Steel pistons for diesel commercial vehicles

Our steel pistons for commercial vehicle diesel engines reduce fuel consumption more than aluminium pistons , even when the weight is the same or less. They also have a lower compression height to allow use of a longer connecting rod for further frictional performance advantages. This advantage can also be used for
a more compact engine design, reducing vehicle weight.
