Kokimax

Kokimax is a steam engine indicator and valve tool that draws the engine's curves as engineering-accurate diagrams. The app has eight functions. Cylinder uses bore and stroke to calculate the working volume and shows the cylinder cross-section. Indicator presents a small measuring piston, spring, drum, pen and cord pulley. The Diagram page draws the pressure–volume loop, that is intake, expansion, exhaust and compression, and it changes immediately when you adjust steam pressure, cut-off or back pressure; you can export the diagram as a PDF, CSV or DXF file. Slide Valve shows the travel, face and lead of the D-slide valve, and Timing draws the valve timing as a Zeuner circle. Governor presents the balls and sleeve of the centrifugal governor, Power compares IHP and BHP power as well as efficiency, and Flywheel calculates the rim mass from the speed fluctuation. Drag the sliders and nine of your own engine diagrams and readings update immediately. Pro unlocks DXF export and all functions with a single one-off purchase of $5.99. The app works entirely on your device with no internet connection, account or permissions; it contains no real trading, gambling or betting.
