Product Description
Distribution pump head manufacturer
The main function of the distribution pump is to provide high-pressure fuel for the diesel engine and distribute the fuel to each fuel injector in the order of the cylinder, ensuring the timing, quantity and pressure of fuel injection, thereby optimizing the performance and efficiency of the diesel engine.
The specific function of the distribution pump
Increase the oil pressure (constant pressure)
The distribution pump raises the fuel pressure to 10MPa to 20MPa, ensuring that the fuel can be injected into the cylinder at sufficient pressure to achieve complete combustion.
Control fuel injection time (timing)
The distribution pump starts and stops the fuel injection within the specified time according to the working condition of the diesel engine to ensure that the fuel is injected into the cylinder at the best time and improve the combustion efficiency.
Control fuel injection volume (quantitative)
The distribution pump adjusts the fuel injection volume to adapt to the different load and speed requirements of the diesel engine, thereby optimizing the power output and fuel economy of the diesel engine.
Simplify structure, improve efficiency
Compared with the traditional in-line plunger pump, the distribution pump can supply oil to multiple cylinders with only one pair of plunger pairs. It has a simpler structure, smaller volume and lighter weight, and is particularly suitable for small high-speed diesel engines.
Adapt to modern diesel engine technology
The distribution pump (such as the VE type distribution pump) further enhances the accuracy and response speed of fuel injection through precise control by electronic technology, meeting the requirements of modern diesel engines for low emissions and high performance.
Summary
The distribution pump, as the core component of the diesel engine fuel injection system, significantly improves the performance and efficiency of the diesel engine by controlling fuel injection at constant pressure, timing and quantity. Its characteristics of simple structure and small size have enabled it to be widely used in modern diesel engines.
