Title: What plastic material is the tank made of?
Post by: Waldo on May 07, 2008, 11:29:43 am
Hi,

I need to know which plastic material the fuel tank is made from?
Believe it's HDPE or PVC...

I recall it being mentioned in the workshop manual, but I don't have it at the garage where I am at the moment!

Anyone remembers or got the workshop manual at hand?

Thanks,
Valdemar

I think its HDPE.  you can try to burn the plastic (I know its not a great idea to set the tank on fire  ::) )  but polyeten should burn with a clear yellow light

are you thinking of running your murena on ethanol?

Might be the only option we have in a few years time  :(.... assuming we wont be fitting electric motors instead :)

Hmm... not ethanol I will be using diesel, and I need to do a little welding to modify the tank.
Don't go tell the car inspection though ;)

That's very unlikely considuering the current food crisis which is - at least to some extent - caused by the growing demand for biofuels!

ANDERS!!... if he wants to make a diesel Murena he is in his good right to do so... stop making faces of him!!  :P ;D :D

IMHO biofuels are an emergancy "stop gap" solution at best... as soon as people see the light we are headed for electric cars.. mark my words..!

Oups, I think I might have used the smiley incorrectly..... sorry! I jsut meant I was going to keep my mouth shut.
I'm full of respect for anyone who takes on a big project and completes it! :D

These will effectively be wind powered vehicles! - at least here in Denmark ;) The idea is to make an intelligent charging network that effectively stores otherwise unused wind energy in the cars during nighttime. According to some reports I've read, there's already being produced enough wind electricity in this country to power our entire fleet of cars - if they were electric.

But the only electric sportts caar I have seen so far is the Tesla, which is built on the Elise platform. However, instead of having an 800 kg agile car, the Tesla is a 1200 kg dog! So batteries really must improve by a lot before we can have "electric fun", IMHO.

Meanwhile, Waldo will probably get a lot of fun once he goes on the road - and black smoke frfom the tyres! :D

Hi Krede and Anders,

I don't want to get into this bio - electric power discussion, just read the big thread regarding all your different views on this!

I'm simply installing the a HDI engine because I like diesel engine (have allways been driving diesel cars, even before the commonrail days).
They offer very good reliability, economy, power and last but not least TORQUE  ;D


I have a bet going with quite a few people by now... Maybe some of you would like to join?
I claim that I will have a Murena HDI doing the below listed on 1 tank of diesel:
>20km/l
0-100 km/h < 9 sec.
80-120 km/h in 5th < 10 sec. (faster than the 177hk petrol Peugeot 206)!

I'm offering a crate of beer if I haven't succeded within 18 months from now...

Any takers?

... I guess I'll have to visit Anders and have a chat with him about electric cars when I get home then.... but as I see it, Its the most sensible long term solution for day to day transportation... well just have to save the fuel for the weekends in our Murenas :)

< 9sek in a Murena with a standard 1.9 hdi seems fast to me.
and 20km/l is more then TWICE of what I get with EFI... but hats off... and a cold beer on me if you pull it off  ;D

Who said anything about standard...  ;)

I expect to have it chipped and an intercooler installed before those performance figures can be reached.
I admit I might even need to change the ECU program during the test, but I'm confident I will get there...

My parents Peugeot 406 Estate does 17-19 km/l without problems. It's 1450kg, the front area a lot bigger and I believe the CW value is very similar to the Murena (if not higher when the headlights are down).

If I'm struggeling to make it, I will run 175/55-15 front, 195/55-16 rear...

Hi
The German magasine Auto Motor und Sport has just tested BMW 120 diesel (2.0L turbo and 204 HP) against the Golf GTI petrol (2.0 l turbo and 200 HP).
And the magaisn found the BMW the most sporting drive!
