The automatic diesel generator set runs on diesel fuel, and the quality of this fuel plays a critical role in the performance and reliability of the unit. Poor-quality diesel can lead to reduced power output, frequent breakdowns, and long-term damage to engine components. High-quality diesel ensures efficient combustion, better performance, and longer service life for the generator. On the other hand, using low-quality or contaminated diesel can cause serious issues that affect both the engine and the overall system. Let’s take a closer look at what happens when inferior diesel is used in a fully automatic generator set. 1. High sulfur content Diesel with high sulfur levels can degrade the quality of the lubricating oil, reducing its effectiveness and leading to poor engine lubrication. This can result in increased wear and tear on internal engine parts, ultimately affecting the performance and longevity of the generator. 2. Low calorific value If the diesel fuel has a lower energy content than specified, it will not burn efficiently. This leads to higher fuel consumption and an inability to reach the rated power output. As a result, the generator's performance drops, and it may fail to meet the required load demands. 3. High carbon content Excessive carbon buildup from incomplete combustion can clog engine components, reduce efficiency, and increase the temperature inside the combustion chamber. This can cause premature wear on piston rings and cylinder liners, leading to costly repairs. 4. Moisture content Water in diesel fuel can damage precision components such as fuel pumps and injectors. It can also cause corrosion, which may lead to malfunctions and decreased performance over time. 5. Impurities Contaminants like dirt, sand, or other foreign particles can damage fuel injectors, causing them to wear out faster. This can lead to uneven fuel distribution, poor combustion, and potential engine failure. 6. Clogged diesel filters Poor-quality diesel often causes filters to become clogged more quickly, reducing fuel flow and decreasing the generator's power output. This also shortens the interval between filter replacements, increasing maintenance costs. When selecting diesel fuel, always check its appearance. Quality diesel should be clear and light yellow in color. If the fuel appears cloudy, dark, or discolored, it may contain impurities or water. The density of good diesel is typically around 0.85. If the density is too high, it could mean there is water in the fuel, which can cause incomplete combustion, black smoke, and excessive carbon buildup. If the density is too low, it may lead to knocking, increased mechanical stress, and even fire hazards. To ensure optimal performance and avoid unnecessary failures, it's recommended to purchase diesel from reputable gas stations. Avoid buying cheap or unknown-source diesel, as it can significantly reduce the lifespan of your generator set. Choosing the right fuel is one of the simplest yet most effective ways to maintain the reliability of your fully automatic generator.
