Summary:

An innovative two-piece oil control ring design, named Monoland, has been developed aiming to have high conformability and optimized specific contact pressure. As a result, the Monoland provides superior oil scraping efficiency with reduced friction losses. These were achieved by tailoring the geometrical features and material properties.A solution for oil control rings of minor moment of inertia and higher conformability was achieved through a new geometrical design concept where: a) only one land of the ring is in contact with the bore, b) the outer and inner faces are linked by two convergent planes and by means of a Powder Metallurgy (P/M) steel that was tailored to a lower modulus of elasticity.The new ring design had its structural robustness checked by finite element analysis and its scraping capacity measured by lubricant oil consumption measurement in engine tests
