  • Page 15: Crankshaft/Crankshaft Bearings

    Boxster Boxster S Cayman Cayman S Crankshaft/crankshaft bearings The drop-forged crankshaft runs on eight bearings and has twelve counterweights. Main bearing 4 is designed as a thrust bearing. Axial play is determined by two Engine thrust plates, which are inserted at the left and right of the bearing. The main bearings are designed as plain bearings with a diameter of 63 mm.

    Boxster Boxster S Cayman Cayman S Connecting rods The connecting rods (6) are forged and are split (cracked) at the big end following Engine machining. Both parts are aligned with one another via the fractured surface. Although a matching number is not needed for cracked connecting rods because of the fact that each fractured surface has a different shape, matching numbers are used here to ensure process reliability.

  • Page 17: Pistons

    Boxster Boxster S Cayman Cayman S Pistons The pistons on the new Boxster and Cayman models are forged from a light alloy. Since mixture formation is different on the basic models and the S version, the Engine piston shape is also different. Mixture formation and the direct fuel injection (DFI) combustion process require a special piston crown shape.

  • Page 20: Cylinder Head

    Boxster Boxster S Cayman Cayman S Cylinder head The cylinder heads in the new engines are designed as a single piece without a Engine separate housing for the hydraulic bucket tappets. It was possible to reduce the weight of the new cylinder heads compared to the previous models (two-piece cylinder heads with a separate bucket tappet guide housing) by using an improved casting process.
  • Page 21 Boxster Boxster S Cayman Cayman S Cylinder-head gasket To ensure the excellent sealing quality of the surface of the multi-layer steel seal, it is covered with high temperature-resistant plastic. The advantage of this steel seal Engine is that the heat can be conducted very well away from the cylinder head.

  • Page 28 Boxster Boxster S Cayman Cayman S Function Depending on the input values for engine speed, engine load, engine oil tempera- Engine ture and the expected change in engine speed, a specific control valve (4) position is defined using a map in the DME control unit. The control valve position regulates the oil pressure for the spring piston on the gear wheel, which can move in axial direction.

  • Page 29: Cooling

    Boxster Boxster S Cayman Cayman S Cooling The cooling concept is an enhancement based on the effective cylinder head cross- flow cooling used on previous models and was developed to selectively cool the hot Engine spots in the cylinder head and crankcase. The design and position of the new coolant pump as well as the revamped internal engine cooling ducts in particular in the cylinder head are new.
  • Page 30 Boxster Boxster S Cayman Cayman S The greater engine power has resulted in a greater cooling requirement in the area of the cylinder head.

  • Page 47: High-Pressure Fuel System

    Boxster Boxster S Cayman Cayman S Fuel high-pressure system in DFI flat engines The fuel high-pressure system generates the injection pressure of 580 to 1740 psi (40 to 120 bar). The fuel is distributed to the high-pressure injectors by the high- Fuel and ignition system pressure pump via the high-pressure lines to the fuel rails of cylinder banks 1 and 2.
