Need to be explained about engines

Home  \  General Chat  \  Need to be explained about engines

I wanna know what's the basic stats of an engine.
I know about cylinder that's okay.
But I'd like to know what 1.8L or whatever the number of L means...
is it reliated to the cylinders?
And what it improves or makes worse?
Does it have an impact on the fuel you use?

The liters is the size of all the pistons added together, called displacement. It's the amount of air a piston can hold when the head is at the bottom, as compared to when it's at the top.
1.8L 4 cylinder. That's 450cc per cylinder.

...errr....nothing really improves it, or makes the displacement worse, unless you compare a pushrod engine to a DOHC 4 valve, in which case, the displacement is just wasted, not really made worse.

It doesn't have an impact on the fuel you use, but higher amounts of displacement requires more air and fuel in the combustion chamber, so you generally get worse gas mileage.

It's and amazing site, and will teach you everything you need to know. Once you've read all that and still have questions, being 'em here. :thumbs:

Ugh... :banghead:

Are you trying to confuse him?

the displacement is actually the distance from the highest point the piston reaches, to the lowest point inside the cylinders plus the bore of the cylinders times the amount of cylinders.
