CC means

Dear sir,

It is volume.Cubic centilitres or litre.

sankar

1000cc to 1 litre

Sorry to be pedantic (oh no you're not..oh yes I am etc)

Cubic centilitres is a tortology... 1

CC is a centilitre! So presumably a cubic centilitre is a sort of 4th dimensional measurement!

it's Cubic Centimetres

Erratta..

Centilitre is presumably 1/100 of a litre not 1cc..but my point still holds good..

Centilitre is a measure of Volume.

"Cubic centilitres is a tortology".............?

When coining a new word or phrase, isn't it customary to give the origin / meaning?

OHHHhhhh, I got it! "Typo"

Yes I meant 'tautology' ...

Its not a new word at all... well not in my English dictionary it isn't... tort as in tortuous, twisting, coniving, devious...

Makes perfect sense to me,,, I wonder why tortoises are named from the word tort??

Maybe a tortoise is devious and coniving??

John.....

Poor old tortoises seem to be described as crooked. That's a bit unfair since they don't move fast, sleep lots, and never carry bags marked 'Swag'.

You've obviously never had a pet tortoise Kris...they move surprisingly quickly and it's damned easy to lose one in the undergrowth!

Yes, we have many a fine tortoises in America. Also, in Canada, where they are used for curling stones... Have you ever seen a game of curling? It's like four Mr. Rogers on the ice going insane with brooms. Only in Canada, do you think.

When I was raising lizards, I used to frequent a pet shop that was of the reptile persuasion. They also offered a boarding service for reptiles whose owners were going on vacation. One of their favorite boarders was an African tortoise that was about 2 feet in diameter, and had a rather spiky rim about its shell. This thing weighed a couple hundred pounds and could eat its weight in lettuce in about a day.

So if you want a tortoise, forget about that midnight raid on Galapagos. Get thee to Africa!!!

Curling is big in Scotland as well but they don't have the supply of tortoises. I think it is now illegal to import them into the UK.

Del,

CC is a centilitre! So presumably a cubic centilitre is a sort of 4th dimensional measurement

It makes for some interesting analysis as a phrase. I see what you're saying, but it can be really twisted about for fun;

A centilitre is a volume occupying the space of a 1cm cube. Nothing restricts it to having that specific shape, for example 0.5cm x 1cm x 2cm is still a centilitre. But by saying 'cubic centilitre' the meaning is specifying that the volume is enclosed in a cube and no other shape. So '2 cubic centilitres' must be the volume enclosed by a cube of side length ³√2 etc. An engine with a capacity of 1000 cubic centilitres would thus be a very curious shape. By the reasoning I've applied it must have some shaped that is only constrained by the fact that 1000 cubes must exactly fit. For example a 10x10x10 cube or 20x5x10 box, and all sorts of curious configurations.

Whilst a like your higher dimension engine, I think my own cube formed engine is more practical. We could of course deconstruct each others proposals, but I hear a Flat-Earther needs my assistance. No rest for the wicked as they say......

Yess..I see...and those square piston rings are a real bitch!

My plan is ruined ! All because of the painful phrase 'square piston ring' I shall have to go find a piece to fit.

ahem. Correction;

A centilitre is a volume occupying the space of a 1cm cube.

A slight allowance for my sentence may be required as 1 litre = 1 cubic decimetre etc.

This minor lapse does not however invalidate my oddly shaped engines principle. It is my wifes fault since she always confuses me about how big centimetres is. Shame prohibits me explaining.

Never mind Kris, maybe you should stick with the wankel concept for your oddly shaped volume?

John

LOL. I am not going to be drawn into expanding on this project. It lacks a rigid framework for expansion.

Too bad ... This was really starting to get amusing!

he he. I could get myself into so much trouble Bob. I'm just gonna let somebody else play with it.

It beats playing with it yourself......Iooooh can't believe I just said that!

But Wankels are based on cycloids. Kris, cycloids. Huh! Huh!

Everybody keeps telling me that. If Wankel was Brit I'd be tempted. I put Mazdas in crushers just for fun. Using cycloids was a perversion by thigh-slapping Germans. Now some petrol head is going to put me straight. Don't care, won't care. Wankels is weird.

