    IMEP is inversely propotional to displaced the volume of the piston(i.e air capacity)
    Are you sure? This action cannot be undone.

    but imep depends upon the indicated power ,and indicated power depends upon thermal efficieny for a given air fuel ratio,and combustion is more effeicient upto some air capacity .then how can you say it is inversely proportion to air capacity.
    i have read one formula for imep ,can u explain:imep1/imep2 =(density of air *volumetric efficieny*mass flow rate of fuel*indicated thermal efficiency)1/(density of air *volumetric efficieny*mass flow rate of fuel*indicated thermal efficiency)2


    explain the how it depend upon air capacity?
