JavaPipe Description

Calculate the size of a tuned pipe for a 2 stroke piston engine JavaPipe is a free and easy to use software that can calculate the size of a tuned pipe for a 2 stroke piston engine. The calculations are assuming a speed of sound in the exhaust gas, which is not known exactly; also, it depends on the temperature and thus on fuel/air mixture and external conditions. In JavaPipe, the gas conditions for methyl alcohol (methanol) and gasoline have been implemented. The results of the calculations can be used as a good starting point for experiments and fine tuning, deviations of +/-10% are surely possible.Usage:· Measure the timing of your engines exhaust and transfer ports in degrees (see below).· Measure the dimensions and calculate the area of the exhaust port opening in the sleeve.· Assume the velocity of rotation of your engine in rpm (dreaming doesn't help much though).· Either:· use the sliders to adjust the values according to your engine, or· enter the corresponding values into the text fields and press to update the graph.· Printing and Exporting only works, after you have adjusted the appropriate Java security settings of your Internet Explorer browser. If you use a different browser, you can run JavaPipe as a standalone application which has access to files and printers (see below).You could create a hardcopy of the program window, though, using your systems suitable tools.· You can manually plot the cones to build a paper model or to transfer the shape onto sheet metal by using the values of R and phi noted below each cone. Plot two concentric circles. Requirements: · Java 1.4 or later
