Knowledge based inlet port design: A simple graphical method to design inlet port and flow simulation

Minimum intake and exhaust flow resistance you need to get to build a high-performnace engine. If all these facets are optimized and we add high RPM the result is high output. Everything we do is directly influenced by the valve seats and valve form in close proximity to the seat. Seat priority is the most important up to about 0.18 inch of the valve's diameter. Above that the port shape start to become the dominant factor toward good flow. This paper explains the basic ways to design the port shapes and testing the same by using ANSYS software.
