Abstract
Embodiments of the present invention provide a pre-combustion chamber assembly, comprising (a) a body, having a cylindrical end portion having a step-wise increase in diameter forming a sealing surface for sealing to an engine; (b) a tip, with a hollow shaft in fluid communication with a combustion region of the tip, where the shaft has a first shaft diameter that allows the shaft to be slid over a portion of the body; (c) a gasket mounted about the body and resting against the sealing surface, wherein the gasket comprises a wire wound washer.
Claims13
A pre-combustion chamber assembly for use in an engine, wherein the engine defines a combustion chamber bounded in part by a cylinder head, with the head defining a coolant space separate from the combustion chamber, wherein the head has one more cylindrical holes extending from the coolant space to the combustion chamber, wherein the one or more holes have a first hole diameter facing the coolant space and a second hole diameter facing the combustion chamber, where the hole has a step-wise change in diameter from the first hole diameter to the second hole diameter at an axial location in between the coolant space and the combustion chamber, the pre-combustion chamber assembly comprising:
- (a) a body having a cylindrical end portion having a first portion with a first body diameter less than the first hole diameter and greater than the second hole diameter, and having a second portion with a second body diameter lesser than the second hole diameter, where the body has a step-wise change in diameter from the first body diameter to the second body diameter forming a shelf;
- (b) a tip that fits over the body, having a maximum diameter less than the second hole diameter, configured to be placed in communication with the combustion chamber;
- (c) a gasket having an inner diameter greater than the second body diameter and lesser than the first body diameter, and having an outer diameter lesser than the first hole diameter;
- mounted with the body around the first portion and adjacent the shelf;
- wherein the gasket comprises a wire wound washer.
