Skinned our hearts and skinned our knees. Goodbye my friend it's hard to die. When all the birds are singing in the sky. Now that spring is in the air. Pretty girls are everywhere. Think of me and I'll be there. We had joy, we had fun. we had seasons in the sun. But the hills that we climbed. Were just seasons out of time. Goodbye Papa please pray for me. I was the black sheep of the family. You tried to teach me right from wrong.
2. Effect of Gas Pressure Behind Piston Rings In reality the design of pistons and rings directs gas pressure arising from combustion on to the top and to behind the piston rings, pushing them against the cylinder with much higher pressure, improving their sealing, but causing greater friction losses.
How Piston Rings Affect Horsepower. The rings seal the pistons to prevent air and oil from being drawn past the rings into the combustion chamber during the intake stroke. During the compression stroke, the rings make sure the air/fuel stays in the combustion chamber and is fully compressed before it is ignited. During the power stroke, the rings prevent pressure from blowing past the pistons as the burning gases shove the piston down. And during the exhaust stroke, the rings make sure all of the spent gases are pushed out of the exhaust port.
