Prolly a silly question, but how are the cylinders numbered?

Hopefully this diagram will work OK......firing order is 1-5-4-8-6-3-7-2 passenger side (1) (2) (3) (4) front --------------- rear (5) (6) (7) (8) driver side

It all started a long time ago when early humans needed a way to quantify, count, and measure things. It started as a simple tally mark according to evidence found on bones from about 35000 years ago. About 3500 years ago, something more significant was needed for the more complex societies, such as the Mesopotamia base 60 system and the slightly newer Egyptian base 10 system. Because of this concept, it became possible to put things in a sequence that has a logical meaning. Flash forward about 3000 years, the automobile companies use an internal combustion engine which can use only one cylinder or many. In the case of the multiple cylinder engines, it is useful to number them for assembly and trouble shooting purposes. For the Y Block V8 engine, they numbered the cylinders 1 - 2 - 3 - 4 from front to back on the passenger side and 5 - 6 - 7 - 8 on the driver side. And that is how cylinders are numbered.

That's what I like a straight answer for a new guy ... Listen to what Greenbird said.

Tough crowd for Friday humor! What I wonder is why the real number 1 cylinder is on the other side?
|
|
By GREENBIRD56 - 15 Years Ago

'Cause it's too hard to reach the spark plug wires when they're on the bottom???? Louis Chevrolet couldn't tell left from right???? Ford engineers had already built a few million v8's when the others started - Maybe they knew something the others couldn't figure out??????

Actually you can number them anyway you want as long as you remember how you did it and adapt the wiring accordingly. I like starting from the back then working on the wires and plugs gets easier as you work your way up in the numbers! Hint: If you look at the heads you will see the passenger side head is forward of the drivers side by an inch or so. Normally number 1 is the furthest forward cylinder. Can you imagine how long it took a room full of Engineers to come to agreement on that the first time? Chuck in NH

I would say Ford numbered the cylinders the way they did so people would have to pay attention to what they are doing. The "scrub bumpkins" need it easy since they are on the lower end of the food chain. Y-Blocks and Flatheads are not for the simple minded.

A little scary that the "Ausie" way is the actual correct way since I believe on a Y, the drivers side cylinder is the closest to the front, by about the width of a con rod. It is interesting what a room full of engineers can come up with as a consensus.

Actually - in the world of construction equipment design where I earned my "stripes" as a mechanical engineeer - the system is more "Autocratic" than "Democratic". Basically, its virtually military- there is a fellow placeed in charge ...... and he decides, no voting allowed. I have worked in organizations where (many years later) - you could identify the responsible project engineer who directed the work by the final appearance and function of the product. Whenever you see a piece of machinery that was designed by committee - had no one's clear stamp of direction - its usually a total kluge!!! In the ancient world of hand drafting (in the USA) - the layout of the engine block would have had a prominent overhead view with the front of the block at left. (Always a top and left side view - front and rear views at the option of the creator) And the cylinders would be numbered left to right across the top view of the page - and the second row of cylinders the the same.......makes perfect sense to me. I still have .... and this is thirty years after the fact......a callouse on my right hand where the mechanical pencil fit in my fingers. It took a lot of years before I ceased to be in the bottom part of the "food chain" and someone else did the drawing for me.

You think that the engineers are very logical about how engine cylinders are numbered and then you find out the famous 1948 Jaguar XK straight six DOHC engine is numbered 6 5 4 3 2 1 FRONT TO BACK. Go figure. Pete

I didn't know if you were talking about a 6 cylinder or an 8 cylinder but the 6's are numbered from 1 to 6 and the eights I believe are numbered from 1 thru 8. On the other hand, do you know why in hebrew they read from bottom right to left? If you are right handed, try chizling in stone from top left to right and you will find it is a lot easier from bottom right to left and up the page.

Several, Several times but not from writing in stone, more from chizzling off rusted out nuts etc.

Now that we have got you agreeing that our engines are numbered correctly all we need is to get the steering wheel on the RIGHT side as well.

And then pretty soon you'll want our toilet flush vortex to rotate clockwise and put more than one trailer on an over the road tractor....wait, we already do that.

But the real puzzle is why numbers? What have they got against letters or even chisel marks? chuck in NH

They should have used hieroglyphs, or perhaps Linear A or B, or maybe even cuneiform. Linear A will be good because I believe it has not been deciphered.... so only Ford guys will understand it, anyway.
