As fuel efficiency improves, reduced weight and a decrease in mechanical loss for engines have become important issues to be solved. In order to reduce friction loss around pistons that accounts roughly for 40-50% of friction loss in the entire engine, narrower-width piston rings that are compatible with smaller pistons and the use of low-tension piston rings are becoming widespread.
