Diesel generator injection assembly: Structure, working principle and performance analysis
First, Introduction
Diesel generator is one of the important power sources in modern energy system, and the fuel injection assembly as the core component of diesel generator, its performance directly affects the combustion efficiency, emission quality and operation stability of diesel engine. This paper will analyze and discuss the structure, working principle and performance of diesel generator injection assembly.
Second, the structure of the oil injection assembly
Diesel generator fuel injection assembly mainly includes fuel injection nozzle, fuel injector, fuel injection pump and other parts. Among them, the fuel injection nozzle is the key component of the fuel injection assembly, and its structure directly affects the atomization effect and combustion quality of the fuel. The injector is the key component to introduce high pressure fuel into the injector nozzle, and its performance directly affects the injection pressure and injection time of fuel. The fuel injection pump is the part responsible for driving the fuel injector, which adjusts the fuel supply according to the operating state of the engine and the load demand.
Third, the working principle
The working principle of the injection assembly of the diesel generator is mainly to drive the injector through the injection pump, introduce the high-pressure fuel into the injector nozzle, and then atomize the fuel into the cylinder through the special structure of the injector nozzle. In the injection process, the injection pressure, injection time and injection amount of fuel will affect the combustion process of the engine. Therefore, the performance of the fuel injection assembly has a crucial impact on the operating performance of the engine.
Fourth, Performance analysis
1. Injection pressure
Injection pressure is one of the important indexes to evaluate the performance of injection assembly. Appropriate injection pressure can ensure the atomization effect and injection distance of fuel, thereby improving the combustion efficiency and dynamic performance of the engine. At the same time, too high fuel injection pressure may lead to problems such as blockage and damage to the fuel injection nozzle, while too low fuel injection pressure may lead to poor fuel atomization effect and affect the combustion process of the engine.
2. Oil injection time
Injection time refers to the time from the piston to the top dead center to the complete injection of fuel. Reasonable injection time can ensure the full combustion of fuel and the full use of energy. Too late injection time may lead to insufficient combustion, smoke and other problems; Too early injection time may lead to too high temperature in the combustion chamber, affecting the life of the engine and the emission quality.
3. Fuel atomization effect
Fuel atomization effect is one of the important indexes to evaluate the performance of fuel injection assembly. Good fuel atomization effect can ensure that fuel and air are fully mixed, improve the combustion efficiency and power performance of the engine. At the same time, good fuel atomization effect can also reduce the emission pollution of the engine.
Fifth,The solenoid valve pump inside the generator mainly has the following functions:
1.Control of excitation current: The solenoid valve plays a key role in the work of the generator, which can control the excitation current of the generator. The magnetic field generated by the excitation system can generate current from the generator, and the solenoid valve can be adjusted as needed to ensure that the output voltage of the generator remains stable.
2.Control fluid flow: The solenoid valve can be used to control the flow of fuel, cooling water, lubricating oil and other media in the generator set. This control helps to realize the operation of the unit, such as starting and stopping, and ensure its smooth operation.
3.Protection of unit safety: The solenoid valve can also achieve the automatic protection function of the unit in some cases. For example, when the pressure of the lubricating oil is too high or the water temperature is too high, the solenoid valve will automatically cut off the start of the generator, thereby preventing damage to the unit and ensuring safety.
4.Adjustment and control: Solenoid valves can be used to achieve steady-state regulation and control of the generator set. For example, through the control of the solenoid valve, the speed and load of the turbine can be adjusted.
In some specific equipment such as Cummins generator set, the solenoid valve also plays the role of converting electromagnetic energy into mechanical energy, as an important part of the diesel generator oil circuit switch. The solenoid valve manages the diesel supply by controlling the on-off of the oil circuit.
Sixth,Conclusion
In summary, diesel generator fuel injection assembly is one of the core components of the engine, and its performance directly affects the combustion efficiency, emission quality and operation stability of the engine. Therefore, it is of great significance to deeply analyze and study the structure, working principle and performance of fuel injection assembly. In the future research, it is necessary to further explore the optimization of the design and manufacturing process of the fuel injection assembly, improve its performance and reliability, and provide better technical support for the energy-saving emission reduction and efficient operation of diesel generators.
