TDI

At Volkswagen, TDI identifies diesel-powered models with direct injection and a turbocharger. Characteristic features of the TDI engines are fuel economy, high pulling power (torque) and outstanding power efficiency. TDI is a registered trademark of Volkswagen AG in many countries.

The operating principle: a turbocharger supplies the engine with fresh air, thereby providing optimum cylinder charging. After compression, the diesel fuel is injected directly into the cylinders at very high pressure through a nozzle. The effective engine encapsulation keeps furthermore noise to a minimum.
