on other sites More sharing options...
Luke Beaumont Posted February 23, 2004 Share Posted February 23, 2004 Environmental unfriendliness? Pfffft Go for it. Make sure you appropriately blank off the fuel tank vent, and the line to the plenum chamber if there is one. Link to comment Share on other sites More sharing options...
Strangely Posted February 23, 2004 Share Posted February 23, 2004 Check this thread: http://blatchat.com/T.asp?id=39397 Particularly the link in the second post. I did this fuel-vent mod when I removed my charcoal canister recently. Seems to be working fine.

Myles Posted February 23, 2004 Share Posted February 23, 2004 Goodness gracious! When does the commission cheque get posted? Yes, it worked for me - and having just spent a weekend under the car pratting with the diff etc., I'd recommend jacking the rear of the car up and removing the RR wheel to make access to the side of the tank easier... ...I have *no* idea why I didn't do this myself - presumably I subconciously like jobs to be twice as fiddly as they need to be...

Nifty Posted February 23, 2004 Share Posted February 23, 2004 I have one of these and would be quite happy to ditch it...what exactly does the charcoal do?? Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted February 23, 2004 Share Posted February 23, 2004 Like it does in your Brita water filter. It filters!!!!!!! Actually, it filters the petrol vapour so that the car is greener blah, blah etc. I don't have one. I just use the vent mod kit and all is fine!!!

Dave_H Posted February 24, 2004 Share Posted February 24, 2004 Is there any MOT issues with removing the charcoal canister 🤔 Dave Link to comment Share on other sites More sharing options...
Strangely Posted February 24, 2004 Share Posted February 24, 2004 There are no MOT issues for my car, but it only has to pass visible emissions. I have no idea why the original owner spec'ed a cat. If my car did have to have a cat then I don't think i would have removed the charcoal cannister. Hmm, I guess that didn't really answer your question...

Luke Beaumont Posted February 24, 2004 Share Posted February 24, 2004 I'll find out in September for mine, but it went through SVA minus charcoal with nary a mention. Link to comment Share on other sites More sharing options...
JAG Posted February 24, 2004 Share Posted February 24, 2004 The charcoal filter removes the hydrocarbons from the petrol vapour leaving the tank via the vent. This reduces the hydrocarbon emissions whilst the vehicle is stationary without the engine running. This is one of the emmissions reducing bits of kit fitted to fully type approved cars but isn't needed for our type of cars. I'm surprised that Caterham bother fitting it. On normal tin tops the charcoal cannister can be fully sealed and the ECU will vent it's contents through the intake manifold periodically. Justin A closed mouth gathers no foot.

wfarrell Posted February 24, 2004 Share Posted February 24, 2004 i had the misfortune of basing an MSc on this fabulous subject... the canister is full of 'activated' charcoal - a 500ml canister normally has the ability to absorb circa 35g of HC vapour - typically, the canister is purged periodically via an ECU controlled solenoid valve located between the canister and the intake manifold. All carbon canisters have a vent to atmosphere - this is required to allow fresh air to pass through the canister during purging of the HC, and allow HC vapour to escape to atmosphere if the canister becomes saturated / solenoid stick shut etc. These devices are legal requirements under the banner of 'Evaporative Emissions' - these laws were first introduced into southern california in the mid-fifties to counteract the famous Los Angeles smog caused by hydrocarbons escaping from vehicle fuel systems. finally, whip it off your vehicle if your environmental consience can stand it ! ta, Will Link to comment Share on other sites More sharing options...

MorganMan Posted May 12, 2005 Share Posted May 12, 2005 My new kit did not include the cannister - not required in UK apparently. It passed SVA without. Link to comment Share on other sites More sharing options...
