: Enter your engine's stroke and bore. The software sets limits for barrel height adjustments based on these parameters.
is a specialized engineering software designed for engine builders and enthusiasts to calculate and simulate port timing and area for 2-stroke engines . By analyzing the relationship between port durations and engine RPM, this tool helps users optimize gas flow for maximum power and efficiency. Key Features of V4.2.2
: Features a CAD window where users can drag cursors to set port positions and widths, with real-time updates to mean area values. How to Use the Software Porting Calculator V4.2.2
: 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
Optimizing 2-Stroke Performance with Porting Calculator V4.2.2 : Enter your engine's stroke and bore
: 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
: 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. By analyzing the relationship between port durations and
The software provides a comprehensive suite of tools to manage the complex geometry of 2-stroke cylinders:
