Ahhh Yes, Ahhh Yes....
Engine Capacity...
ok...just a quickie...
what does the 3.8ltr bit mean in terms of engines?
i used to think it was how muhc oil it help but some said it wasn't....
is is fuel related? Just want to know what engine capacity is....i guess....
aZK.
Wanted to buy:
1. T5 V8 Bellhousing and Clutch fork assembly suit VP
2. V8 Tail Shaft, T5, Suit IRS VP
3. T5 VB Gear Box
PM Me if you got what i need...

well actually its 3791cc but i am a pedantic bastard lol

Interest.
Even if you got an Scanning Electron Microscope and pointed at my interest in this subject you still wouldnt be able to see it......

It's how much unleaded petrol it takes to fill up the cylinders.
Ill try and go in a bit more detail for you, incase you cant be bothered fining out on google the term "engine capacity explained" would probably find a good set of results.
Anyway....
In the engine you have the cylinders right, say, a v6 (which is what you're probably talking about). Each of those 6 cylinders have a head inside them moving up and down (google engines if you didnt know that). The volume of the cylinder that the head travels through is 3.8 /6 = around 620mL. Meaning you can fit 620mL of stuff (petrol) into there. Things like stroke and bore will widen the cylinders and increase the distance the head travels to increase the engine capacity.
I think thats all right, if someone wants to get pedantic feel free to pick up mistakes
Ok you're nearly right. The head is something completely different. You mean the piston crown.
Anyway....
most internal combustion engines have x numbers of cylinders in various formats ( ie single, V, straight, boxer, radial etc). The rotary engine is different again it has at least one rotor and no pistons.
The Piston of a normal engine is connected to the crankshaft via a conrod. The piston moves up and down the cylinder. The bore area multiplied by the piston stroke is the swept volume of the cylinder. If your engine is a V6 then the total swept volume of all 6 cylinders is 3.8 litres (in the old money somewhere around 240 cu inch). If the bore diameter or the stroke of the cylinder increases then the swepth volume increases.
The head of an engine contains the valves and the equipment to operate the opening and closing of these valves (to let fuel/ air mixture in and exhaust gases out). Engines with valve heads are usually 4 stroke engines and nearly all cars on the road (bar fiat bambinos, some suzukis etc) are 4 stroke
and operate on the principle suck, squeeze, bang, blow.
Hope this helps

yeh the above explains it well, however i believe with the 3.8L commies its a fluke that it takes around the same amount of oil (usually between 3.6 and 4.0L)
