How to test the cylinder pressure; Compression and leak tests determine health of an engineBYLINE: Ken CorkettKen Corkett
When the compression rises, the rings are probably trapped or worn. The oil works as a seal, helping to reduce the gap between the rings and the cylinder wall, which is causing the cylinder to lose pressure. If you can detect any crack, damage, or slit, be ready for a costly and len...
Subtract 14.7 psi, or atmospheric pressure, from the pressure of the air supply. If your air supply has a pressure of 100 psi, then 100 psi – 14.7 psi equals 85.3 psi. Step 5 Multiply the result of the last step by the piston area to find the pneumatic cylinder force. For example, ...
To calculate hydraulic press force, first find piston area from piston diameter. Then multiply the pressure in psi by cylinder area in inches. Divide force in pounds by 2,000 to get force in tons. Gather the Data Reference the necessary data, such as psi and cylinder piston diameter or are...
From that, it'd be possible to know the vapor quality right after the release so we can find the portion of liquid and volume inside the tank. The densities of both are known since it's saturated and pressure and temperature are known so it's possible to calculate the mass. During that...

crack a cylinder head or the engine block, then slowly damage your engine and car cooling system. In general, car coolant lowers its freezing point to around -35°F to -36°F to avoid damage caused by frozen water. So, have your car inspected and fixed soon to prevent more serious and...
1925: Pratt & Whitney (now one of the world's biggest aero-engine makers) builds its first engine, the nine-cylinder Wasp. 1928: German engineer Alexander Lippisch (1894–1976) puts rocket engines on an experimental glider to make the world's first rocket plane, the Lippisch Ente. 1926: ...
If enough coolant leaks into the cylinder (as when the engine is sitting overnight), it may even hydro-lock the engine and prevent it from cranking when you try to start it. Internal leaks such as these can be diagnosed by pressure testing the cooling system or using a block checker. ...
When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder. The only problem with nitrous oxide is that it is fairly bulky, and the engine needs a lot of it. Like any gas, it takes up a fair amount of space ...
