What are the extra components on the top of this engine...?

[kev131]

I'm wondering what's going on with this engine?

I thought it was the power steering componentry... but it looks different from other versions I've seen - It's a 1984 2000 TC series 3 by the way.

Beats me unless it's some kind of preheater for cold climates?

[sdebez]

i would say its part of the emision kit, egr valve carbon filters, my series one had all that stuff that i imported from the states.

[sdebez]

i have picture some where of the layout try and dig out.

[mirafioriman]

Good spot. Useless junk then

[kev131]

So maybe a few more horses would be released if it was removed...?

What are the twin metal tubes over the motorhead? I can't understand where do they fit over the engine.

There are small holes in the exhaust ports that come up to a channel running along the top of the head. The pipes screw into that channel and the large canisters are reed valves. It was all part of an exhaust gas recycling system to reduce emissions.

Do you think it is removable Mick?

[Tas131]

Yes you can pull it all off, but you'll need some blanking plugs to screw in to the head. I'll post a photo of mine if I can track down the camera.

Mick is right,
 we had the emission control here in sweden in -83 but they changed to the kind you shown in the pics in the later models, we also had an EGR valve ,i can see that it sat on the right side of the intake manifold on that little knob!

But i cant se any in your pics, here the EGRs where full of exhaust stuff and broke down and later was a perfect place to suck in air in the wrong place, made the engine to run a bit strange!

Just as Mick say put blanking plugs in  the holes in the head and change the exhaust manifolde for an older one, Rip the rest off!

Thanks a lot Alf - Do you think that the system reduced the engine power?

I wonder is any data on resultant emmssion reductions (or revised Co2 outputs)available from Swedish spec cars...?

[Thotos]

The 'extra' stuff certainly seem like emission reducing equipment. While it is relatively easy to remove them and to plug the holes, you will not necessarily regain the lost engine power. Some low emission engines had reduced compression ratios and differently 'mapped' ignition (i.e. different distributors - some with vacuum advance) to cope with the reduced octane fuel which could be as low as 88 octane in some countries. Do you know which country the car is from originally?

[kev131]

No I don't Theo although it doesn't have US spec bumpers or speedo - Speedo is in kms and it's a LHD. Interesting extra comments though....

[mirafiori76]

Kevin,

Where did you get it from? I mean, what country?
