Why is it significant to monitor fuel oil viscosity?

Monitoring fuel oil viscosity is significant because it directly affects engine performance and efficiency. The viscosity of the fuel oil determines how well it can be atomized and burned in the combustion chamber. If the viscosity is too high, it can lead to incomplete combustion and increased deposit formation, resulting in reduced engine efficiency, potential damage, and more polluting emissions. Conversely, if the viscosity is too low, it can lead to excessive fuel flow and unstable combustion conditions.

Maintaining the appropriate viscosity ensures that the fuel is able to be effectively fed into the engine at optimal rates, which is crucial for achieving desired performance and efficiency levels. This is particularly important for modern engines that employ advanced technologies and require precise fuel characteristics to operate optimally. Monitoring viscosity helps to ensure smooth operation, reduces maintenance costs, and optimizes fuel consumption.
