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.

How much air pressure in comparison stroke in diesel engine?
In a diesel engine, the air pressure during the compression stroke can reach around 30 to 50 psi (pounds per square inch), but it can be significantly higher in some high-performance engines, sometimes exceeding 100 psi. This high pressure is crucial for achieving the necessary temperature to ignite the diesel fuel, as diesel engines rely on compression ignition rather than spark plugs. The compression ratio in diesel engines typically ranges from 14:1 to 25:1, contributing to the high pressures observed.

What is the youngis modulus of rubber?
That depends on the hardness (durometer) of the rubber. It can be quite low and range from 100 psi to over 1000 psi. If it is very thin, then since it is nearly incompressible (poisson ratio approaches 0.5) then the modulus increases to a much higher value, depending on thickness , and can vary from 1000 psi to 10000 psi in general, and approach over 300,000 psi in the limit. You need to know the dimensions and durometer.
What is the compression ratio of 600 PSI?
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
What is 16to1 compression ratio converted to psi?
To convert a compression ratio of 16:1 to psi, you need to know the atmospheric pressure, which is approximately 14.7 psi at sea level. The effective cylinder pressure can be estimated by multiplying the atmospheric pressure by the compression ratio: 14.7 psi × 16 = 235.2 psi. Therefore, a 16:1 compression ratio corresponds to an approximate cylinder pressure of 235.2 psi at peak compression.

What is 11.31 compression ratio in psi?
You can't convert a RATIO (which is a pure number) to a MEASUREMENT such as psi. You get such a ratio by dividing two different pressures, for example.

If the psi of a amc 360 engine is 155. What is the compression ratio?
To determine the compression ratio from the psi (pounds per square inch) reading of an engine, you typically need additional information, such as the specifications of the engine, including the displacement and the type of gauge used for the psi measurement. However, a common method is to use the formula: Compression Ratio (CR) = (Absolute Pressure in Cylinder + Atmospheric Pressure) / Atmospheric Pressure. For example, if the atmospheric pressure is approximately 14.7 psi, the absolute pressure would be 155 psi + 14.7 psi = 169.7 psi, leading to a rough compression ratio of about 12.5:1.
What is the pressure of gas in cylinder during combustion?
Depends on the car. If it is naturally aspirated (no turbo or supercharger), then it's easy. Cylinder pressure = 14.5 (1 bar) * Compression Ratio. If however, it's forced induction: Cylinder pressure = ( 14.5 (1 bar) + Boost psi ) * Compression Ratio. For instance, in a naturally aspirated car with a 10.0:1 Compression Ratio : 145 psi = 14.5 * 10 Or in a turbo car with the unreasonably high 10.0 compression ratio with 10 psi boost : 245 psi= ( 14.5 + 10 ) * 10
How do you convert compression ratio and psi?
A 1:1 ratio is equal to 0 PSI. 14.7 PSI is equal to a 2:1 ratio. Just multiply your ratio by 14.7 to get PSI, or divide PSI by 14.7 to get ratio. This is only in a perfect cylinder where valves close exactly as the piston reaches the bottom and stays closed the whole way, and if no air bleeds out from the valves, or between the piston and cylinder wall. Not to mention the difference between if it's hot or cold. Plus, according to the math problem, if you had a compression ratio of 1:1, you would be pushing 14.7 psi. So there isn't any REAL way of telling an engines compression ratio without getting the specs for everything.
What should the compression be on a 1986 na Nissan 300zx?
The compression ratio for a 1986 Nissan 300ZX with the naturally aspirated (NA) engine is typically around 8.3:1. It's essential to maintain this ratio for optimal performance and efficiency. If you're checking compression in terms of pressure, healthy cylinder compression readings should generally be between 140-160 psi. Variations from these numbers can indicate engine wear or issues that may need to be addressed.
