GASOLINE OIL – OCTANE
Octane is a hydrocarbon liquid that is used as a reference standard to describe the tendency of gasoline, petrol, or benzin fuels to self-ignite during compression prior to the desired position of the piston in the cylinder as appropriate for valve and ignition timing. The problem of premature ignition is referred to as pre-ignition and also as engine knock, which is a sound that is made when the fuel ignites too early in the compression stroke.
