A Study on Emulsified Fuel Conditions and the Behavior of Diesel Engine Injection System based on Data Analysis

Abstract

The behavior of the injection system was determined through FFT and PSD analysis of the pressure dataof the common rail, and when the diesel fuel is mixed with water, the pressure data of the common rail,depending on the water content and engine rotation speed, represent a different frequency componentdistribution. Recently, a theory has been suggested that mixing diesel fuel with water controls engineoverheating, fuel efficiency, NOx, CO, etc., but if water content exceeds 10%, it can have a fatal adverseeffect on the engine's injection system. In the future, it is necessary to promote fault diagnosis and predictionstudies of diesel engines using FFT and PSD results from common rail pressure data.
