: Computes exact durations for exhaust, main transfer, and intake ports (including piston port and rotary valve inlets). Mean Area Analysis : Displays required mean port areas in cm2c m squared
: Use the graph cursors to set desired durations. For example, durations above 150 degrees typically set the exhaust port, while those below 150 target the main transfer. Porting Calculator V4.2.2
: Once timings are set, use the port CAD window to define the physical shape (roof curvature, max width percentage) and save the design as a PNG for actual machining. Technical Requirements : Computes exact durations for exhaust, main transfer,
The software provides a comprehensive suite of tools to manage the complex geometry of 2-stroke cylinders: : Once timings are set, use the port
: Enter your engine's stroke and bore. The software sets limits for barrel height adjustments based on these parameters.
