Hi, encountered a funny story today, thought to share it with you all:

went to the inspection today, to get my car licensed. Everything fine until examinator asks what kind of engine is there inside.

A: "So, thats a nice weight balance *pointing to the vin tag*, what kind of engine is in there".
B: "Well its a rotary engine"
A: "Ah, yes yes, its a twin rotor ? *looking on the 13B gravure on the UIM*"
B: "Yes it is."
A: "Nice, how is the sound ?"
B: "Very smooth and decent with a stock exhaust"
A: "Can you start it, I want to hear the sound. *Starting engine , purr purr purr* Thats ok, that was it, have a nice day."

Got the papers, later I noticed that they did put up the car as 2616 ccm *WAAH*
Per se I ve got nothing against it, but not if I have to pay taxes for 2,6 liters !!
Figured he heared TWINrotor and multiplied existing ccm per 2

That and my license plate clearly states: RE 1308 let me repeat this, in case it has been overlooked: RE 1308


Have a nice laugh

In motorsports, apparently the displacement of rotary's gets multiplied by 2, maybe that is the case with your area.

I already heard of this rule, but my first FC -> 86 NA was tagged correctly with 1308 ccm.
So I will take the 86 FC paperwork with me to get that error corrected ...

paying taxes for 2,6 liters while in reality having 1,3 liters must be the royal pain in the .. you know where lol

It's like this in the uk, but of your lucky/clever you can get it changed.

I seem to remember some bull crap about "Converting rotary displacement to compare with piston engine displacement." It always came out with the 13B having somewhere around 2 liters. I've seen it on the old top gear road test where they show the FC's stats against the Porsche 924, and also somewhere on an aftermarket parts site... It drives me absolutely insane. I can't stand the fact that people won't accept 1.3 liters as the engine's displacement.

That's like calling a 4.3 chevy a 5.7. Or a cat a dog. Or a apple an orange...

Wait, scratch that. The whole thing's just bull **** to begin with. Get it right people! It's a 1.3 liter Rotary! Good luck with getting the legal documents changed.

Displacement comparisons are foggy anyway since it's (kinda) a 6-stroke engine. 3 rotations of the ecc shaft for any given chamber to complete a full cycle. 1.3 is just the volume of 1 chamber times 2, for 2 rotors, but there are actually 6 chambers, 3 on each rotor, for a total of 3.9l. I don't know where the 2.6 number came from, it doesn't seem to based on any mechanical equations I can think of.

If you really want to confuse the parts store guy, tell him you have a 3.9l 6-chamber 6-stroke. :P

eh, six stroke is kind of a weak premise. the "combustion chamber" only undergoes the 4 cycles ("strokes" as per the reciprocating engine term) of the otto cycle. aka intake, compression, expansion, exhaust. I don't know much about how they calculate it as of right now, but if a manufacturer classifies a part as having some quantity of anything, unless someone has gone the lengths to calculate and prove with evidence a different answer, i don't see how someone can legally just call it a larger displacement. I understand racing wanting to level the field, but at the same time they could just call it 1.3L and "award" penalty weights or something like that.

Update Steven?

This is all quite funny. It's always legally been labeled a 1.3L. So, that's what it should be on paper. We're not talking "motorsports"... we're talking street. What is going on in Luxembourg?

I've always wondered if people who have to pay taxes in Europe based off their engine displacement LOVE the fact that they have a 1.3L rotary.

This reminds me of how man times ive heards the chevy 5.0 referred to a 350 and a 5.7 a 396

StevenL5975

Yes, there is an update Got the error corrected, its now 1308 ccm

To put a long story short, this is how it went:

Had to pass the inspections again, failed last time due to rust ...
On the inspection lane once the repairs had been checked and confirmed I ask them where I could change that error in the papers.
Inspector didn't know the answer and asked his boss, boss arrives and here I ask again.
Boss told me that this is impossible, rotarys are measured different ... Ok, we had a conversation for about 2 mins and he insisted it to be classed as an 2,6 liter engine.
As soon as I told him that I have the exact same car twice, of which the other one was classed correctly he didn't know what to say, If I insist it beeing changed I have to pass aggreation and discuss it with them. What do I do ? Well of course I pass over to the aggreation guys and head to the reception. 10 people before me, lucky day this might be done in only 3 hours
Once my turn, I ask the same question again, always polite and friendly. Turns out the department boss itself is sitting behind the desk so he starts browsing through documents...
The usual discussion on how rotarys should be measured for ccm starts again. (Did I state already that Im slowly beginning to hate this discussion? )Some browsing later finding a few renesis engines and 12As aswell as some 13Bs he scratches his head and instructs a colleague to check and inspect my engine again. There I wait for another one and half hour, and finally the magic happens and I am called to another guichet, getting my papers back with the error corrected, finally I am driving an 1,3 liter FC again.

That was it, 4 hours lost with argumenting, waiting, phoning and boring is finally over and I can go back to work.
Did I mention that my boss was not that happy at all over my prolonged lunch time ?

Am I alone with this administrative trouble to register an 13B with its correct 1,3 liter displacement ?

@TheAbsence
In Luxemburg the taxes are calculated on the displacement and year of the car, maybe some other factors I am not aware as well but in general thats how it is.
I love the fact that I have to pay only 25 € (bout 30 $) taxes a year if my car is more than 25 Years old Lucky me
On my old crappy '91 peugeot 309 I paid roughly 200 € per year.
