Description:UNIT PUMP FOR AN INTERNAL COMBUSTION ENGINE

FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a pumping system, and in particular, to a unit pump for an internal combustion engine.

BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] Unit pumps are high-pressure fuel delivery devices widely used in diesel engines, particularly for the accurate and efficient injection of fuel into the engine cylinders. In larger engines, multiple unit pumps are typically used to supply fuel to each cylinder indepe , Claims:We Claim:
1. A unit pump (100) for an internal combustion engine (102), the unit pump (100) comprising:
at least one camshaft functionally coupled to a crankshaft of the engine (102), wherein the at least one camshaft (106) is configured to rotate along with rotation of the crankshaft and has a predefined drive ratio;
at least one cam profile (108) positioned along the at least one camshaft (106), wherein the at least one cam profile (108) is configured to rotate along the at least one camshaft (106), wherein the at least one cam profile (108) comprises a predefined plurality of lobes; and
at least one plunger (112) integrated within a fuel barrel of the unit pump (100), wherein the at least one plunger (112) reciprocates within the fuel barrel to deliver fuel, as a corresponding lobe of the predefined plurality of lobes (110) pushes the at least one plunger (112);
wherein each of the plurality of lobes (110) is configured to have a predefined lift height at which the corresponding lobe pushes the at least on
