To calculate the PSI from Compression Ratio:
\[ PSI = \left( \frac{X}{Y} \right) \times P \]
Where:
Compression ratio refers to the ratio of the volume of an engine cylinder when the piston is at its lowest point (bottom dead center) to the volume when the piston is at its highest point (top dead center). It is a crucial parameter in internal combustion engines, as it directly affects the engine’s performance and efficiency.
A higher compression ratio means that the air-fuel mixture in the cylinder is compressed to a smaller volume before ignition. This leads to a more efficient combustion process, as higher pressure and temperature are achieved during ignition. As a result, more energy is extracted from the fuel, leading to increased power output and improved fuel efficiency.
Let's assume the following values:
Using the formula:
\[ PSI = \left( \frac{10}{1} \right) \times 14.696 = 146.96 \text{ PSI} \]
The PSI is 146.96 PSI.
Let's assume the following values:
Using the formula:
\[ PSI = \left( \frac{8}{1} \right) \times 14.696 = 117.57 \text{ PSI} \]
The PSI is 117.57 PSI.
