Abstract
An improved injector cup may be used in diesel engines that fits more securely into the engine's cylinder heads to better prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant. An improved injector cup may be designed to accommodate specific engine types and sizes in order to prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant.
Claims18
A method for preventing leakage of coolant in a diesel engine, comprising:
- providing an injector cup comprising a barrel having threads at a distal end and at least two O-rings near a proximal end, wherein the barrel does not include a conical portion;
- inserting the injector cup into an injector cavity bore of a cylinder head, wherein the cylinder head comprises insertion threads at the bottom of the cylinder head;
- and
- tightening the injector cup into the injector cavity bore via engagement between the insertion threads and the threads of the injector cup in a manner that prevents floating of the injector cup within the cylinder head and in a manner that enables the O-rings to engage an injector cavity wall.
A method for installing an injector cup into a diesel engine, comprising:
- providing an injector cup, wherein the injector cup comprises threads at a distal end, at least two O-rings near a proximal end, and a barrel having a consistent diameter;
- inserting the injector cup into an injector cavity bore of a cylinder head, wherein the cylinder head comprises insertion threads at the bottom of the cylinder head;
- tightening the injector cup into the injector cavity bore via engagement between the insertion threads and the threads of the injector cup in a manner that prevents floating of the injector cup within the cylinder head and in a manner that enables the O-rings to engage an injector cavity wall;
- creating a seal between the injector cavity bore and a coolant chamber, wherein the seal is created by the engagement of the O-rings with the injector cavity wall and the seal prevents leakage of coolant in the fuel of the diesel engine and prevents leakage of fuel into the coolant of the diesel engine and;
- cutting a recession into the injector cup.
A method for preventing leakage past an injector cup of a diesel engine, comprising:
- providing an injector cup, wherein the injector cup comprises a barrel having threads at a distal end, at least two O-rings near a proximal end, and a plurality of cavities near the proximal end of the injector cup, wherein the barrel does not have a conical portion;
- inserting the injector cup into an injector cavity bore of a cylinder head, wherein the cylinder head comprises insertion threads in a fire deck side of the cylinder head;
- providing a torque tool having a plurality of prongs at one end, wherein the plurality of prongs are configured to engage the plurality of cavities in the injector cup;
- inserting the plurality of prongs into the plurality of cavities;
- engaging, properly, the threads of the injector cup with the insertion threads;
- tightening the injector cup into the fire deck side of the cylinder head via the engagement between the insertion threads and the threads of the injector cup in a manner that prevents floating of the injector cup within the cylinder head and in a manner that enables the O-rings to engage an injector cavity wall.
