about formula one engines

[solitude_24]

umm.. about formula one engines how were they able to increase the rpm to about 19000rpm? just curious...

sincerely...solitude_24

By using a short stroke and big bore..................and many many others....................................

dear tsleng

what about the other devices that i have heard? how do they operate(e.g. pneumatically driven valves)

Well, I only know they have short stroke big bore. About others like pneumatic valves....................well I can't explain because I don't know how to.

 

[solitude_24]

thanks anyway...

umm does anyone else know how to increase rpm?

thanks...

All the parts are extremly lightweight. Ferrari's engine only weighed about 200 pounds I think.

 

[solitude_24]

thats a bit hard... but how were they able to get it at about 900bhp? thats incredibly puzzling...

can anyone help me with that...thanks

Yes! Its light. Very light.
Well, if you really want to know how a high revving engines is, just buy a Kawasaki ZXR250.

It has a 250cc, 4 cylinder, 4 valves per cylinder, DOHC(i think) and produces peak power at 18000rpm.

Buy 1 , and slice it open

 

[solitude_24]

how does a DOHC engine work?

Gotta love that site! Helps with sooo many assignments....

This is my kart engine and I've got it up to 16,190 rpm! Anything's possible really.

Its a 2-stroke right? How much power does it make?

 

[Dorifto]

Yes it is a 2-stroke and it makes about 33 HP.

Pneumatic valves are the same as normal valves, it's the springing mechanism that is different. In normal valves, the valve spring is exactly that, a spring. As in a coil of metal. A pneumatic valve uses a chamber of air at high pressure. When the valve is opened by the camshaft, the air is compressed. As the cam lobe falls away, the pressure pushes the valve back into the closed position.

For a 3-litre V10, the maximum RPM that can be achieved with conventional springs is in the region of 12,500.

To summarise the answer to "how can you get the max rpm to 19,000", you need to bear in mind the following points:

• The moving engine parts are mass-optimised, to reduce the inertia
• There is no flywheel (see above)
• The pistons and cylinder walls are manufactured to fit so closely that the engine cannot turn when cold
• All idential parts are the same weight to 1/1000th of a gramme, thus reducing vibration
• Lubricants are specifically designed for that particular engine

I'm sure that's not an exhaustive list, but it should get you started...

That sounds quite high, what class do you race?

125 cc?

 

[Dorifto]

Yes it's a 125cc. Here's he kart:

no alfano / mychron?
is that a ICC? or a TAG

 

[TsLeng]

Ooo yeah, thats a nice kart.

Yes there is a mychron and it's a TAG engine.

 

[Dorifto]

TAG:
And thanks TsLeng

 

[Lafora]

mind if i ask how you transport the kart to and from home?

 

[Dorifto]

In the back of our pickup truck. Hopefully soon this summer we will get a little trailer to hall around the kart and tools. That or just make a thing out of wood for the back of our truck for the kart to set on with the tools under it.

 

[Blake]

Damn that's nice! How much did it cost you all up (Chassis, Engine, Mychron, Tools etc.)?

 

[Dorifto]

Alot. I'll leave it at that.

 

[usernamed]

sweet... Went to Karting camp last summer and was the funnest I ever did...

 

[Dorifto]

What type of karts?

Oh and it would be nice if we moved this to here....https://www.gtplanet.net/forum/t7-12134.html

 

[Blake]

Alot. I'll leave it at that.

Well duh! I know it a fairly expensive sport, I've always wanted to get into it but the cost is what stops me. Oh well...
