o A turbo charger is a device that uses the energy of exhaust gases coming out from an engine to compress the air going into the engine. It must have at least 4 openings: 1 for the engine exhaust gas to enter; a 2nd for the exhaust gas to exit; a 3rd opening for intake air to enter the turbocharger; and a 4th for the intake air to exit the turbo charger on its way to the engine intake. A turbo charger will also have 1 additional opening to vent excess air pressure. Increasing the intake air pressure going into an engine can increase the engine's power, but too much air pressure can damage the engine. Increasing the pressure increases the power of the engine because of the increased density of the air. Increased air density means more oxygen molecules, which means the engine can respond by increasing the amount of fuel it mixes with that oxygen.
