- Water Contamination: Diesel is a non-polar solvent, while water is a polar solvent. When water mixes with diesel, it forms an emulsion. This emulsion can cause problems in the fuel system, including clogging of fuel lines and injectors.
- Fuel System Corrosion: Water can lead to corrosion in the fuel system, including the fuel tank, fuel lines, and fuel injector. Over time, this corrosion can weaken the components, leading to leaks or complete failure.
- Loss of Lubricity: Diesel fuel also acts as a lubricant for fuel injection pumps and other moving parts in the generator. Water dilutes the lubricating properties of diesel, increasing friction and wear on critical components.
- Engine Damage: As the water-contaminated fuel burns in the engine, it can cause overheating and damage to the engine components, such as pistons, piston rings, and cylinder walls.
- Loss of Power: Water in diesel reduces the fuel's energy density, resulting in a decrease in power output from the generator.
- Difficult Starting: Mixing water with diesel can make starting the generator more difficult or impossible, especially in cold weather.
- Engine Stalling: Water in the fuel system can cause the engine to stall or run erratically.
- Smoke and Emissions: Incomplete combustion due to water contamination can produce excessive smoke and harmful emissions from the generator.
- Reduced Lifespan: Water contamination in the fuel system can significantly shorten the lifespan of the generator, requiring costly repairs or even replacements.
Therefore, it is essential to avoid mixing water with diesel fuel in a 15kVA generator to prevent these issues and ensure the proper functioning and longevity of the generator. If water contamination does occur, immediate steps should be taken to remove the water and any resulting damage.
