What is the air pressure inside the top of a normally aspirated engine cylinder with an 11.5 compression ratio when the piston therein is in the power stroke and at full compression.?

Assuming an atmospheric pressure of 14.7 psia and a specific heat ratio of the air at 1.3 then the required pressure is: P = Patmp X rck
= i4.7psia X 11.5 1.3
= 351.74psia

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 does turbo-charging improves an engine's efficiency?
It does it by forcing more air/fuel into the cylinder than would be possible normally aspirated. This increases the cylinder pressure when it is ignited, for a longer/ stronger push on the piston increasing the engine's torque.
What should the cylinder compression pressure be in a 1991 dodge Dakota?
100-125psi
What is the cylinder compression pressure on 05 dodge neon?
150 to 160 psi
What should the cylinder compression be on a 2003 Nissan sentra with a 1.8 engine?
Cylinders compression pressure Sentra 1.8 : 192 psi
What is Silverado 5.7 engine psi?
Need to know the year. Oil pressure ? Or cylinder compression ?
What happens in the upstroke of the piston in the crankcase in a four stoke engine?
On compression the air is compressed, and on exhaust it is forced out of the cylinder.On compression the air is compressed, and on exhaust it is forced out of the cylinder.
What is motoring curve in si engine combustion stages?
Motoring curve is Cylinder pressure Vs crank angle curve, which is observed when no firing occurs into the cylinder that means the pressure which build inside the cylinder is basically due to the compression of the fresh air charge going into the cylinder.
What should the pressure gauge read for your auto?
Need to know which pressure you refer to, fuel, radiator cap, tires, evap, ac, cylinder compression, transmission?
When does an engine need to be rebuilt?
The easiest answer is when it fails a compression test. Buy a compression tester (farily cheap), and test each cylinder. If one single cylinder is below 120 psi, or if one cylinder reads 15% less pressure than the cylinder with the highest pressure, your engine should be torn down and checked. The problem might only be in the heads, but it's still time for some serious work.
What is a compression tester used for and how is it constructed?
The most common use for a compression tester would be to check the compression in the cylinder of an engine. It will tell you whether there is a problem with your rings, blown head gasket, or perhaps a cracked cylinder head. Older compression testers use a diaphragm or spring for resistance to measure the pressure, but there may be newer ones that are constructed differently.
What should the cylinder compression pressure be in a 2003 Mitsubishi Lancer ES 4 cylinder 2.0L L4 engine?
Around 230psi. Minimum is 170psi. I have the same exact car.
