What Causes No Cylinder Compression?
2 Answers
No cylinder compression can result from the following reasons: 1. Poor valve sealing. 2. Cylinder leakage. 3. Incorrect valve timing. The impacts of no cylinder compression are as follows: 1. Engine damage: Issues with the ignition system and fuel injection system can lead to problems with spark plugs, ignition wires, and fuel injectors, causing poor ignition. If the issue stems from poor valve sealing, rocker arm detachment, valve deformation, or abnormal wear of piston rings and cylinder walls (such as scratches or deformed oil control rings), prolonged use may damage the engine. 2. Affects combustion: Insufficient cylinder compression negatively impacts combustion, resulting in reduced power and torque. If caused by piston sealing issues, it can also lead to severe carbon buildup in the combustion chamber and poor emissions.
As an automotive enthusiast, I often research engine issues. No cylinder compression means the engine cylinder has lost compression force, usually due to valves not sealing properly or getting stuck, which could be caused by excessive carbon buildup or worn valve seats. Another common problem is damaged or broken piston rings, allowing compression to leak through the gaps. A blown head gasket can also cause pressure loss. If the timing chain skips a tooth, the valves and pistons become out of sync, leading to compression failure. During diagnosis, I use a compression tester to measure pressure. If a cylinder shows zero or low readings, a leak-down test may be needed to locate the leak point. I once helped a neighbor fix their car and found it was a piston ring issue - replacing them restored normal operation. Don't delay repairs, otherwise the engine may fail to start or even suffer internal component damage, with drastically increased fuel consumption. I recommend taking it to a professional repair shop for comprehensive inspection - spending some time and money on proper repairs is worth it.
