Pre-ignition Cylinder Pressure of an Engine

on . Posted in Fluid Dynamics

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

 

Pre-ignition Cylinder Pressure of an Engine formula

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