prior to the spark plug igniting it. It causes the piston to smash into the expanding gas and the pressure can be staggering. Compression causes a lot of heat and turbos greatly increase both. Higher octane fuel help reduce the likelyhood of pre-ignition or knocking. It works great in Diesel engines who rely on compression heat to ignite the fuel, thus their extremely high compression rations and lack of spark plugs.
