One of the most important studies on using diesel fuel is the basic study of combustion chamber deposits in engines. These studies were conducted to investigate the effects of deposits on the engine and how deposits are formed in engines. Deposits in the combustion chamber are proven to be formed through three different stages: (1) the condensation of components in incomplete combustion process on the combustion chamber walls; (2) the interaction of unburned fuel droplets; (3) fuel flow (intake valve and nozzle). This paper aim is establishing a correlation between deposits formation on the wall surface when fuel droplets interact with heated wall surfaces and surface temperatures. The changes of heated surface temperature impacted on the interaction of fuel elements with the surface, the evaporation and the dryness or wetness of fuel. In addition, in this study, zones of temperature with greater or lesser deposition formation were also identified. This helps to clarify the complex fluctuations in the deposits combustion chamber in real diesel engines.
