Pre-ignition Cylinder Pressure of an Engine
Pre-ignition cylinder pressure, abbreviated as p, is the compression pressure of an engine.

| Symbol | English | Metric |
| \(\large{ p }\) = pre-ignition cylinder pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ CR }\) = compression ratio | \(\large{dimensionless}\) | |
| \(\large{ p_o }\) = cylinder pressure at bottom dead center | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ \gamma }\) (Greek symbol gamma) = specific heat ratio | \(\large{dimensionless}\) | |
