What's this thing in the engine bay?

finchy · March 22, 2015, 13:06

Am i right in thinking this is some kind of vacuum thingy? Something to do with the brakes? I can't see where the pipes connected to it go off to, i first thought it was the fuel filter but the pipes connected to it don't look like fuel lines. I was just wondering what it was and if it's a serviceable part that requires maintenance.

Cheers all.

It´s an evaporator catching tank for fumes created in the fuel tank. These can be under certain conditions "reused" by adding them into induction of the engine.

Charcoal canister.

Thanks, I never gave it any thought, at least I know what it is now.

The only attention I've ever given it is removing it to get to the aux belt.

+1 on needs moving to get at the aux. belt.
The charcoal filter is included on the Toyota service sheet:
Inspect charcoal canister every 2 years or 30,000 miles.

However, on each of the last four services on my 2 this has been marked as n/a or struck out!

It would seem to be low on the priority list.

Question from a Yank:
The cars sold in the USA do not have this device (what-ever it is).
If it's part of the evap system, why don't USA cars have it??
The charcoal canister on US Roadsters in under the floor of the rear bins.
Why is in in a different location on UK Roadsters?

I think charcoal canisters originated in america...? Either way it started off with some idiot in an office saying 'venting the fuel tank to the atmosphere is harmful to the eco system, so we must put some ridiculous device on to filter it'.
In short, I've binned every charcoal canister I've ever had on a vehicle. I don't like the mess or weight they add. One simple breather pipe for the fuel tank works fine for me.

How have you removed it on your '2? Have you bridged the breather pipe from the tank straight to the pipe on the air intake?

This was a description of one I found on google:
A charcoal canister is part of the evaporative emission control (EVAP) system in many modern automobiles, which is designed to keep gasoline from evaporating into the atmosphere. Rather than venting a gas tank to the atmosphere, an EVAP system can allow fumes to flow into a canister that contains activated carbon and is therefore capable of adsorbing the fuel vapor. This process, coupled with the closed fuel system, can help ensure that a minimal amount of fuel vapor is allowed to reach the atmosphere

Pulled everything out, from the charcoal canister right up to the intake manifold port. Then blanked the port on the mani. I just have a loose plug which was for the solonoid that opens up said pipe. The breather line coming from the tank I have just stuck a rubber hose facing downward on, so no water gets in and flammable fumes are kept away from the engine.

Thread revival.

So does this not affect emissions / running ?
