Under pressure: Low tension piston rings

In order to reduce frictional drag, energy loss and increase fuel efficiency, gasoline direct injection (GDI) engines use thinner and lighter piston rings, called low-tension piston rings. Piston ring spring force in older port fuel injection (PFI) engines used to be as high as 30 psi. New PFI and GDI engines can have more than 60 percent reduction in sealing pressure on the cylinder walls.
