Opposed piston three nozzle piston bowl design

A piston comprising:

• an outer peripheral surface having first and second openings spaced about and extending through the outer peripheral surface;
• and
• a crown having a first recess at least partially defined by a first lobe in fluid communication with the first opening, the first lobe having a first centerline, and a second lobe in fluid communication with the second opening, the second lobe having a second centerline, each of the first and second lobes being recessed relative to an adjacent portion of the first recess of the crown, wherein:
• the first recess has a substantially hemispherical shape and is symmetrically disposed about a longitudinal axis of the piston;
• the first lobe includes a first flank surface, a second flank surface, a first side surface, a second side surface, the first and second flank surfaces extending along the first centerline in a first direction from the first opening to the first and second side surfaces, respectively, and being angled away from the first centerline in the first direction, the first and second side surfaces being angled toward the first centerline in the first direction;
• and
• the second lobe includes a third flank surface, a fourth flank surface, a third side surface, and a fourth side surface, the third and fourth flank surfaces extending along the second centerline in a second direction from the second opening to the third and fourth side surfaces, respectively, and being angled away from the second centerline in the second direction, the third and fourth side surfaces being angled toward the second centerline in the second direction.
