The primary function of piston compression rings is to seal the combustion chamber from adverse effects of power loss and blow-by. This requirement can affect friction, reduction of which is another key driver in engine design. The parasitic losses of compression rings can account for 7-9% of fuel energy expended. Some of these losses are due to complex ring elastodynamic behaviour, which can also result in loss of sealing. Loss of power due to poor sealing itself can account for a significant parasitic loss and lead to unacceptable emissions. Progressively, industry is subjected to rigorous directives with regard to emissions above prescribed limits and fined according to a sliding scale above this limit. The aim of research is to combine ring modal behaviour with elastohydrodynamic analysis and a gas flow model. The objective is to carry out parametric studies for optimisation of ring geometry, topography and material of construction in order to arrive at optimal compression ring design.
