How deposit control additives deliver optimal diesel engine performance

Deposits on fuel injectors can cause significant losses in performance in diesel engines, especially in those more modern engines with high pressure common rail injection systems. Conventional nozzle tip deposits accumulate in and around the injector spray holes that direct fuel into the cylinder in preparation for combustion. These deposits affect the quality of the spray pattern, leading to less than optimal combustion efficiency. Internal diesel injector deposits, also known as IDID, are deposits that occur deeper inside the injector and affect the ability of moving parts to keep up with the demands of complex fuel injection sequences.

Higher quality diesel fuels contain deposit control additives that effectively remove both nozzle tip deposits and IDID, helping to return intended fuel delivery to the combustion chamber. This leads to engine performance improvements, such as restored power and fuel efficiency, reduced emissions, and overall better driveability.
