Abstract
In internal combustion engine heat losses from combustion chamber through the cylinder wall strongly influences the thermodynamics of the engine cycle and an important part of the energy balance thatinfluences gas temperature and pressure, engine performance and emissions. The primary object of the present work to increase the heat transfer rate from existing cylinder block, for that three design is proposed in which one is actual design and other two is new proposed design. Mathematical and analytical studies were performed in order to optimize geometrical parameters for natural convective heat transfer from Actual cylinder block and proposed design of cylinder block for geometrical optimization. The transient thermal analysis in ANSYS v16.0 was performed on two different ambient temperatures; the first one is on 25oC & another one is on 45oC. Since the maximum temperature developed on all types of cylinder block design is same but the lower temperature is much below in proposed design-2 is attended. Hence the proposed design -2 of cylinder block has better performance and heat dissipation from the heating zone in the IC engine.
