So a small release of pressure to cause a decompression helps. READ ALSO: An insight Of Engine ValvetrainĪnother main use of decompressor is during kick starts, the low compression allows the rider to kick the engine easily else if the compression was too much, then the reverse action to the kick start would be too high and could even injure the rider. So to take care of that problem, one of the exit valve is designed in such a way as to open a little bit to allow some more breathing space and let the compression level fall a bit and the engine can start up properly. So if this compression exceeds the level that the bike is designed for, then there are chances of the engine to burst altogether and that is very much fatal. So when the starter is applied, more air and fuel mixture enters inside the combustion chamber and causes extra compression than required. During the first start there is already pressure buildup due to end of the engine running in the previous cycle of running. This is generally needed at certain times like during the initial ignition of the engine start up. You reduce the compression or the pressure inside the chamber for everything to work well.

This compression causes spike in the pressure that helps in the quick ignition. That number is actually the rate of compression where the area that 1 unit takes up, in the same area 8 units now acquire.
If you check out the specs of any bike, you will notice a column that reads compression and that reads anywhere from 8:1 up to 14:1. This pressure is created due to the compression in the combustion chamber by the piston. But in the entire process there is one more thing that helps in the process and that is pressure. In any internal combustion engine, the fuel and air mixture gets ignited and power is generated.
