Is the compression ratio of a piston inside its cylinder measured mechanically or atmospherically?

Mechanically To put it as simply as possible. The cubic inches of a cylinder and the amount of space your compressing it into is the compression ratio.


Why does your car have bad compression?

Low Compression usually means that the cylinder rings are worn. You should also do a leak down of each cylinder. That will pinpoint which cylinder/s are bad. Also,possible poor seating of valves or improper valve seat contact.


Cylinder 5 misfire could it be the coil pack?

it's possible, also check compression, fuel supply, and vacuum leaks.


What does it mean if you do a compression check and there is no compression?

It just means that the railway is not compressed. Say that the railway was compressed, then you'd make a compression check and the answer would be positive, but if it isn't it means it's not compressed. When something is compressed, it means that the temperature was too cold for the railway so it compressed. Hope it helped! :P WHAT???? this person is lost. Ok, when you do a compression test and you receive no compression, make sure your test gage is a working gage. with no compression this indicates that exhaust / intake valves are in the open position which stops the cylinder from sealing for compression, possible bent or broken valve,valve spring,or lobe on cam may be worn. Now if you have a low compression reading on a cylinder i recommend you spray WD 40 into cylinder sparingly and test again,called a (wet test ) if compression raises you have bad piston rings, if it stays the same, its a valve issue, possible piston failure


What kind of battery do you need for a 1990 Toyota 4runner 4-cylinder 5sp?

What is the cylinder compression for 2.0 engine?

There is no real compression spec for the 2.0 zetec engine. Ford only says that no cylinder should be below 25% or all the cylinders. If it is that cylinder is down. That could be a number of problems such as head gasket or bad rings. Either way. Once you do a compression test yourself I would recommend having a dealership follow it up with a diagnostic. They will be able to give you solutions if there is low compression as far as possible reasons and repairs. Per. ALLDATA Ford NTI/ UTI student


Possible causes for over heating of 1994 Toyota 4-runner?

A compression check and cylinder leak-down test should tell you the condition of your engine.


Your 99 Explorer's service engine light keeps coming on It's always 4 cylinder misfire cold start changed wire and plug what gives?

Think a little deeper. Combustion that fails is a misfire. You have addressed the spark side of it. There is a fuel and compression possible trouble. Try swapping the fuel injector for that cylinder with another and see if the misfire moves to the other cylinder. Compression test the cylinder to see if it is in specs. Try a cylinder leak down test and see if it is losing compression. Perhaps there is a carbon build up on the valves preventing good seating?


What is the cylinder compression on a 1994 Isuzu trooper?

I'm not sure of the exact values; they should be in your Haynes repair manual. However, if you compression test all of the cylinders and find one that is lower you have a compression problem with that cylinder. It is also possible to have 2 that are lower, this would most likely indicate a warp in the head between those two cylinders. Other causes for compression loss are damaged or gunked up valves that do not close all the way or a crack in the head.
