1.	Which of the following results in a decrease in the scuffing near the sealing ring area?(a) Torque(b) Enthalpy(c) Engine speed(d) Running clearanceI have been asked this question in an online interview.My doubt is from Engine Components topic in chapter Basic Engine Components of Automotive Engine Design
Answer» Right option is (d) Running clearance Explanation: Scuffing near the sealing RING area leads to localized hardening of the ring, very HIGH pressure is EXERTED against the cylinder liner RESULTING in its DISTORTION so that running clearance is deceased and the scuffing occurs near the affected area.
