Direct fuel injection (DFI) Cayman

Porsche Cayman - Direct fuel injection (DFI)

Direct fuel injection (DFI)

Direct fuel injection (DFI) is featured as standard in the Cayman models. Multi-hole injectors deliver fuel directly into the combustion chamber with millisecond precision. DFI improves the internal cooling of the combustion chamber by having the mixture prepared directly in the cylinder. This allows for a higher compression ratio, which helps to deliver greater power output at the same time as enhanced engine efficiency.
