    I need to know how much actual force is acting on the piston.
    Hello: I know that the force in a combustion chamber of a gas engine is around 1100 psi. lets say the ratio is 9.0 to 1.

    How can I find out how much money I will receive on my income taxes this year I've made 22,000

    Do you meant 'pressure'?

    Well,



    If you have the area of the piston, you have the force on it :)

    To add to what Unknown said - the compression ratio is immaterial to your queston. The pressure when the air/fuel mixture is compressed 9:1 is much, much less than the pressure once the mixture is ignited. So if you aleady know that the pressure after ignitionis 1100 psi, just use the formula that Unknown gave you to determine the force on the piston.
