Fuel-saving potential of the commercial vehicle steel piston

Steel pistons have been used successfully in commercial vehicle for several years now. They became necessary because manufacturers wanted to fulfill the various stages of emissions legislation with measures inside the engine for as long as possible as power density increased. Consequently, peak cylinder pressures of over 220 bar can sometimes act on the piston, making the use of high-strength steel designs inevitable. New ways to make these pistons even more efficient are now being sought.
