A way to reduce Hydrocarbon emissions of IC engines is the focused reduction of lube oil consumption within the lubricated contact between the piston group and the liner surface and the blowby of exhaust gases into the crankcase.

The investigation and optimization of this components can’t be done by splitting the mechanic and thermodynamic peculiarities of it, as it has been done up to now.

A coupled investigation of the system dynamics and the flow-dynamics of the gasses and the oil has to be performed. This paper displays the potentials which are available by coupling AVL EXCITE and AVL FIRE for an optimized piston group layout.
