Piston assemblies and power cell modules

The growing success of MAHLE piston assemblies and power cell modules (PCU) for gasoline and diesel engines is in close tandem with its global presence as a system supplier. As early as the nineties, the first series production orders were placed for a power cell module - consisting of piston, rings, pin, connecting rod, and bearings. The first high volume production orders then followed in 2001. In 2007, more than eight million PCUs are produced.





Complete modules
With the "power cell unit" consisting of piston with rings and pin, cylinder liner and connecting rod with bearings, MAHLE provides a system which offers the customer economic and logistical advantages on account of its simplified assembly and perfected design.

Shorter development times
In contrast to individual components, power cell modules are developed as a complete system. Precise simulation results contribute to a reduction in the blow-by, oil consumption and wear. Cylinder deformations and piston transverse movement - the main parameters for piston acoustics and potential cavitation problems in the combustion chamber - have already been optimized in the development phase under consideration of all interactions. The integration of development activities at MAHLE leads to a reduction in the respective development phases, development times and, as a result, the development costs for the customer as well.

Supplied just in time
The preassembly of components at MAHLE relieves the customer of certain complex workflows. The modules are supplied "just in time".
