The detection of knock by the band-pass filter has been set above 2.5 bar cylinder pressure and 960°C of exhaust gas temperature [17]. WebCylinder pressure – crank angle graphs were obtained for ideal Otto cycle by using obtained equations. In the followings section, the 4 stroke engine was modeled by using 1-D numerical analysis program and pressure data acquired. The graph obtained by theoretical calculations and the other one obtained by the 1-D model were compared.
