Direct diesel injection (TDI)
On an engine with direct diesel injection, the fuel is injected directly into the combustion chamber at a pressure which sometimes exceeds 2,000 bar. TDI engines are extremely efficient and therefore offer maximum fuel economy. Under the name of EA288 evo, Volkswagen has just developed a new generation of four-cylinder diesel engines (TDI). They not only comply with the current limits of the EU6d-temp exhaust emission standard, but are also already prepared for the future EU6d standard (which applies to new models from September 2019).
