\nAs Audi begins to roll out the A3 TDI to its U.S. dealers in the coming weeks<\/a> and the diesel version of the Q7 takes an ever larger share of sales, it’s time to celebrate. This Fall marks the 20th anniversary of the introduction of the first ever TDI engine. TDI, for the uninitiated, stands for turbocharged-direct-injection<\/em>, and refers to modern diesel engines from the Volkswagen group. Today’s TDI technology has evolved from the 20 year-old 2.5-liter five-cylinder in the Audi 100. <\/p>\n

Back then, the first TDI engines retained distributor type injector pumps, although the fuel was sprayed directly into the combustion chambers rather than a pre-chamber. Later, the company used something called Pumpe Düse – pump-injectors – for fuel delivery. This design integrated the high pressure pump and injector for each cylinder. These days, TDI uses common rail injection where a single pump pressurizes a single fuel rail that feeds all of the injectors. Regardless of the injector type, TDI has gone a long way towards improving the power output and reducing emissions of diesel engines. Audi and Volkswagen have built over five million TDI powerplants and remain committed to the technology. Congratulations on the double-decade milestone, guys.<\/p>\n
