Abstract: It is clear that today fuel economy and reliability stand high in the priority rating of most automotive manufacturers| programmes. The piston has a contribution to make in both areas. This paper examines various piston features in relation to fuel economy, including weight, friction, top ring location and crown insulation. Reliability is considered with respect to piston strength, including the boss and crown regions, and squeeze casting is presented as offering a major technical step forward, particularly when combined with local fibre reinforcement.

Keywords: aeconoguide pistons; composite materials; fibre-reinforced pistons; fuel consumption; lightweight piston design; piston friction reduction; piston strength; reliability; squeeze-cast pistons; vehicle design.
