DIRECT FUEL INJECTION – PART I
Common rail systems usually feature piezoelectric injectors, which ensure fuel metering and injection timing to the cylinders with great precision.
Underneath is the ignition coil rail that comprises of three coils (one for each cylinder). The cylinder head is cooled down with a specific hydraulic fluid traveling through the red-sealed carbon tube.
The airbox logically sits at the top, and we can also notice the white-sealed pipe that in all likelihood feeds compressed and cooled down air towards the air intake plenum chamber. In order to accommodate Red Bull’s split-intercooler design, an identical duct can be found at the same level but on the other side of the Renault power unit.
In all probability, the orange three-phase electric cable connects the MGU-H to the battery.
