is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed. With regard to modern automotive turbochargers, the need for a turbo timer can be eliminated by simply ensuring the car does not produce any 'boost' (during driving) for several minutes prior to the ignition being shut off. Most turbo timers are based on digital electronics. Turbo timers can usually be disabled by an external switch, this is normally done using the handbrake switch, or using an automatic one.
