One number for your engine. THP measures whether your combustion process is still operating as itself — compared to its own moment of excellence. From GT-Power sweep to live test bench, in real time.
Every calculation is grounded in published combustion physics. The app generates diagnostics referencing specific chapters and equations from the standard textbooks.
Internal Combustion Engine Fundamentals. §6.2 discharge coefficients, §9 burn variability, §9.3 knock intensity thresholds, §11 HC emission sources, §12 thermal loading.
Introduction to Internal Combustion Engines. §2 thermal efficiency limits, §4.3 timing sensitivity — each degree from MBT costs ~0.1–0.3% ISFC.
An Introduction to Combustion. §4 flame speed and lambda sensitivity, §13 optimal heat release phasing at 8–12° ATDC for SI engines.
| THP RANGE | REGIME | MEANING |
|---|---|---|
| ≥ 0.90 | Resonant Combustion | Maximum coherence. Chamber, mixture, and flame fully synchronized. |
| 0.75 – 0.89 | Stable Operation | Efficient with minor asymmetries. No immediate risk. |
| 0.60 – 0.74 | Coherence Drift | Timing or mixture losing synchrony. Early degradation forming. |
| 0.45 – 0.59 | Pre-Knock Regime | Significant integrity loss. End-gas approaching auto-ignition. |
| < 0.45 | Critical Instability | Combustion coherence collapse. Intervene immediately. |
The same harmonic geometry that measures C60 fullerene, moons of Jupiter, and Pluto — applied to internal combustion.

STAR-CCM+ (monitor tables, field reports), GT-Power (GT-POST CSV), AVL FIRE (cycle output), any tool that exports CSV or JSON. The Smart Paste parser auto-detects the format.
The highest stable THP your specific engine configuration has demonstrated, learned per fuel profile. Coherence Loss tracks how far this engine has drifted from its own peak — not from a factory spec.
No. All computation runs entirely on-device. No data is transmitted to any external server. No analytics, no accounts, no cloud. The app works fully offline.
Asymmetric penalties match real physics: advancing timing past MBT is penalised harder than retarding. Per-variable decay rates (φ × k) instead of flat φ. HC emissions included. Peak temperature safety gate. Knock at k=3.0 — the most aggressive decay in the system.
Yes — dedicated profiles for E-Fuel Synthetic and Hydrogen Lean Burn with their own reference values and axis weights. Grace State learns the baseline for fuels that have no historical reference.
