What does turbocharging in cars mean?
1 Answers
Turbocharging, abbreviated as Turbo, is indicated by the presence of 'Turbo' or 'T' on the rear of a car, signifying that the vehicle is equipped with a turbocharged engine. A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of the exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then compresses the air delivered through the air filter pipeline, pressurizing it before it enters the cylinders. The following points should be noted during use: 1. Do not drive immediately after starting: After starting the engine, allow it to idle for a period to ensure that the lubricating oil fully lubricates the bearings before the turbocharger rotor operates at high speed. Avoid revving the engine aggressively right after starting to prevent damage to the turbocharger oil seal. 2. Do not shut off the engine immediately: After prolonged high-speed operation, the engine should not be turned off immediately. During operation, part of the engine oil is supplied to the turbocharger rotor bearings for lubrication and cooling. If the engine is suddenly stopped while running, the oil pressure drops rapidly to zero, and the high temperature from the turbocharger turbine transfers to the middle, while the heat in the bearing support housing cannot dissipate quickly. Meanwhile, the turbocharger rotor continues to spin at high speed due to inertia. Therefore, after heavy or prolonged operation, the engine should idle before shutting off. 3. Reduce RPM before shutting off: Allow the turbocharger rotor speed to decrease before turning off the engine. Special care should be taken to avoid shutting off the engine suddenly after revving it aggressively. 4. Regular cleaning: Since the turbocharger often operates at high temperatures, the lubricating oil lines are prone to coking due to the heat. Regular cleaning is necessary.
