Where are the piston rings located on a small engine? Piston rings commonly used on small engines include the compression ring, wiper ring, and oil ring. A compression ring is the piston ring located in the ring groove closest to the piston head. What causes a piston to pull on a ring gap? “The increased force to the cylinders starts to hold the piston tighter to the cylinder wall,” DiBlasi explains. “This added resistance, in conjunction with heat starts to soften the piston. It first will start to pull on the ring grooves and lands, spacing them further and further...
