He has made significant contributions to the field of diesel engine technology, particularly through his innovative designs in piston structures. With a total of 2 patents to his name, Griffiths continues to push the boundaries of engineering.

Latest Patents

One of Griffiths' latest patents is the Dual Gallery Piston. This heavy-duty diesel piston features upper and lower portions that are joined across a friction weld. The piston is internally contoured to provide a dual gallery structure, which includes an outer annular gallery and a central gallery. These galleries are interconnected by passages that facilitate the communication of cooling oil between them. The design allows oil to enter from the outer gallery, formed by a circumferential annular recess in the crown and crown bottom, into the central gallery. This cooling mechanism is particularly effective for the central crown region, which is exposed to hot combustion gases. The friction weld not only provides high structural integrity but also minimizes the number of manufacturing steps required to attach the crown to the crown bottom.
