Abstract
Diesel fuel quality can be considered from many different points of view. Fuel producers, fuel consumers, and ecologists have their own ideas. In this paper, a sensor of diesel fuel quality type, and fuel condition that is oriented to the fuel’s consumers, is presented. The fuel quality types include premium, standard, and full bio-diesel classes. The fuel conditions include fuel fit for use and fuel degraded classes. The classes of fuel are connected with characteristics of engine operation. The presented sensor uses signal processing of an optoelectronic device monitoring fuel samples that are locally heated to the first step of boiling. Compared to previous works which consider diesel fuel quality sensing with disposable optrodes which use a more complex construction, the sensor now consists only of a capillary probe and advanced signal processing. The signal processing addresses automatic conversion of the data series to form a data pattern, estimates the measurement uncertainty, eliminates outlier data, and determines the fuel quality with an intelligent artificial neural network classifier. The sensor allows the quality classification of different unknown diesel fuel samples in less than a few minutes with the measurement costs of a single disposable capillary probe and two plugs.
Highlights
With the use of diesel fuel come considerations of its quality, cost, and type. All these factors are directly connected with the composition of the diesel fuel which consists of the fuel base, fuel improvers, and impurities
Discussion from a different origin that samples used for artificial neuralThe network (ANN) learning
The results show the proper classification are from a different origin that samples used for ANN learning
Summary
With the use of diesel fuel come considerations of its quality, cost, and type. All these factors are directly connected with the composition of the diesel fuel which consists of the fuel base, fuel improvers, and impurities. The type of diesel fuel may be described by the fuel base origin or the dominant technological process. Standard fuel base components may include petroleum diesel (petro-diesel), synthetic diesel (syn-diesel), fatty-acid methyl esters (FAME), and hydrogenated oils (HVO). Syn-diesel can be produced from any carbonaceous material, by gasification, purification, and conversion processes [2]. FAME is obtained from vegetable oil or animal fats with the use of transesterification reaction. HVO is a composition of alkanes obtained in the refining and hydrogenation process of vegetable oil and animal fats. Non-esterified vegetable oil was considered as fuel a bio-component [3]
