Puretech 1.2 (Four-Stroke Cyce)?

Unread post by Pasi80 »

Hello.

I am confused about my citroen engine cycle?

In the picture you can see the nearest piston (cylinder three) is up when the crankshaft lock pin is in place. In the picture it looks like cylinder 1 & 2 move same direction and same time, is this possible?

What I have heard, usual the 1 & 3 are in same "cycle" (nearest cylinder in the timing and nearest cylinder in the flywheel).

My car is
Citroen C3 1.2 SX III phase I (81 kwh, HNZ/EB2DT).

How the cylinder cycles goes in my car? Where to find information 😅?

I used to be indecisive, now I'm not so sure!

The article seemed to me to be a few facts padded out with AI drivel. I find it difficult to accept it was written by a human being and question the existence of the name and photograph at the end.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

If you go back to the link to the article Paul and scroll down to the footer you will find an 'about us' link. Have a look and then maybe reconsider your view about the authenticity. You could use their contact link and ask them of course!! :-D

I've seen what they say about themselves. Maybe it's a human being who's used AI but I still maintain it could've been condensed considerably to increase readability.

Agree!

Goes round in circles repeating 1-3-2 and waffling about timing, balance and "special crankshafts" before, in a dramatic twist, in the conclusion, suddenly mentioning a different during order!?!
You’ve understood the 1-2-3 or 1-3-2 firing order,
