Injector assembly

An injector assembly adapted for use in an internal combustion engine including a cylinder block defining a bore having a cylinder liner therein defining a cylinder bore, a cylinder head attached to the cylinder block in closing relation to the cylinder bore and having upper and lower walls partially defining a cooling liquid jacket portion, a piston reciprocally mounted in the cylinder bore and defining with the cylinder liner a variable volume combustion chamber, a pair of axially aligned openings through the upper and lower walls with the opening through the lower wall communicating with the combustion chamber and including a bore, an annular shoulder generally facing the cooling liquid jacket portion, and a frusto-conical portion converging outwardly from the annular shoulder towards the combustion chamber, comprising:

• a non-deformable injector sleeve having a lower annular surface seating against the annular shoulder when in use and an upper annular surface opposite the lower annular surface, the injector sleeve when in use disposed at least partially in the upper and the lower wall openings and extending through the cooling liquid jacket portion;
• an injector cone including a lower portion extending through the injector sleeve and an upper portion having a top surface and a bottom surface adjacent the upper annular surface of the injector sleeve;
• and
• a fuel injector extending through the injector cone and adapted for connection with the cylinder head when in use and including a connecting portion connected to the upper portion of the injector cone.
