The injection pump is a mechanical device designed to deliver the exact amount of fuel to the engine cylinders at the precise time . This component is essential to ensure that the engine runs efficiently and at maximum power.
The main function of the injection pump in machines is to inject fuel at high pressure into the engine cylinders . This process must be carried out precisely to ensure efficient fuel combustion, which in turn maximizes engine power and minimizes fuel consumption. In addition, correct fuel injection reduces polluting emissions, contributing to more environmentally friendly operation.
The injection pump operates on the principle of high pressure fuel injection. The fuel, stored in a tank, is sucked into the pump and then compressed to extremely high pressure. This high pressure is necessary for the fuel to atomize correctly when injected into the engine cylinders, allowing uniform mixing with air and complete combustion .
