Direct fuel injection (DFI) Panamera GTS

Porsche Panamera GTS - Direct fuel injection (DFI)

Direct fuel injection (DFI)

With millisecond precision, DFI injects fuel at up to 120 bar directly into the combustion chamber by means of electromagnetically actuated injection valves. DFI also improves the internal cooling of the combustion chamber by having the mixture prepared directly in the cylinder. The higher compression ratio helps to deliver more output at the same time as enhanced engine efficiency.
