What does TDI mean?
1 Answers
TDI stands for Turbocharged Direct Injection diesel engine. To address the shortcomings of naturally aspirated diesel engines, a turbocharging device is added to the diesel engine, significantly increasing the intake pressure and compression ratio, which allows for greater torque generation, more complete combustion, and stronger power output. Below are the relevant details: 1. Definition of Turbocharged Direct Injection diesel engine: A Turbocharged Direct Injection diesel engine is a diesel engine equipped with a turbocharging device, which greatly increases the intake pressure, with the compression ratio generally exceeding 10. This enables the engine to achieve high torque at very low speeds, and due to more complete combustion, the harmful particulate content in emissions is significantly reduced. 2. Function of the turbocharger: The turbocharger helps the engine increase air intake, making combustion in the cylinders more intense, thereby increasing the energy of piston movement and the overall power output of the engine. 3. Components of the turbocharger: The main body of a typical turbocharger consists of the turbine housing, turbine wheel, and compressor wheel. The auxiliary systems include an integrated electronically controlled wastegate, bypass valve assembly, dual cooling system, and intercooler assembly.
