What does TDI stand for?

TDI stands for Turbocharged Direct Injection and is a design of turbodiesel engines. It is developed and produced by the Volkswagen Group and characterized by turbocharging and cylinder-direct fuel injection.

TDI engines use direct injection, in which a fuel injector sprays atomized fuel into the primary combustion chamber of each of the cylinders. TDI diesel engines are known for being responsive, efficient and fun to drive. They have more power with high fuel economy, which aids in lowering emissions and minimizing its impact on the environment. TDI designs produce better performance with greater pulling power than that offered by the traditional fuel injection systems.
