Diesel Generator Tech

Diesel generator sets are designed to provide electricity during power outages or in places without connection to a power grid. They are renowned for their durability, high efficiency, reliability and longevity. As an important part of the power supply system, the stability and safety of diesel generators’ electrical system is directly related to the continuity and reliability of power transmission. In this article, we’ll share several tips on how to maintain the generator’s electrical system. The electrical system of diesel generator set serves as the bridge to connect with mechanical energy and electric energy, and it is the key to ensure the stable transmission of power. However, the electrical system may encounter various problems over time, such as aging, wear and tear and contamination, which will affect its performance and stability. Therefore, the maintenance of diesel generator’s electrical system is essential. The electrical system of diesel generator set is mainly composed...

The working principle of the cooling system of a diesel generator set is heat transfer. Heat always moves from hot objects to cold objects. There are three ways of heat transfer: conduction, convection, and radiation. Conduction refers to the heat transfer between two solid objects. For example, heat is transferred from the valve stem to the valve guide. Due to both objects being solid, heat is transferred from the hot air rod to the cold valve guide through conduction. For example, heat is transferred from the air duct to the cylinder head through conduction. Heat can be transferred through convection. Convection is the heat transfer that occurs through the circulation of heat in a liquid or gas. Through convection, the heat from the hot cylinder body is transferred to the coolant, and when the hot radiator components transfer heat to the surrounding cold air, convection also occurs. Radiation is a way of heat transfer. Radiation is the heat transfer that occurs by converting thermal...

Before purchasing a backup power generator, you need to consider a number of factors, such as your power requirements and fuel source. A right diesel standby generator can provide you with reliable electricity and bring you peace if mind during power outages. However, many people often make the following 5 common mistakes when buying a backup diesel generator. To make sure you buy a right generator for your home or business, you need to avoid these mistakes. Overestimate or underestimate power requirements It’s important to pick a correct size diesel standby generator that can provide the necessary amount of power to run all of the equipment without overloading the generator. If you overestimate or underestimate the power need and select a wrong sized diesel generator set, the generator may be damaged and your business operations may also be affected. Oversizing your generator can lead to inefficient operation and increased fuel consumption, while undersizing may result in power outa...

This article continues to introduce the working principle and structure of the hole type fuel injector for diesel generator users. High pressure fuel enters the annular groove at the upper end of the needle valve body through the oil passage in the filter element and injector body from the inlet pipe joint. This groove is connected to the annular space at the lower part of the needle valve body through two inclined holes. The high-pressure diesel flowing through the lower cavity exerts an upward axial thrust on the conical surface of the needle valve. When this force overcomes the frictional force between the pressure regulating spring and the needle valve body (which is very small), the needle valve moves upward and opens the injection hole [as shown in Figure 5-2 (b)]. Therefore, high-pressure fuel is sprayed into the combustion chamber from the injection hole at the lower end of the needle valve body. The lift of the needle valve is limited by the lower end face of the injector bod...

The fuel of a diesel engine is injected into the cylinder near the end of the compression process. The function of the fuel injector in a diesel generator set is to atomize the fuel into fine particles and distribute them appropriately in the combustion chamber, forming a good combustible mixture. Therefore, the basic requirements for the fuel injector are: a certain injection pressure, a certain range, a certain spray cone angle, good spray, quick fuel stop at the end of fuel injection, and no fuel dripping. The hole type fuel injector of diesel generator set is mainly used in direct injection diesel engines. Due to the number of spray holes and small aperture, it can spray several spray columns with small cone angles and longer range. The general number of fuel injection holes is 2-8, with a diameter of 0.15-0.50mm. The number and direction of spray holes depend on the requirements of various combustion chambers for atomization quality and the arrangement of injectors in the combust...

  In modern society,   diesel generators   have been widely used in different fields, such as industrial, commercial, medical, communication and emergency relief.
