Direct fuel injection (DFI) Macan Turbo

Porsche Macan Turbo - Direct fuel injection (DFI)

Direct fuel injection (DFI)

With millisecond precision, DFI injects fuel at up to 200 bar directly into the combustion chamber by means of electromagnetically actuated injection valves. The spray and cone angles have been optimised for torque, power output, fuel consumption and emissions by enabling a homogeneous distribution of the air/fuel mixture and, therefore, effective combustion. 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.
