Description:The detailed design and analysis using SolidWorks and CFD simulations provide a comprehensive
approach to designing an optimized muffler system for the Mahindra Bolero. The project aims to
achieve a solution that balances noise reduction, engine performance, and regulatory compliance.
Future refinements will include prototype testing, followed by real-world validation and adjustments
based on performance data from physical testing.
The accompanying drawings illustrate the muffler design, including the internal baffle and chamber
configurations, perforated tubes, expansion chambers, and resonators, as well as the exhaust pipe
connections. The cross-sectional views provide an in-depth look at how exhaust gases interact with the
muffler’s internal components, showing flow patterns, pressure distributions, and noise attenuation
mechanisms. These visual representations will aid in understanding the functional relationships
between the muffler components and the overall system's performance , Claims:We claim:
