Automotive fuels - Unleaded petrol containing more than 3,7 % (m/m) oxygen - Roadmap, test methods, and requirements for E10+ petrol

Automotive fuels - Unleaded petrol containing more than 3,7 % (m/m) oxygen - Roadmap, test methods, and requirements for E10+ petrol

This Technical Report presents an overview and time plan for test methods and requirements that could be expected for future unleaded petrol and petrol blends in Europe. This means unleaded petrol with an ethanol/oxygenates level higher than allowed in the Fuels Quality Directive, Annex I [4], which is petrol containing up to 3,7 % (m/m) of oxygen, more familiarly known as E10.
Specific issues that may apply for certain levels or types of oxygenates are highlighted where appropriate in the appropriate sections of this report. This report does not take into account all issues related to vehicles that are specially designed to run on a much wider range of oxygenate contents above E10+, for example up to E85.
The report covers fuels and vehicle concepts for both E10+-capable (without engine efficiency gains) and E10+-optimised (with engine efficiency gains).
NOTE 1   Following the large possible combinations and levels of oxygenates, the work focuses on unleaded petrol with a nominal ethanol content between 10 % (V/V) and 25 % (V/V). Once the ethanol is higher than approximately 20 % to 25 % (depending on the vehicle) more engine and vehicle measures would likely be needed.
NOTE 2   For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, respectively.
NOTE 3   Although EN 228 speaks about and defines "unleaded petrol", the wording "petrol" is used throughout this document for the sake of readability.

Goriva za motorna vozila - Neosvinčeni motorni bencin, ki vsebuje več kot 3,7 % (m/m) kisika - Smernice, preskusne metode in zahteve za bencin E10+

To tehnično poročilo predstavlja pregled in časovni načrt preskusnih metod in zahtev, ki jih je mogoče v prihodnosti pričakovati v povezavi z neosvinčenim motornim bencinom in mešanicami bencina v Evropi. To pomeni neosvinčeni motorni bencin z višjo ravnjo etanola/kisikovih spojin od dovoljene v skladu z Direktivo o kakovosti goriva, Priloga I [4], tj. motorni bencin z deležem kisika največ 3,7 % (m/m), bolje poznan kot E10. Posebna vprašanja, ki lahko zadevajo določene ravni ali vrste kisikovih spojin, so v zadevnih razdelkih tega poročila ustrezno označena. To poročilo ne upošteva vseh vprašanj, povezanih z vozili, ki so posebej oblikovana za delovanje z veliko širšim obsegom vsebnosti kisikovih spojin v motornem bencinu nad E10+, npr. do E85. To poročilo zajema koncepte goriv in vozil, ki uporabljajo E10+ (brez povečane učinkovitosti motorja) in so optimizirani za E10+ (s povečano učinkovitostjo motorja).

Automotive fuels - Determination of hydrocarbon group types and select hydrocarbon and oxygenate compounds - Gas chromatography with vacuum ultraviolet absorption spectroscopy (GC-VUV) method
SIST EN 18015:2024

This test method is a standard procedure for the determination of saturates, olefins, aromatics and oxygenates in unleaded petrol using gas chromatography and vacuum ultraviolet detection (GC-VUV).
Concentrations of compound classes and certain individual compounds are determined by mass fraction % (m/m) or volume fraction % (V/V). The concentration ranges for which the method is applicable are given in Table 1.
NOTE   For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction, respectively.
This test method has been tested for unleaded petrol according EN 228 [1]; Although specifically developed for the analysis of automotive motor gasoline including those that contain oxygenates this test method applies to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.
The method is found to be applicable to petrol containing other oxygenates than indicated in Table 1, such as isopropanol, iso-butanol, tert-butanol, n-propanol, acetone, tert-pentanol and di-isopropyl ether (DIPE), however precision has not been determined.
Table 1 —Application ranges
Compound or group   Units   Concentration range
Saturates   % (V/V)   21,48 to 80,87
Olefins   % (V/V)   0,22 to 41,90
Aromatics   % (V/V)   2,35 to 64,55
Benzene   % (V/V)   0,20 to 2,54
Toluene   % (V/V)   0,87 to 30,97
Ethylbenzene   % (V/V)   0,20 to 3,45
Xylenes   % (V/V)   0,49 to 18,59
Methanol   % (V/V)   0,07 to 15,30
Ethanol   % (V/V)   0,08 to 24,96
MTBE   % (V/V)   0,22 to 22,21
ETBE   % (V/V)   0,13 to 23,44
TAME   % (V/V)   0,24 to 21,96
TAEE   % (V/V)   0,24 to 8,60
Total oxygen content   % (m/m)   0,52 to 12,19
Individual hydrocarbon components are typically not baseline-separated by the procedure described in this test method. The coelutions are resolved at the detector using VUV absorbance spectra (Annex A) and deconvolution algorithms.
While this test method reports by mass fraction % (m/m) or volume fraction % (V/V) for several specific components that can be present in unleaded petrol, it does not attempt to speciate all possible components that can occur in unleaded petrol. In particular, this test method is not intended as a type of detailed hydrocarbon analysis (DHA).

