Abstract

The height of a piston for an internal combustion engine is reduced by the provision of gudgeon pin bores which intersect or at least partly intersect a ring band extending around the crown. This allows the mass of the piston to be reduced and allows improved visibility from the vehicle owing to reduced bonnet height. The weight of the piston is reduced so improving its performance and the performance of the engine.
