2. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths. Leak-down primarily tests pistons and rings, seated valve sealing, and the head gasket. Leak-down will not show valve timing and movement problems, or piston movement related sealing problems. Any test should include both compression and leak-down.

3. Compression ratio - Wikipedia

   en.wikipedia.org/wiki/Compression_ratio

   The static compression ratio discussed above — calculated solely based on the cylinder and combustion chamber volumes — does not take into account any gases entering or exiting the cylinder during the compression phase. In most automotive engines, the intake valve closure (which seals the cylinder) takes place during the compression phase ...

4. Twist compression tester - Wikipedia

   en.wikipedia.org/wiki/Twist_compression_tester

   The Twist Compression Tester ("TCT") is a hydraulically operated bench-top apparatus used to evaluate the level of friction and/or wear between two materials under lubricated or non-lubricated conditions. Under controlled conditions, a rotating annular specimen is brought into contact with a non-rotating flat specimen.

5. Compression release - Wikipedia

   en.wikipedia.org/wiki/Compression_release

   The most common kind of small engine compression release uses a camshaft mounted mechanical lever that pushes the exhaust valve tappet slightly, venting engine compression through the exhaust valve. Once the engine spins to starting speed, centrifugal force causes the lever to move out of the way, and the exhaust valve is allowed to seat fully.

6. OBD-II PIDs - Wikipedia

   en.wikipedia.org/wiki/OBD-II_PIDs

   OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
