Volkswagen continues to stay at the forefront of innovative engineering, especially as it relates to their diesel engines. The newest of these innovations in the great line of Volkswagen automobiles is to add TDI to the engine, but what is TDI?
TDI is the acronym for Turbocharged Direct Injection and meant for the diesel engines of Volkswagen to allow both turbocharging and cylinder-direct fuel injection. The main difference from the older diesel engines is the direct injection part of the TDI format. In older model diesel engines the fuel is sprayed in to a pre-combustion chamber rather than directly into the main combustion chamber, which is what the TDI format delivers.
