Turbocharging technology enhances power output by recovering energy from exhaust gases emitted by the engine, with its core component being a coaxial system consisting of a turbine and a compressor. This increases the intake air density, enabling more complete fuel combustion, thereby significantly boosting power and torque without increasing engine displacement. Modern technologies such as the twin-turbo system optimize boost efficiency at different engine speeds through the coordinated operation of two turbines, while variable geometry turbine (VGT) technology maintains airflow velocity at low speeds by adjusting the angle of guide vanes, ensuring power response across the entire speed range. The twin-charging system combines mechanical supercharging and turbocharging: at low speeds, mechanical supercharging provides instant pressure, while at high speeds, turbocharging takes over, balancing smoothness and explosive power. When using a turbocharged engine, attention should be paid to selecting high-temperature-specific engine oil, shortening maintenance intervals, regularly cleaning turbo components, and replacing filters to avoid precision component wear caused by impurities. This technology not only improves performance but also optimizes fuel economy and reduces emissions, and is currently widely used in small-displacement high-efficiency engines such as 1.4T and 2.0T.