Automotive fuels - LPG - Requirements and test methods
SIST EN 589:2024

This document specifies requirements and test methods for marketed and delivered automotive LPG (commonly known as low pressure gas or liquefied petroleum gas).
This document is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
NOTE   For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health arising through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. Naked flames, unprotected electrical equipment electrostatic hazards etc. are sources of ignition for LPG.
LPG in liquid form can cause cold burns to the skin. National health and safety regulations can apply.
LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.
CAUTION - One of the tests described in this document involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to.

Automotive fuels - Paraffinic diesel fuel and blends with FAME - Background to the parameters required and their respective limits and determination
SIST-TP CEN/TR 16389:2024

This document explains the requirements and test methods for paraffinic diesel fuel from synthesis or hydrotreatment. Synthesis refers to XTL processes where X refers to various feedstocks for example Gas (G), Biomass (B) or Coal (C) and TL stands for To-Liquid. Hydrotreatment of vegetable oils and animal fats yield Hydrotreated Vegetable Oil (HVO). Paraffinic diesel fuel can be blended with up to 7,0 % (V/V) fatty acid methyl ester (FAME). This document provides background information to the final text of EN 15940 [1] and gives guidance and explanations to the producers, blenders, marketers and users of paraffinic automotive diesel fuel.
Paraffinic diesel fuel is a high quality, clean burning fuel with virtually no sulfur and aromatics. Paraffinic diesel fuel can be used in diesel engines, also to reduce regulated emissions. In order to have the greatest possible emissions reduction, a specific calibration is needed. Some types of paraffinic diesel fuel, at present notably HVO, can also offer a meaningful contribution to the target of increased non-crude derived and/or renewable content in the transportation fuel pool.
For general diesel engine operation, durability and warranty, paraffinic automotive diesel fuel needs a validation step to confirm the compatibility of the fuel with the vehicle, which for some existing engines still needs to be done. The vehicle manufacturer needs to be consulted before use.
NOTE 1   This document is directly related to EN 15940 and will be updated once further publications take place.
NOTE 2   Paraffinic diesel fuel is also used as a blending component in automotive diesel fuel. In that case, composition and properties of the final blends are defined by relevant fuel specification standards.
NOTE 3   For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.

Liquid petroleum products - Determination of the ignition quality of diesel fuels - Fixed compression ratio engine method
SIST EN 16906:2023

This document specifies a test method for the determination of cetane numbers ("CN") of diesel fuels, using a standard single cylinder, four-stroke cycle, indirect injection engine. The cetane number provides a measure of the ignition characteristics of diesel fuels in compression ignition engines. The cetane number is determined at constant speed in a compression ignition test engine equipped with a swirl chamber.
The cetane number scale covers the range from 0 to 100, but typical testing is performed in the CN range from about 40 to about 75. The precision of this test method covers the CN range from 44 to about 66.
This document is applicable to distillate as well as paraffinic diesel fuels intended for use in diesel engines, including those containing up to a volume fraction of 10 % fatty-acid methyl esters (FAME), ignition-improvers or other diesel fuel additives.
When this engine test procedure is used for other fuels such as synthetics and vegetable oils, samples with fuel properties that interfere with the gravity-based pre-supply pressure to the fuel pump e.g. due to high viscosity can only be used to a limited extent. Precision data for such fuels are not available at this stage.
NOTE   The test method is also suitable for determining cetane numbers outside the range of the scope; however, the precision statement only applies for fuels in the specified range.
