Pistons

Pistons

The pistons are designed as recessed pistons made of aluminum alloy. They have a graphite friction coating at the sides to improve friction performance of the piston. The pistons are different for cylinder bank 1 and cylinder bank 2. The valve recesses and combustion chamber troughs are arranged differently. The position and shape of the piston recess allows the injected fuel to be whirled around and mixed with the air that is drawn in.
