Pre-ignition Cylinder Pressure of an Engine

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

Pre-ignition Cylinder Pressure of an Engine FORMULA

\(\large{ p   \; = \;   p_o \; CR^{\gamma}  }\)         

Where:

\(\large{ p }\) = pre-ignition cylinder pressure

\(\large{ CR }\) = compression ratio

\(\large{ p_o }\) = cylinder pressure at bottom dead center

\(\large{ \gamma }\)   (Greek symbol gamma) = specific heat ratio
