UEM Pistons Releases New Dualoy Diesel Pistons

New Dualoy Diesel Pistons are made from two alloys, an aluminum casting with an iron top ring carrier bonded in. Diesel engines are notorious for the extreme pressures exerted on the top ring, according to UEM, so the company says its design gives the top ring a much harder surface on which to operate.
