Questions and Answers:

Q: How fuel oil temperature affects the combustion process of a diesel engine?
A: Higher fuel oil temperature reduces viscosity which causes fuel oil spray finer atomisation.
This brings forward combustion earlier due to the lower viscosity of the fuel and finer atomisation.
Excessive heating can cause machinery parts, especially o-ring to degrade at a faster rate thus lowering expected life span of it, which may cause unforeseen leakages in due course.
Low fuel oil temperature > increases fuel viscosity and stickiness, thus causes fuel oil spray coarser atomisation.
In addition, the lower fuel oil temperature increases difficulty for ignition and proper combustion.
Therefore delayed ignition and incomplete combustion can lead to higher exhaust gas temp, shortened maintenance intervals due to excessive carbon produced, lowered Pmax.
