Good pdfs Paulo !

thanx to tonycb6 for that.

Some interesting maintenance videos by the tdiclub.com guys can be found here .

Plus a couple of direct link to the videos (to save them):

Fuel filter change
and
Snow screen cleaning [a must!!!!] + air filter change [soooo difficult]

Note that UK spec cars arent fitted with the snow screen so no need to look at that if youve got a uk model.

PD Motorsport Clutch

I know this particular thread starts off about a Revo offer from JBS but if you go down to post #9 Sarah's given info and prices for the clutches they supply there (Same as the ones already posted by Paulo ??)

Whats thte difference.... between ....

I just found this little nugget. You guys have explained this to me ... But I thought this may help more newbies....

Non-PD Vs PD

In a gasoline engine, a mixture of fuel and air is compressed and then ignited with an electrical spark. A diesel engine relies purely on compression to ignite the mixture. When air is compressed it heats up - ever notice how hot the pump and hose get when hand-pumping a bicycle tire or ball? The amount of compression required for ignition in a diesel engine is far greater than that used in a spark ignition engine. So upon ignition, a significantly greater force is applied to the crankshaft resulting in greater torque.

The previous 1.9 litre turbo diesel engine - in fact, in most modern diesels - used a system where the fuel air mixture was introduced via a common rail. These systems generate a swirling motion of the air around the intake valves through especially designed intake ports. This motion causes faster mixture with the fuel when it is introduced and thus more complete combustion. This, in turn leaves less unburned fuel and emissions.

Pumpe Duse is a new fuel management and delivery system that places a pump injector at each individual cylinder producing a finer spray for better and more efficient combustion. Instead of a pre-combustion chamber found in most diesels, fuel is injected directly into each individual combustion chamber under terrific pressure at precisely the right moment. The PD works like an overhead cam system, using cam lobes to determine the timing and amount of the spray into each cylinder. The new system reduces heat loss, results in a quieter, cleaner engine, faster cold weather starts and improved low-end torque.

Hope that helped SOMEONE ...

Only the fuel is introduced via the common rail ? Air comes via normal inlet valves.

Instead of a pre-combustion chamber found in most diesels, fuel is injected directly into each individual combustion chamber under terrific pressure at precisely the right moment.

Most car diesel engines abandoned the pre-combustion chamber ages ago, and have been direct-injection for quite some time, the quoted statement applies equally to common-rail engines and pre-PD TDIs, as well as PDs. The main difference is that the PD system achieves a much higher injection pressure than common rail.

The PD works like an overhead cam system, using cam lobes to determine the timing and amount of the spray into each cylinder.

If my understanding is correct, the cam lobes do drive the pumps to build up pressure, but there's also electronic control of each injector too. The wires to each injector run internally through the cylinder head, laying in the oil. See this rather techy post for more in depth details of the PD pumps/injectors.

Found this on my travels. A MAF made by Pierburg for the PD engine. Have already asked a friend in germany to find out how much it costs.

Pierburg PD MAF

No more Bosch.!!!

 

[Niall]

Well i have got my Pierburg MAF and it is going in tomorrow. According to some sites; due to the mapping of the MAF it can give between 5-10% power hike.

A very very [very] good site with TONS of technical pdfs about almost every VAG engine/car,,, and obviously even about our beloved tdi,,,
Parts schemes and most of all, tons of manuals!!
It's in russian but the few words in english make it usable and the main part of the pdfs is in english.

Hope you enjoy this very good stuff, have fun with it.

Since the old post by paulo lost its pics, I'll use my beloved attachments space for the tdifaq,,, and you say I never think about you guys!!

This is a 90hp engine. If anybody needs any info about this and the 110 engine pm me, I'll try and provide it. I'm quite well documented about it.

 

[Johnsey]

Excellent post Carlo, i guess that's the 110 engine?

 

[sssstew]

yep correct. the 130 is quite close, less the valves at the back for N75 and N18, and the fuel/injection system is totally different.
