Mazda 1.3 turbo

[kriz_k]

i dont want to take anybody's side here
but the engine is what it says it is
if it was a 2.6 or so the ministry wouldnt allow mazda to stamp a 1.3L badge on it
i m not a mazda fan but these engines are great pieces of machinery
the only thing, is that its fuel economy is as good as on my 3.8 SC Grand Prix

Keep cool guy
This motor rocks and the owner has fun that's the point

Capacity is a function of a cycle, not a third or two thirds completed one. Every other positive displacement engine is rated on the whole engine (not part of it) doing working or firing on ALL cylinders.

The wankel rotary is the ONLY exception to this common sense rule if you listen to Mazda

If all of the engine "functions" then you need to tripple the displacements mazda print on their compliance plates, 13B = 3.924lt engine.

What people/enthusiasts/engineers/governing bodies etc get so confused about is that they try to rate the Wankel on a two stroke cycle or on a 4 stroke cycle and not on a Wankel cycle.

It can conform to any of the above so long as you have a basic understanding of time line events.

13B as follows

at 360deg (2 stroke)
=1308cc

at 720deg (4 stroke)
=2616cc

at 1080deg (Wankel)
=3924cc

The last one is the only correct one, none of the others are right because the engine has not completed anything, the way to confirm this is simple, leave out an apex seal ! See how the engine runs ........... it wont very well. the exact same logic can be applied to any other internal combustion engine when trying to find its operating principle and its associated displacement.

I took this from Ausrotary.com and as much as I don't like it, it makes sense.

Heres the link for anyone interested.
