A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency.This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer . How did you do the compression test? If you cranked until you got the highest reading you did it wrong. For the test to be relevant you must pump the exact same numer of revolutions for each cylinder. A cylinder that gets 180 with 4 puffs and one that gets 170 with 10 is not within 10%. The throttle must be blocked open and all the plugs out. You can look it up in the vehicle's specs or do a compression test. Then, use the formula: Compression Pressure (PSI) = (Compression Ratio - 1) x 14.7 . This common compression ratios for diesel engines helps ignite the diesel fuel at high temperatures and pressures. . A 10 to 1 compression ratio is about 150-180 PSI. This depends on the . The actual amount of compression is relatively unimportant in a street car. You should be looking for all cylinders to be within 25-35lbs of each other. If one cylinder is 75lbs and the others are 150lbs, then you have a problem. I remember a compression test on a '64 Galaxie 427 side-oiler, compression was 100lbs all cylinders. It ran smooth .

The biggest factor is the intake valve closing point. The cylinder can't start building pressure until it's sealed up. A given engine will have distintly different compression test readings with different cams. Different engines with the same cam and different compression ratios, will read very similar in cranking compression. 93 octane gasoline can typically support a wide range of compression ratios, but it's commonly used in engines with compression ratios around 9:1 to 11:1. What gas to run with 12:1 compression? A 12:1 compression ratio often requires high-octane gasoline, such as 91 octane or higher, to prevent knocking and ensure proper engine performance.
Engine CompressionAtmospheric pressure at sea level is approximately 14.7 psi.A 9:1 compression ratio cylinder is compressing the air and fuel mixture to about 132 psi at sea level (9x14.7=132.3 .
Understanding compression test results is crucial for assessing the health of an engine. High compression ratios may indicate efficient combustion and a properly-functioning engine. This can be beneficial for performance and fuel efficiency. On the other hand, low compression ratios could be a sign of engine problems, such as worn-out piston .

Use the standard compression ratio fuel octane chart to know the fuel suitable for your engine. Use low-octane rating gas for engines with a low-compression ratio. For engines with a high-compression ratio, use a premium or super-rated fuel. You Can Also Read: How to Read Fuel Tank Pressure Sensor Voltage Chart Your compression test numbers depend on which model 944 you have. Minimum readings on the compression gauge should be as follows: 944 Turbo - 120# 83-86 944 - 140# 87 - 88 944 - 150# 944S, S2 - 160# After a rebuild, your initial compression number should be less than your second compression test (just as you indicated). Compression Test Before performing the Engine Compression Test, check the battery. The battery must be fully charged, in good condition and properly connected. If the battery is not fully charged, recharge or replace it. Compression Gauge Check 1. Run the engine until it reaches normal operating temperature. 2. Turn the engine off. 3. Remove . Approximately 130-150 psi could be expected with a 9.5:1 compression ratio. . Running compression ratios above 10:1 on 87 octane gasoline may lead to knocking and reduced performance. Higher octane fuel is recommended for high compression ratios. . Do you have to remove all spark plugs for a compression test? Yes, it’s necessary to remove .
During the compression test, a compression tester is used to measure the pressure generated when the piston compresses the air-fuel mixture within the cylinder. This reading provides an indication of the engine’s ability to generate the required pressure for efficient combustion. . 10-150 ft/lb, 13.6-203.5 N/m. Through compression testing . Doing a compression test, is a good way to measure the condition of, the rings, cylinders, and valves. So, if your engine is running rough or is lacking power, consider doing a compression test. Also, it is important to perform a compression test every time a tune-up is done, as part of preventative maintenance. Number Crunching.
