1.	Which among the following is not a function of the piston rings?(a) To seal the high-pressure gases(b) Easy passage for the heat to flow from crown to cylinder(c) Maintain sufficient lubrication(d) Helps in detonationI had been asked this question in unit test.The question is from Engine Components in chapter Basic Engine Components of Automotive Engine Design
Answer» Right choice is (b) EASY passage for the heat to flow from crown to CYLINDER To EXPLAIN I would say: The PISTON ring should seal for the high-pressure gases from the combustion CHAMBER, should provide easy passage for heat flow from the piston to the crown,should maintain sufficient lubricating oil on cylinder walls throughout and should not help is detonation.
