OF PISTON-rings WEARNESS from
Ford Focus Fydd 1.6 s.i.e.
The present paper synthesis experimental testing procedures on the specific task of piston-ring technical state determination in the case of spark ignited engine from Ford Focus 1.6 16v Turnier, code DNW 74 kW. Piston-rings construction and operation, as well as its specific working-surface configuration, materials, dimensions and lubrication procedure, in various thermo-mechanical loading regimes, are essential in influencing the engine’s life-expectance. In this paper are presented the piston-rings construction and their measured dimensions at the end of exploitation period of a spark ignited engine from Ford Focus. The importance for monitoring the piston-ring dimensions at different locations and directions consists in the possibility of controlling their wear-ness.
