摘要

It is well known that the transportation industry is partly responsible for the CO_2 emissions. Particularly involved in this field are personal cars because of their increasing number. So the European Community has fixed through its institutions very ambitious objectives of reduction of fuel consumption for the automotive industry. These objectives have been taken into account by car manufacturers and consequently more power has been focused on fuel consumption reduction, mainly through engine design and management. The subject of this paper will address the efforts in fuel economy in engines resulting of the reduction of the friction level of mechanical parts. As a major part of the friction losses are concentrated in the piston assembly system in an engine, these mechanical parts have been chosen as an efficient illustrative example. The purpose of the present work is to emphasise the role of the experimental set-ups in understanding the friction laws in an industrial example. Firstly it will be shown how it is possible, from physical measurements coming from a complete mechanical experimental device, to verify well-known friction laws. In a second step as the friction conditions are understood, the effect of some parameter variations on the friction force in the complete piston ring-cylinder liner system will be outlined.
