The lowest compression ratio of a compression-ignition engine that allows a specific fuel to be ignited by compression ignition.
To convert pressure in psi to a compression ratio, you typically need to know the ambient atmospheric pressure, which is approximately 14.7 psi at sea level. The compression ratio can be calculated using the formula: Compression Ratio = (Absolute Pressure inside the cylinder + Atmospheric Pressure) / Atmospheric Pressure. Therefore, 160 psi would yield a compression ratio of approximately 12.9:1 when accounting for atmospheric pressure.

The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
Poisson's ratio is the negative ratio of how compression affects distortion. When an object is compressed in one direction it expands in two directions perpendicular to the direction of compression. The ratio is equal to d(transverse strain)/d(axial strain).
Dynamic compression ratio is important to engine durability by ensuring its compatibility with a specific cam and octane. A higher ratio means the engine derives optimal mechanical energy from an air-fuel mixture.
23:1 compression ratio
The compression ratio in an Otto cycle is the ratio of the maximum volume of the combustion chamber (when the piston is at the bottom of its stroke) to the minimum volume (when the piston is at the top of its stroke). It is a critical parameter that influences the thermal efficiency and performance of the engine; higher compression ratios typically lead to better efficiency and power output, but can also increase the risk of engine knock. In general, the compression ratio is represented as (CR = \frac{V_{max}}{V_{min}}).
The compression ratio in a jet engine is the ratio of the pressure of the air exiting the engine's compressor to the pressure of the air entering the compressor. It is a critical factor in determining engine efficiency and performance, as a higher compression ratio typically leads to improved thrust and fuel efficiency. It is calculated by dividing the absolute exit pressure by the absolute inlet pressure. For modern turbojet and turbofan engines, compression ratios typically range from 10:1 to 40:1.
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.
compression ratio=uncompressed image size/compressed size
The compression ratio for the 1995 Mustang is: 9.0:1
The compression ratio for NASCAR engines is limited to 12.0:1.
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
8.4:1 is the compression ratio for 04-07 STi's.
The compression ratio is simply the ratio of the absolute stage discharge pressure to the absolute stage suction pressure.
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Nothing. Compression ratio is usually displayed as 9:1, or 9 to 1.
