Abstract
A piston (8A, 8B) for a hydrogen-powered internal combustion engine (7) including a piston head (11), a piston skirt (10) connected to the piston head (11), and a combustion bowl (24) provided on the piston head (11). The piston (8A, 8B) has a piston diameter (32) that can be measured on the piston skirt (10), wherein the combustion bowl (24) has a minimum combustion bowl volume (29) amount of 2.9674 times the amount of the piston diameter (32) minus a value of −220.68, and wherein the combustion bowl (24) has a maximum combustion bowl volume (29) amount of 4.1893 times the amount of the piston diameter (32) minus a value of −311.55. Also disclosed is a hydrogen-powered internal combustion engine including the piston.
Claims19
A piston for a hydrogen-powered internal combustion engine comprising:
- a piston head;
- a piston skirt connected to the piston head ;
- and
- a combustion bowl provided on the piston head;
- wherein the piston has a piston diameter measured on the piston skirt,
- wherein the combustion bowl has a minimum combustion bowl volume which is 2.9674 times the piston diameter minus a value of 220.68, and
- wherein the combustion bowl has a maximum combustion bowl volume which is 4.1893 times the piston diameter minus a value of 311.55.
A piston for use in a hydrogen-powered internal combustion engine, comprising:
- a piston head comprising:
- a center axis;
- a fire bridge having an upper surface positioned on a plane oriented perpendicular to the center axis;
- and
- a combustion bowl defined by the plane and an edge-free combustion bowl surface extending radially outward from the center axis to the fire bridge at the upper surface;
- and
- a piston skirt connected to the piston head, the piston having a piston diameter measured on the piston skirt,
- wherein the combustion bowl has a combustion bowl volume configured to have between a minimum combustion bowl volume which is 2.9674 times the piston diameter minus a value of 220.68, and a maximum combustion bowl volume which is 4.1893 times the piston diameter minus a value of 311.55.
