Does anyone out there have info on the 1.2 liter TDI? I've got the peak horsepower, and peak torque specs, but am looking for torque/rpm curves, and grams/kWh vs RPM curves if possible. By displacement and design they seem to be just 3/4's of a 1.6 TDI, but all the specs I find are for the 1.9TDI. Do they even make a 1.6TDI? Not in the US I know (but the 1.2 isn't available here either, so maybe it exists somewhere???)
Thanks

BTW, here is what I have. It gets 78mpg stock in the lupo in economy mode.
The 1.2-liter TDI has an output of 61hp and a maximum torque of 140 Nm (103 lb-ft) is available between 1800 and 2400 rpm
-
The 1.2 is just a 1.9 with only 3 cylinders and a small turbo
The 1.6 is IDI and has never been build as a TDI (Direct injection)
More info is in the dieselsuperbike thread:

Shouldn't it be a 1.425 liter engine if we just cut a cylinder off the end of a 1.9?

Nope, they always round to the nearest tenth of a liter.

Okay, but that still gives a 1.4 liter instead of a 1.2 liter....

It sounds more like 3/4 of a 1.6.

The 1.2 TDI is a neat motor, I have driving one around the block here in Ottawa, Audi A2 Transport Canada test vehicle. There was an article in the newspaper about it a couple years ago, they were averaging 90mpg (4.54L gallon) combined city and highway, the car was tiptronic/CVT style (no clutch). Cool car, lots of space. Not alot of power but enough.

That's 75mpg in US gallons. Pretty darn good. From the power/torque curves posted, it looks like it's got as much power as a 1.6NA, and since it's a bit lighter engine, that should help a bit.

its alum.block and head right????i have a few pals interested in using this engine in an experimental plane single seat about 200mph,,,iheard the engine weighs around 150 pounds or so,,,would be an awesome aircraft engine!!!!awesome cause max revs on a plane engine is 3k or so,,,,imagine,,200mph,suckin down like less than 2 gallons perhour,wow!!

If the 1.2 has a VNT turbo...

:lol:
Kidding.. some known VNTs are nice & robust though (unlike the 1.9 ALH's VNT-15).

I'm thinking I want one for my other passion... Sleding.
Do up a 1.2 the same as they have on the superbike, or mabey even more. If I could get it to 120-150hp it would be an absolute monster drop it into my Summit HMX 162" and drop the gearing way down, with that kinda torque I could have like instant track speed at any throttle point, with out a fancy roller clutch, that and on the big climb's instead of reaching for the GO juice I would just let it torque its way up... HMMM.
Anyone know what a complete 1.2 with ECU ect.. would go for???
Edit: and approx weight?
-
a bit off topic but I have mechanical drawings of both the 1.9L 4 cyl and 2.5L 5 cyl TDI engines. I'd love to get my hands on a drawing of the 1.2L and 1.4L 3 cylinders.

I dug up the bore and stroke of the TDI 1.2, and sure enough, it is not three-quarters of a 1.9.
1.2 TDI Bore/Stroke in millimeters 76.3/87
1.9 TDI Bore/Stroke in millimeters 79.5/95.5

70 plus MPG... why why why cant we buy these types of vehicles in the US?
Unbeleivable.

I have a source - want me to ask, really? I know about diddly on the 1.2 but it sounds like a cool motor for other purposes ( like superlight 4x4's).
-
Actually the bore and stroke of the 1.2 TDI is 76.5 X 86.4, the same as the 1.6 IDI of yore.
http://www.audiworld.com/news/01/A2TDI/chart.htm
Surprised me too. I thought the bore was 78.3mm with the 86.4mm stroke, both of which exist in the 1.7 SDI. This would make the displacement 1248cc, which would still qualify as a 1.2-litre displacement engine.

Do you have drawings of the 1.6L ? I could use that for my diesel subaru project. Althought, a 1.2TDI or 1.4TDI would be even better -- 3 cylinders is shorter and would fit in the engine compartment better. I was looking at kubota 3cyl diesel engines as a possibility too.....

I have 1.7 - 4 cylinder Lupo SDI engine code AKU year 99. Could you guys perhaps discuss this engine a bit more. In particular how this engine could cope with a turbo. What changes need to be made to account for oil cooler and piston cooling system, Ecu management and oil supply to turbo.
Been researching this for over a year now and managed to pick up a few bargains along the way. All new, Vnt15 , passat intake manifold and suitable fmic all for under £300 quid.
Any help with this project would be most helpful. Cheers
Sorry to hijack. But i thought whilst your on the topic. :)

I'd love to get a hold of one of these engines. Wonder if it would bolt up to a lightweight 020? (I know the 020 is bigger than an 02A, 02J or 02S, but it's much lighter).
