Turbochargers are forced induction devices utilizing exhaust gas energy to compress intake air, increasing engine power and efficiency. Typically employed on gasoline and diesel engines, they consist of a turbine and compressor connected by a rotating shaft. Key components include a volute, turbine wheel, compressor wheel, and often an integrated wastegate or variable nozzle turbine (VNT) for boost control. Modern turbochargers frequently incorporate ball bearing or journal bearing construction, and may feature electronic boost control actuators. Intercooling is commonly paired with turbocharger systems to further enhance performance and reduce temperatures.
