Upload by Dipper

Technical Circular 0199-99-01218/6 EN defines which fuels are approved for all DEUTZ compact diesel engines, covering air-cooled and liquid-cooled models. It supersedes TR 0199-99-01218/5 and introduces updates such as new engine series and released fuels across specified sections. The circular sets conditions for use of fuels under emission regulations, including sulphur limits for engines with exhaust after-treatment systems and requirements tied to cetane number and lubricity. It also states documentation needs in warranty cases and outlines fuel standards by region (EN 590, ASTM, JIS, and others).

Technical Circular 0199-99-01218/6 EN This Circular supersedes: TR 0199-99-01218/5 Date: 07.11.2022 Author: Winkler, TE-TA / Rill, MS-II All DEUTZ diesel engines Fuels (Diesel engines) Alterations In comparison to TR 0199-99-01218/5 , the following changes have been made: Introduction ● New engine series – 5.2 Updates in the following chapters ● Released fuels 2 ● Diesel fuels – Non-road fuels and light heating oils 3 ● Jet fuels – Released engines 5 – Basic conditions to be observed 5 ● Paraffinic diesel fuels from synthesis (XTL fuels: GtL, BtL, PtL) or hydrotreatment ( HVO) 5 – Released engines 6 ● Biofuels – Released engines 9 ● Fuel specifications – Diesel fuel according to EN 590 18 – US diesel fuel according to ASTM D975b:2021 19 – Fuel with FAME content (B10) according to EN 16734 30 ● Editorial changes General This bulletin defines which fuels are approved for DEUTZ diesel engines (compact engines) . This Technical Bulletin applies for all air-cooled and liquid-cooled compact engines of the DEUTZ brand. For engines which are no longer in production, this bulletin applies accordingly. Only fuels specified in the respective national regulations and fuels for which the engines are certified with the corresponding valid emission regulation are to be used (for example, no fuel may be used in Europe if it only meets the limits of the US standard) . The certification measurements for compliance with the legal emission limit values are carried out with the test fuels specified in the laws. These correspond to the diesel fuels described in the following section, such as EN 590 , ASTM D975 or EN 15940 , for example. The operator is obliged to check the permission for the use of fuels according to the national regulations. © 11/2022 1/37 ID 002893-06 Technical Circular 0199-99-01218/6 EN Released fuels Due to the large quantity of variants and body of emissions legislation, a simple overview in a table is no longer possible. The customer must therefore observe the appropriate releases and restrictions in the respective chapters. Engines fitted with an exhaust gas after-treatment system such as a closed diesel particle filter ( DPF) , diesel oxidation catalytic converter ( DOC) or selective catalytic reduction system (SCR) may only be operated with sulphur-free diesel fuels (for example, in the EU maximum 10 mg/kg and in the USA maximum 15 mg/kg) . Otherwise compliance with the emission requirements and durability is not guaranteed. In a warranty case, the customer must prove that a nationally released fuel was used by providing a certificate from the fuel supplier. Diesel fuels All DEUTZ diesel engines for mobile work machinery are designed for a cetane number of at least 45. When using fuels with a low cetane number, a disturbing formation of white smoke and ignition stutter is to be expected under some circumstances. A cetane number of at least 40 is approved for the US market, which is why special engine versions were developed to avoid starting difficulties, extreme white smoke or increased hydrocarbon emissions. If the use of fuels with a very low cetane number is also known in advance in other countries, we recommend ordering the engines in EPA versions. In winter, it is generally recommended to use fuels with a higher cetane number than the minimum requirement of 40. Diesel fuels are released and can be used in accordance with the following specifications: | Fuel | | Specifications | | --- | --- | --- | | EN 590 | Biodiesel content max. 7 %(V/V) | Appendix 1 | | ASTM D975 Grade 1-D S15 | Biodiesel content max. 5 %(V/V) | Appendix 2 | | ASTM D975 Grade 2-D S15 | | | | JIS K 2204 | | Appendix 3 | | China diesel fuel according to GB 19147 | | Appendix 4 | | NATO F-54 | | on request | The EN 590 standard has the status of a national standard in the countries of the EU, e.g. DIN EN 590. The NATO fuel F-54 is equivalent to di

FAQs

What happens if a low cetane number fuel is used?

Using fuels with a low cetane number may cause white smoke formation and ignition stutter under some circumstances; winter use is generally recommended with a higher cetane number than the minimum requirement.
