The Fuel Injection Pump is a mechanical device that introduces fuel into automotive engine cylinders. It functions as the heart of a diesel engine, keeping the engine running smoothly for years. Furthermore, it is in charge of controlling the fuel flow in order to achieve the desired power. Traditionally, the Fuel Injection Pump is driven indirectly from the crankshaft by gears, belts, and chains, or anything that drives camshafts. It controls the timing of fuel injection, ignition, and combustion until maximum combustion pressure is reached. It modifies the amount of fuel.
