Computer aided design and analysis of piston mechanism of four stroke S.I. engine

This paper illustrates design procedure, kinematics and dynamic analysis of piston of single cylinder of air-cooling S.I. engine at maximum power and maximum torque condition. It is the study of the geometry of motion. Kinematics analysis involves determination of position, displacement, rotation speed, velocity and acceleration and inertia force and dynamic analysis involves determination of tangential force, radial force, forces on bearing, and torque on the crankshaft. In this paper the complete kinematic and combined static and dynamic force analysis of a single cylinder, four stroke internal combustion engines are discussed. The Complex Algebra analytical approach is used for analysis is less time consuming if it is programmed for the computer solution. The pressure for one cycle at maximum power condition data for the analysis of the engine has been calculated by using Engine Pro V 3.9 engine cycle simulation program software. The computer program is prepared in visual basic language software for Kinematic and dynamic analysis of the engine at the every crank interval.
