What does TD mean in cars?
1 Answers
TD in cars stands for turbocharging. To address the inherent shortcomings of SDI, a turbocharging device is installed on diesel engines, significantly increasing the intake pressure. The compression ratio generally exceeds 10, allowing for high torque even at low RPMs. Moreover, due to more complete combustion, the content of harmful particles in emissions is also reduced. The TDI-equipped direct-injection turbocharged diesel engine technology is highly advanced and incorporates multiple cutting-edge technologies, such as the pump-jet system and adjustable vane turbochargers, which are applied in passenger cars. TDI utilizes high-pressure fuel injection technology with a pump-jet system. This system ensures better mixing of diesel and air, leading to more thorough combustion.
