CC...Cubic capacity of what?

[BillyW124]

Right lads,

CC.... is it cubic capacity or cubic centimiters of

a. Air mass
b. fuel?

 

[camerafodder]

Its cubic centimetres. For reciprocating engines its the volume the cylinder that is swept by the piston (plus the clearance volume IIRC).

 

[Davo]

I I understand the question right, the answer is --- a and b!

Its bore x stroke x number of cylinders. Which fill up with air and fuel mixed together.

right cubic centimeters of...

Davo, so if i got a 6.3 beast what is it actually doing under there?

...for example of course!

It's the volume displaced by the pistons (in cubic centimetres) in one engine revolution.

 

[camerafodder]

right cubic centimeters of...

...volume, its just volume regardless of what its filled with. IE a 1 Litre contaniner is 1000cc of volume whether its filled with water, petrol or whatever.

 

[Apial]

.....swept space.

 

[BillyW124]

..volume of what though air or fuel?

i see....

.....swept space.

I have a picture of Mr Spock with a broom.....

right ok so what we are sayig is that what ever it is filled with be it air/fuel the more it can hold the more it can combust resulting in more power?

In simple terms that's pretty much it.

To coin the old phrase 'there ain't no replacement for displacement'

 

[BillyW124]

..i really thought it was the amount of fuel the engine can handle to combust at any one time

Thank goodness no. Imagine how long a 60L fuel tank would last in a 6.3L V8! 60/6.3=9.5 complete combustion cycles of the engine.

It's the volume of the cylinders, swept by the pistons, expressed in cubic terms.

corr blimey yes your so right....

 

[BillyW124]

Wow...strange thread. It's the volume of the cylinders, swept by the pistons, expressed in cubic terms.

 

[BillyW124]

why is it strange?

good question no?

Size is but one variable. Not all 2 litre engines have the same output. It depends on fuel, turbocharger, supercharger etc.
