OHV - 3 and 4 valves?

[SamSheepDoq]

Hi. I'm sure that some of you on the dev team have heard of Ford's pushrod Power Stroke 6.7L, and it uses OHV with not 2, but 4 valves/cylinder. So, will you guys be doing this in game? I'd love to build a 32-valve OHV engine! After all, pushrod rules, right Killrob?

You will be able to build 32V OHV... as soon as V16 engines are out.

Any idea when on earth those will be out? ._.

P.S. I'm wating on BOXERS!

I believe the devs said that V16s would be DLC. I was about to say that you should read the whats in/out thread but V16s aren't actually listed anywhere in that post. Hopefully a dev will correct that at some point

The boxer engine is another name for the flat four engine so, as it says in the link above, the devs are aiming to get those completed before release. However, it will be a while until the boxers make it into the demo because the devs said that they are going to work on the car designer and career mode before they add more content to the engine designer. Also, I believe that when they do start work on the engine designer their first priority will be V6s, because the V6 is by far the most common engine in that list.

Oh, V16s are there as fancy pants special edition content.

V6s will probably indeed be the next engine we do, though no new engines for a while as we're focusing on car design etc.

V16 is from the "Turbocharged" edition.

No, flat engines aren't always boxers. Boxers have opposite pistons sharing one crank pin, while flats can be boxers, a flat can also be just a flat if a piston doesn't share the same crank pin as the opposite piston.

Cheers for the correction My engine knowledge is a little rusty and I knew that boxers were flat 4s, but I didn't realise that they were just one type of flat 4.

Also, its nice to hear that the V16 will be in the game at release. I genuinely thought it would be put in after release for some reason

A 180 degree flat engine has ONE(1) crank pin shared by TWO(2) connecting rods/cylinders, one on each side of the engine.
A boxer (opposing cylinder) engine ALWAYS have only one(1) connecting rod/cylinder per crank pin.

So a v-4 or a 180 degree four cyl engine only has two(2) crank pins, a boxer four cyl engine MUST have four(4) crank pins.


Can't be any clearer than that.

If we have a Flat 4 and a Boxer 4, the flat 4 has two crank pins, but the connecting rods don't connect to each other. In the Boxer engine, it also has two crank pins, but the connecting rods connect to each other as well as these crank pins. Wikipedia this if you're still confused.

...... You are absolutly wrong.

The boxer (opposing cylinder) engine has the pistons on each side of the engine moving out at the same time, <--O-->, then in at the same time, >--O--<.
On a flat engine(180 degree), they move to the same side >--O-->, <--O--<.

No, head on over to Subaru's YouTube channel and watch. Here's a direct link to the video that will help you understand this - Learn About Subaru Boxer Engine Technology (notice this is from Subaru, themselves)

But that video shows it the same way RobtheFiend describes it, and how I've always understood it, each opposing piston goes away then towards each other


A Ferrari "Flat 12" is really better described as a 180deg V12, both conrods on a pair of opposing cylinders share a crank pin and they move as a pair in the same direction at the same time.

[RobtheFiend]

Even better point;
The Ferrari crank Daffyflyer described has 6 crank pins, 12 cylinders = 2cyl/pin.
A Porsche 911 has a crank with 6 crank pins, 6 cylinders = 1 cyl/pin.

Need any more info?

I guess I'm not explaining it clearly, and chances are we're all on the same page from how it sounds, so let's all just agree I guess.

Why not OHV 32 valve?
