Simple question regarding cylinders.
I'm a little confused over the concept of power that a cylinder has. When they talk about one cylinder being more effective than another (or let's say one of 200 HP and the other of 150HP) what parameters determine this? Is it the actual volume of the cylinder that is displaced during the combustion, the rate at which the cylinder moves up and down (speed), the relationship of compression of the fuel, the efficiency or what?
I'm talking about aviation piston engines.
Thanks.
