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.
