Comparison of Cylinder Pressure Data of a Gasoline Engine For Ideal Otto and Real Cycles

In this study, cylinder pressure changings of a 4 stroke gasoline engine were formulated as a function of crankshaft angle. Cylinder 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. The deviations of the cylinder pressure data determined by ideal system assumptions from the actual data were determined and illustrated.
