Simulation of Four Stroke Internal Combustion Engine [ ]

The aim of this paper is to study Premixed combustion computationally via variations in pressure, temperature, velocity and its associated varying swirl ratio in single cylinder during four strokes i.e., (Intake, Compression, Power and Exhaust). The model (single cylinder with one intake and exhaust valve) was generated using ANSYS Design Modeller, was meshed and simulated for Spark Ignition premixed combustion in FLUENT using k-e turbulence model. The geometry has the specifications of Bore, Stroke, Connecting rod length, Cylinder capacity, Clearance volume and Speed of 68.5mm, 72.4mm, 165mm, 266.67cc, 29.63cc and 1500rpm respectively.
