pounds of compression per cylinder
Compression is normally expressed in terms of pounds per square inch (PSI),...foot lbs would relate to twisting forces such as a spinning crank shaft. Two different animals.
a strong engine should read between 150 and 180 pounds of pressure in each cylinder.
The pressure in a petrol engine cylinder can vary depending on the engine design, operating conditions, and performance parameters. Generally, during the compression stroke, the pressure can reach around 150-200 psi (pounds per square inch) before ignition, and peak pressures of 600-900 psi can be achieved during combustion.
factory recomeded compression ratio in foot pounds for a 1993 Chevrolet s10 truck with a 2.8 engine? Compression ratio in a vehicle usually refers to the difference of cylinder displacement at top dead center versus bottom dead center. For example: if the volume is 1 cubic inch at the top of the piston stroke and 10 cubic inches at the bottom of the piston stroke, 1/10=10:1 compression ratio (or is it 9:1? Close enough for government work.) Foot pounds is a measurement of torque. The two most common measurements of torque on a vehicle is either the twisting force exerted by a vehicle's engine (torque/hp engine specs) or how tight a bolt is supposed to be turned (lb/ft of torque specs for a bolt). Other than the fact that compression ratio and foot pounds may be used to describe a vehicle's engine attributes, they have nothing else in common.
thats a little on the worn engine side of compression,but that in itself would not keep it from starting....most likely a fuel or spark problem. you can check fuel pressure with a screw in guage from autozone,and check spark with an inline spark tester from autozone.
The compression readings will vary with wear from one engine to the next. What you want to see is that all the cylinder readings are within 10 to 15% between the highest and lowest. If one or more cylinders have a reading well below the average of the others, the engine is probably tired and in need of overhaul.
The compression for a 1996 Arctic Cat 440 snowmobile typically ranges from 120 to 130 psi (pounds per square inch) when the engine is in good condition. It's important to check the manufacturer's specifications for your specific model and ensure the engine is properly warmed up and using the correct testing procedures for accurate readings. If the compression is significantly below this range, it may indicate issues such as worn piston rings or cylinder damage. Regular maintenance can help keep the engine in optimal condition.
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.