A centilitre is a volume occupying the space of a 1cm cube.

Did you mean to write that a centilitre (1/100 litre, thus 10 cc) is a volume occupying the space of a cube about 2.154 cm on each side?

I whole-heartedly agree with the rest of your post, and believe that we could have much higher volumetric efficiency in internal combustion engines if we kept the things cubic. I believe a major reason for the low volumetric efficiency of the ICE is the fact that we simply lose bits of volume in the roundish parts of the engines. If we had no round places, we could count all the cc's going in and all the cc's coming out, and then easily find out where the losses are.

Conservatively, I think it unlikely that we would lose more than let's say 15 of the little cubes in a one litre engine: where the heck could they hide, after all? That's 85% efficiency, nearly 4 times better than current ICE efficiency.

Ken, you have my measure ! I tried to weasel my way out of that slight bad (#46 I think). You clearly have the flair to run with this and make money for me. A small percentage for initial concept is all I need. Having been able to find a link, I am still seeking backup to an earlier suggestion (elsewhere) for rifles with square profile bullets. The accuracy was beautiful in the TV program I saw. Proof is needed before I can attract investors, and as yet I am not inclined towards making a demonstration model. The benefits are huge. Not just accuracy, but space saving with the close packing munitions. Again, I would be happy to split profit if a suc..sorry, ' investor' can be found.

Doesn't the projectile fired by a 'rifle' have to spin? I guess we could have the helix angle in the fourth dimension to allow for squareness in the other three.

No, no no! Using a cubic bullet would do away with the need for rifling.

Have you never seen the film that shows the effects of rifling? In this door-buster (as opposed to block-buster, stay with me on this one), candles were filed from two "rifles" - one without and one with rifling.

The candle from the unrifled rifle (analogous to an unruffled ruffle, I believe), tumbled end over end and resulted in a (roughly) oblong hole in the target door (told you the terminology would become clear).

The candle from the rifled rifle spun about its longitudinal axis, retained its initial attitude of flight and produced a (roughly) circular hole in the door.

So, if we shoot a cubular (I may have coined a new word there!) bullet and it tumbles end over end, it will produce the same hole in the target as a cubular bullet spinning about its direction of travel axis. We'd need to determine whether the radically different motions in flight would have any effect on the flight time, length and direction. Given its less than aerodynamic nature, I'd go with the rolling motion being more effecient than the spinning - in terms of less energy lost to air resistance.

Another advantage of cubular bullents is that, even without exploding tip, they'll do more damage to a target than a smooth normal one (yeah, I know they deform on impact) by the corners tearing and probably not being hot enough to seal the wound.

The effect of the 'corners tearing' would be a trivial effect, the damage from a bullet comes from the hydraulic load that dewaters the tissues and the huge blood presuure excursions two ways, followed by the actual kinetic/mechanical damage to organs tissues and bones.

The ratio of the size of the exit to entrance wounds is explained by this hydraulic hammer/cavitation effect. Corners would be insignificant.

The crossbows mentioned earlier, caused loss of blood pressure via internal bleeding, plus the assorted infectious transmissions if the victim was slow to die. Thats why we use broad heads on opur crossbow bolts for deer- greater wound channel, greater loss of blood, quicker succumb of deer, less tracking.

2 different mechanisms for death.

I read the original ragsdale report when it first came out, no quick time videos then.

milo

What's this "quick time video" to which you refer? The one I saw was recorded with 35mm film transferred onto VHS (I don't think it was BetaMax).

But thank you for the compliment, I am older than I look!

You're such a girl!!!

Have you ever heard of a shotgun? Smooth bore, and doesn't really care about what gets shoved down the barrel. Close up, within 30 - 40 yards devastating. However, any further than that and you're screwed. That's when you want rifling to stabilize the projectile on all firearms. And it's why a sniper rifle using Browning 50 caliber ammo can take you out at well over a mile away... even before you hear the bang.

Well, Gosh ! Who'd have thought a square bullet could travel for so long. I really should keep tabs on old threads, but then again..........

LOL - guns laws are little different over here, so I've never had the chance to play with any. I suppose if I'd thought about it, I kinda knew that about shotguns, but only in a "conscious-incompetant" way. I was just following the line of thought on square bullets from rifles; shotguns just didn't enter my mind...in between the boring stuff that earns me money (it was very boring that day!).

