Cylinder pressure vs crank angle
WebMar 30, 2012 · If you know what cylinder pressure is when the valves close, then you can plot the pressure during the compression stroke by simply assuming an adiabatic compression and calculating the necessary pressure points for each crank angle. WebExpert Answer. In-cylinder volume can be calculated as a function of crank angle (0) using the following equation:V = V_T + V_c + V_b + V_e * sin (0)Where V_T is the ….
