Definitions
- the invention relates to a method for determining the tendency to form soot by means of a gas chromatographic component analysis of hydrocarbon types and oxygenates of a mixture of substances.
- the topic of soot particle formation in fuels is very crucial these days, as the emissions and soot particle formation from motor vehicles should be continually reduced. This is particularly due to the tightening of the guidelines in connection with the EU 7 reform.
- the new guidelines must be met for motor vehicles and fuels and a range of different fuels must be tested.
- the inventory effectiveness must be checked, for example for City Fuels.
- the YSI Yield Sooting Index
- the YSI represents a good basis for describing the tendency to soot formation.
- the YSI is referred to in German as the soot formation tendency index. This index is currently complicated to determine. It is then possible to determine the soot formation tendency index by means of an individual component analysis of a fuel.
- EP 1 953 545 A1 discloses a method for the quantitative analysis of a mixture of molecular compounds by two-dimensional gas chromatography, in which a two-dimensional chromatogram (CHR) is generated from a chromatographic signal (SB) and chromatographic peaks are selected on the polygon aid.
- CHR two-dimensional chromatogram
- SB chromatographic signal
- the method includes the following steps for at least one polygon: fitting a polygon by identifying portions of the chromatographic signal contained in the polygon, with the following further steps: (a) determining start times, end times and maximum chromatographic peaks, present on the portions, (b) The polygon is adjusted by moving intersections between the polygon and the sections as a function of the start times, the end times and the maximum chromatographic peaks, (c) An amount of at least one molecular compound is determined by the area of the adjusted polygon is calculated.
- Document WO 1997/01142 A1 describes a method for predicting physical, perceptual, performance or chemical properties of a complex hydrocarbon mixture, comprising: (a) selecting at least one property of the hydrocarbon mixture, (b) selecting reference samples, wherein the Reference samples contain characteristic types of compounds present in the complex hydrocarbon mixture and which have known values of the property or properties selected in step (a), (c) creating a sample set by the steps: (1) injecting each reference sample into a gas chromatograph equipped with is connected to a mass spectrometer, which causes at least a partial separation of the hydrocarbon mixture into chemical components. (2) Introducing the chemical components of each reference sample into the mass spectrometer under dynamic flow conditions. (3) Obtain a series of time-resolved mass chromatograms for each reference sample.
- step (f) multiplying the matrix from step (e) by the coefficients from step c (10) to produce a predicted value of the property or properties.
- the invention is based on the object of developing a simplified method for determining a soot formation tendency index for a mixture of substances, which consists of a large number of individual components that differ in terms of material and percentage volume, in particular hydrocarbon types and oxygenates, whereby the method result should be suitable , to incorporate the soot formation tendency of mixtures of substances to be compared into the standardization in the form of a soot formation tendency index assigned to the substance mixtures.
- the starting point of the method according to the invention is the ISO 22854:2016 standard with the title “Liquid mineral oil products - Determination of hydrocarbon types and oxygenates in motor vehicle gasoline and in ethanol (E85) - Multidimensional gas chromatography method”.
- a reformulyzer analysis according to ISO 22854 is available for most fuels used today. This means that in most cases there is no individual component analysis, but rather a reformulyzer analysis according to the ISO 22854 standard.
- Gas chromatography is carried out according to ISO 22854. The result is then presented as a so-called Reformulyzer in a so-called Reformulyzer output.
- the individual components are divided into functional supergroups and Reformulyzer groups, whereby the Reformulyzer analysis contains the Reformulyzer groups i, which are differentiated according to the number of carbon atoms.
- the Reformulyzer groups i, divided according to the number of carbon atoms, are also referred to as Reformulyzer subgroups.
- the YSh of the respective Reformulyzer subgroup i will be taken from a database available for this purpose, which the applicant has created by evaluating the individual components belonging to the respective Reformulyzer subgroups i.
- the database comprises the individual components belonging to a Reformulyzer subgroup i with the respective YSh of the respective individual components, the YSh for the respective Reformulyzer subgroup i being determined within the database according to the invention.
- the method has preferred embodiment variants.
- the Reformulyzer subgroups i for example C7 and C8, can form a single Reformulyzer group.
- Subgroup can be combined. This means that less data has to be added up in the last step of the process, summing up.
- Reformulyzer subgroups i that are close to one another and whose values are less than five volume percent apart are combined into several functional Reformulyzer supergroups.
- Reformulyzer subgroups i can be combined across several functional Reformulyzer supergroups, for example C7 and C8 to C(7+8) of the Reformulyzer supergroups to form a Reformulyzer subgroup i. This means that less data has to be added up in the last step of the process, summing up.
- the first embodiment variant can be advantageously combined with at least one of the second to fourth embodiment variants.
- the advantages of the method are that the costs for determining the overall soot formation tendency index YSItotal are reduced because there are no
- a standard determination of the overall soot formation tendency index YSItotal also advantageously leads to a standard and standardizable statement about the soot formation tendency for each fuel F or additive B. That is, using the overall soot formation tendency index YSItotal can A comparison of the overall soot formation tendency indices YSItotal of different fuels F and additives B can advantageously take place and be standardized in a standard.
- the invention provides that all fuels for which the tendency to soot formation must be predicted can be examined and evaluated, in particular standardized, using this method.
- the method can advantageously be used when developing new fuels F or additives B as well as when checking existing fuels.
- the overall soot formation tendency index YSItotal When operating the vehicles, it is possible according to the invention for the overall soot formation tendency index YSItotal to be transmitted either automatically (for example wirelessly) or manually to a receiving unit, in particular a control device with the receiving unit of a vehicle. If such a value is present in the engine control unit, the soot formation tendency index YSItotal can be used for a more precise determination of the control of the operating parameters of the internal combustion engine and/or the exhaust system.
- the soot formation tendency index YSItotal can also be displayed to the user via the HMI, so that the user has standardized information about whether he is using a fuel F or an additive B that tends to produce a high level of soot formation or a low level of soot formation.
