Rated Injection Pressure: The rated injection pressure of the 4951501 fuel injection pump is typically in the range of 1000 - 1500 bar (100 - 150 MPa). This high pressure is necessary to atomize the diesel fuel effectively, ensuring that it burns evenly and completely within the engine cylinders. A proper injection pressure helps to improve combustion quality, reduce emissions, and enhance the overall performance of the NTA855 diesel engine.
Maximum Injection Pressure: The maximum injection pressure that the pump can generate is usually higher than the rated pressure, often reaching up to 1800 bar (180 MPa) or more for short periods. This additional pressure capacity allows the pump to handle different operating conditions, such as when the engine is under heavy load or during transient operations, ensuring reliable fuel injection under all circumstances.
