polttoaineruiskutusjärjestelmät

Polttoaineruis is a Finnish term that translates to "fuel rust" or "fuel corrosion." It refers to the degradation and damage that can occur to fuel systems, particularly in vehicles and machinery, due to the presence of water or other contaminants in the fuel. This phenomenon is most commonly associated with diesel fuel, but can also affect gasoline.

The primary cause of polttoaineruis is condensation. When fuel tanks are not completely full, or when there are significant temperature fluctuations, water vapor can condense on the inner surfaces of the tank and mix with the fuel. This water can then promote the growth of microorganisms within the fuel. These microbes consume fuel components, producing acidic byproducts. These acids, along with the water itself, contribute to the corrosion of metal components within the fuel system, such as fuel lines, injectors, and fuel pumps.

Symptoms of polttoaineruis can include reduced engine performance, stalling, difficulty starting, and increased exhaust emissions. In severe cases, the corrosion can lead to fuel leaks or complete failure of the fuel system.

Preventative measures include keeping fuel tanks as full as possible to minimize condensation, using fuel additives that can absorb water or prevent microbial growth, and regularly draining water separators if equipped. Ensuring fuel is sourced from reputable suppliers can also help reduce the risk of contamination.
