Cyan: mixture stays in the cylinder and compresses. White: spark; orange: burning gas; grey: exhaust. Colours are illustrative. Select a cylinder or pause at the next ignition. A teaching drive sets the shaft speed.
Equations used in the module
Equations Master rod: s = r cos θ + √(l² − r² sin² θ) Articulating rod: si = qi·ui + √(li² − (qi×ui)²) V = A(hhead − spiston − hcrown); pV^γ = constant on compression τgas = Σ (pi − patm) dVi/dθ Four strokes / 720°; firing order 1–3–5–7–2–4–6; prescribed RPM
