1.	Which of the is caused due to excess of end gap?(a) Blow by and rapid wear(b) Scuffing and rapid wear(c) only rapid wear(d) Both blow bye and scuffingI had been asked this question in final exam.My question is from Engine Components in section Basic Engine Components of Automotive Engine Design
Answer» Right ANSWER is (d) Both blow bye and scuffing Best explanation: The amount of end gap has to be determined cautiously. Excessive end gap WOULD result in blow-by and scuffing of the ring. On the other hand,the lesser the CLEARANCE would cause the ring ends to BUTT at high temperature resulting in non-uniform PRESSURE.
