Abstract
Official abstract text for this publication.
A pre-chamber assembly for an engine having a cylinder head defining a coolant passage is provided. The pre-chamber assembly includes a body member defining pre-combustion chamber received within the cylinder head, and a plurality of fins projecting radially from an outer surface of the body member. The plurality of fins includes a first set of fins proximate to the pre-combustion chamber, a second set of fins spaced apart from the first set of fins along a longitudinal axis, and a third set of fins disposed between the first set of fins and the second set of fins. A number of fins of the first set of fins is greater than a number of fins of the third set of fins, and the number of fins of the third set of fins is greater than a number of fins of the second set of fins.
First claim
Opening claim text (preview).
What is claimed is: 1 . A pre-chamber assembly for an engine having a cylinder head defining a coolant passage therein, the pre-chamber assembly comprising: a body member received within the cylinder head, the body member having an inner surface and an outer surface facing the coolant passage of the cylinder head, the body member defining a pre-combustion chamber at an end portion thereof, wherein the pre-combustion chamber is in communication with a main combustion chamber of the engine through at least one orifice; and a plurality of fins projecting radially from the outer surface of the body member, the plurality of fins being in contact with coolant received within the coolant passage of the cylinder head, each fin of the plurality of fins extends along a longitudinal axis of the body member, wherein the plurality of fins are positioned along the longitudinal axis of the body member in a predetermined pattern, the plurality of fins including: a first set of fins provided on the outer surface of the body member and proximate to the pre-combustion chamber defined at the end portion of the body member; a second set of fins provided on the outer surface of the body member and spaced apart from the first set of fins along the longitudinal axis; and a third set of fins provided on the outer surface of the body member and disposed between the first set of fins and the second set of fins, wherein a number of fins of the first set of fins is greater than a number of fins of the third set of fins, and the number of fins of the third set of fins is greater than a number of fins of the second set of fins.