I'll stick to bendy bits of wood, string and twigs with a few feathers...much quieter!

By the way, shotguns are especially good for hunting squirrels.

You were the freaks that invented it... Cubic centimeter!!!

You sure it wasn't some French person ?

Yeah, I think your right!

"But dear! It's 12.7 centimeters long!"

It is the volume of engine - cylinder area x stroke length x number of cylinders.

The value is usually rounded - a 1000 cc could be 985cc

Normally you want as many of these as you can get. Lets face it we're not going to save the earth so we might as well enjoy the time we have here. This is gonna sound really anti america but the reason i say normally is because the japanese are very good at squeezing out loads of BHP from relatively small engines whereas the americans sometimes have huge engines with quite low power outputs.

This raises a good question about what is the most power/weight efficient arrangement and what is a sensible engine size for payload/anticipated mileage.

My vote for say 4 adults 10,00miles a year.... 1,500cc should be plenty to give good performance vs economy. Inline 3 cylinder? V4? Deisel. dunno

(If I was feeling punitive I'd say 1000cc)

i jsut don't see why people want/need 3litre passenger cars (different if you are carrying a load)

I agree. If I had a family (which I don't) then I would want a car which could take the wife and kids to the shops. If you have a wife and kids then you probably don't have all that much money to throw away on petrol or diesel so you would opt for something like a 1600.

However if you have no wife and you want to get one then you would probably buy the fastest biggest engined car you could find to compensate for all the other social handicaps you have.

There is one third option and this is what i fall into. I ride motorbikes and these are not that good for pulling. Most women want to go out for a meal and not look like a power ranger when they get there so your choice of engine size is purely dependant on what performance you are looking for. Most of us have a death wish so opt for larger engines and as much power as you can get.

Also don't forget that the two stroke is a damn sight more efficient than a 4 stroke....

No valves, cams etc... plus you get power on every stroke!!

John.

Ah fond memories of messing with 2stoke engines...skimming the head opening out the transfer ports, chopping bits off the bottom of the piston skirt, primary compression plates... opening and blending the inlet port...drilling out the main jet!

And that's just the lawn mower!...

Del, you just described what I did the moment I bought my first motorbike a Francis Barnett, powered (loose term) by a mighty Villiers 2 stroke 197 cc engine churning out a gut wrenching 6 horse power!!!

Boy those were the days, I feel the need, the need for speed....

John.

Lawnmower ! Dude . . . check out my chainsaw:

http://www.videovat.com/videos/1023/chainsaw-v8.aspx

Now thats My kinda chainsaw. MORE POWER Oh Oh Oh

I'm afraid I'm an inline 4 stroke japanese bike kinda guy. Some think this is boring but the sheer acceleration of these bikes is mindblowing. There is no way I'm gonna tinker with these babies in an oily shed.

Maca!.... when I had a Honda I quite often used to rip it apart, split the crankcase to tidy up some bits inside....

It used to end up all over the lawn at the back of my house, but the satisfaction of putting it all back together and starting it can't be over estimated...

I've even stripped an engine down to replace a broken gear in the gear box at the roadside, took about 5 hours and had a lot of people placing bets on how many parts I'd have left over, but the satisfaction of finishing up and starting then riding off is immense!!!

John.

I know it is possible to do it and well done for what you did, but I didn't have the guts to strip down a £5000 bike. None of my japanese bikes have ever had any major problems anyway, reliability of the japanese bikes is very very good.

I swear this is true...

There's a saying in the racer bike community in America: "Give an Englishman a piece of metal and he'll find something silly to do with it."

Vermin i love that quote..... where did you get it from or do you know where it came from??

John

Electroman:

The first time I saw that statement was in Road and Track magazine, about 1958. It was included in an article as an unattributed "old saying". For some reason it stuck in my mind.

DickL

You got that right!..This expression started in the early '60's when the "bug-eyed" Sprite was introduced. One of the best little sports car around.......

When I ponder, I sits and thinks, then sometimes I just sits.

