Background/Objectives: The work is to optimize the weight to power ratio of an internal combustion engine. So as to achieve the desired result we have considered a composite cylinder.
Methods/Statistical analysis: A cylinder with composite material is assigned as Aluminum alloy LM13 & Magnesium alloy AZ91D by varying thickness of internal cylinder-115x120x200mm dimensions. Outer core material is assigned as cast iron with dimensions120x200mm with 5mm thickness. Considering HERO SPLENDER PLUS specifications i.e., single cylinder 4 stroke SI engine is considered as standard model for design calculations and dimensional aspects in this project the 3D model of cylinder with varying cross sections is done in CATIA. The 3D model is saved as .igs file and imported to Ansys, thermal analysis module.
Findings: The analysis is carried out. Assuming boundary conditions as 600° C at inner surface of internal cylinder, ambient conditions are considered at outer surface and convection coefficient h is 5 watt /mm2 Optimization is done by varying the thickness and material properties of internal cylinder material. Due to which reduce weight to power ratio resulting in producing high specific power and good mileage Aluminum alloy LM13 is best suitable.
Improvements/Applications: The best suitable application is in automotive industry, pressure vessels and hydraulic mechanisms.
