Analysis of bronze hybrid composite for spark ignition engine piston

Abstract

The development in automotive industry leads to economy and comfort of the vehicles and thus forces the designers to develop new materials for the improved performance. In this work, Bronze hybrid composite with Aluminium and Silicon reinforcement for spark ignition engine piston was fabricated through vacuum stir casting process. Conventional machining techniques such as turning, drilling and boring etc., were used to manufacture the piston. Thermal analysis on the composite piston was carried out using Finite Element Software ANSYS. The mechanical properties tensile and impact strength and hardness of the composite were measured. Wear analysis on the composite material was carried out and wear rate was calculated. The results were compared with the existing material and found enhanced with bronze hybrid composites. Emission test was also carried out and found improved. Microstructure examination was carried out to study the structure of the composites.
