PistonOne

PistonOne is an engineering-grade simulation workbench and educational platform dedicated to reciprocating internal combustion engines. Designed for automotive engineers, propulsion researchers, and engineering students, PistonOne bridges classical thermodynamic theory and modern computational analysis across 32 comprehensive engineering modules and 119 model branches. ### Key Capabilities: - **Foundations & Kinematics**: Cylinder volume geometry, piston motion kinematics, finite-rate compression/expansion, and air-standard cycle thermodynamics (Otto, Diesel, Dual/Sabathé, Atkinson, Miller). - **Combustion & Heat Transfer**: Single-zone and two-zone Wiebe mass fraction burned models, Woschni and Annand convective heat transfer correlations, crevice flow, and blowby dynamics. - **Gas Exchange & Turbocharging**: Isentropic poppet valve orifice flows, intake manifold filling/emptying dynamics, compressor-turbine turbocharger matching, and intercooling. - **Emissions & Reacting Flows**: Extended Zeldovich thermal NO kinetics, soot particle formation/oxidation mechanisms, chemical equilibrium, and exhaust gas recirculation (EGR). - **Interactive Visual Canvas**: Real-time indicator P-V and P-θ diagrams, heat release rate curves, and instant KPI readouts with zero-latency slider interactions. - **Offline Technical Documentation**: Built-in 225-page comprehensive theory manual and 140-page user guide with physical PDF pagination, worked examples, and multi-format reporting (CSV, JSON, Markdown, LaTeX, PDF).