That's 'Frog Eyed'

I don't know exactly who said it first, but it came from the time when the Japanese bikes had come to totally dominate the race circuit. It was just one of several sorted references regarding British bikes. There was another joke about if you came out in the morning and there wasn't a puddle of oil under your British bike, it was time to worry. Also, whenever we refereed to British car and bike electronics (lights, switches, etc.), we always refereed to the company as a question... "Lucas Lights?"

But then all the British bikes disappeared. They're just starting to show up again, mainly as restoration projects, and some are really pretty. I have my eye on a particular Norton that may get hot wired one of these days.

Mmmmmmmmmmm say the N word again...I just love it when you talk dirty.

As a kid I rescued 1/3 of an old AJS 500 single which I found in the woods!...but didn't have the time, facilities or cash to do it up... only got as far as rebuilding the crankshaft and bottom end , several years I gave it to a guy who was re-building one, so at least it was some use...(mind he never even gave me a beer!!!

Citroen and Cibie referred to Lucas as "The Prince of Darkness"

Ohhhh don't forget the Triumph factory up in Hinckley.

They have been churning out some superb motorbikes again mostly based on the speed triple, bored out version of the old Trident engines...

Boy do they move oh so sweetly.... I've several friends who ride nothing else, starting at 985 cc for the Sprint with 120 hp approx right up to the Trophy at 1200 cc

AND they look great as well..... *drool*

John.

It's great to see Triumph once again building machines to lust after. Although the faster ones are slick, I'd have to say I am really attracted to the Thruxton (as I was to the Vellocette Thruxton, years ago).

Sprint ST....hmmmmmmmm.

Google that phrase about Englishmen and you'll find some strange stuff !

Think I prefer the older classic bikes !

I think you will find it applies to Americans as well, or maybe just engineers in general.

That's insanely good ! Love the way that dude is licking his lips as he zips along. It adds that schoolboy sense of fun to it all.Why the heck does he look like a Brit and sound like a German though ? Was it some cruel prank by American bike-pimpers ?

how do you insert pics into the thread?

Reefdiver, I was drinking a glass of cider and reading that advert....

Now my monitor has a coating of cider on it!!!

But nice one anyway.... made me laugh!!

John.

LMAO too. Damn near spray painted the wall. Translating womanese is clearly a refined art.

Do you think they have a translator on babelfish?

....I dunno but most of my chat-up lines seem to result in a slapped face, so I clearly don't get translated too well by wimmin. A bloke I used to know had the most outrageous lines I ever heard, but every once in a thousand he'd strike lucky. Trouble was that by then he could barely walk never mind make use of the situation. My wife resorts to real nasty measures to get my attention now- hiding the remote, cork-screw,fuses and so on. I suspect my occasional random comments about liking the new hairstyle/outfit/shoes are not fooling her. Some correlation with actual change might help me , but observing such things is not my strong point. The problem is that she does understand me.

One of your chat-up lines must have worked sometime, or you wouldn't have got married.

Have you tried suggesting she meets up with <insert name of female or gay friend> to ask their opinion? If it gets her out the house, it gives you the time to search for the missing <remote, cork-screw,fuses and so on>.

My slapped mush is a slight exaggeration, though your logic in deucing my success is without fault . Avoiding contrived chat-up works much better. I figured that years back when I noticed that gay friends got all the great girls. Good old conversation works much better. Why is it though, that women can talk to mates on the phone for hours when they are going to meet the same person for lunch later that day ?

Did you ever try saying to her "that deciding to marry her was one of the best decisions you ever made?"

Then make sure you have at least two other answers of equal import or she'll be chasing you with the bricks, á la E-man... "How about having kids?" she'll cook your favorite dinner, without your brick scrapings as part of the ingredients.

Her best decision was marrying me, and I'm the better cook*.

slap. slap..slap slap.... slap slap slap....... slap slap slap sla slap.

* Last night was a tasty supper. A courier turned up with some delicious oak smoked fish (trout). mmmm Just kind of snacked on it with some nice bread and ever so slightly salted butter. I also got some Salmon which awaits me this evening. The kids are gonna get baked beans again. Yes, I am a bas....

Dear Mr Devil...

Surely you grill everything?

Does Mrs Devil wear nice red high heels and red fishnets?
