摘要： A piston (17) for an internal combustion engine. The piston (17) has a piston head (43) and a recess (46) formed in the piston head. A formation (91) is associated with the recess (46) for generating a turbulent motion in a fluid introduced into the recess. The formation (91) is configured to generate a swirling turbulent motion to the fluid introduced into the recess and preferably comprises spiral grooves (93) formed in the piston.

摘要： A combustion chamber assembly for use in a piston of a diesel engine includes a combustion chamber being defined in a crown of a piston, the combustion chamber having a center portion, the center portion being defined at least in part by a surface being a portion of a convex sphere to define a post, the sphere having a radius and an origin, the origin of the radius lying on a combustion chamber central axis and the combustion chamber further having an outwardly radially disposed sidewall margin, the sidewall margin being defined in part by an annular surface, the annular surface being concave and having an origin and a radius. The combustion chamber is further defined by an annular bowl lip surface. A piston and a method of forming a combustion chamber are further included.
