- Approval for trucks with heavy-duty OM 470, OM 471 engines as well as medium-duty OM 936 and OM 934 variants
- Use of HVO validated by extensive testing; maintenance intervals unchanged
- The HVO raw material is sourced from controlled and certified cultivation facilities and as such does not compete with foodstuff production
- Clean, economical and powerful: engines from Mercedes-Benz
With immediate effect Mercedes-Benz Trucks is granting approval for the use of the alternative fuel known as Hydrotreated Vegetable Oil (HVO). HVO is a biodiesel fuel which comes from waste materials such as waste fat, used cooking oil and also oil from crop plants. The HVO raw material is sourced from controlled and certified cultivation facilities and as such does not compete with foodstuff production. The approval from February 2016 relates to the in-line six-cylinder engine variants of the Mercedes-Benz OM 470, OM 471 (first generation) and OM 936 as well as the in-line four-cylinder variants of the OM 934 meeting the Euro VI emissions standard. The engines are designed as standard to make use of the new HVO fuel.
OM 470, OM 471, OM 936 and OM 934
Trucks from Mercedes-Benz fitted with engines from the OM 470, OM 471, OM 936 and OM 934 series meeting the Euro VI emissions standard may be operated with HVO from February 2016. This decision applies to all engine variants whatever their output category. HVO is a second-generation biodiesel fuel. This “green” diesel has been produced on an industrial scale since 2007.
HVO is sulphur-free and contains no aromatics, while no ash is produced during the combustion process. The fuel can be used either in its pure form as an alternative to conventional diesel fuel or as an admixture in order to improve overall environmental performance. Use of unblended HVO above all leads to dramatic improvements in CO2 performance.
Use of HVO validated by extensive testing; maintenance intervals unchanged
Mercedes-Benz Trucks has established the acceptability of the alternative fuel for use in its engines by means of comprehensive testing. Since the characteristics of HVO mean that it is absolutely comparable to conventionally produced petroleum-based diesel fuel, no modifications to the engines or their peripherals are necessary. The injection process, fuel lines and seals remain unchanged.
The same is also true of the intervals for oil changes and for cleaning the particulate filter, while there is also no restriction in terms of warranty and goodwill policy. Engine performance and torque data also remain the same when HVO is used.
The approval applies to all fuels that comply with the prEN 15940 standard.
Clean, economical and powerful: engines from Mercedes-Benz
The ultra-modern in-line six-cylinder engines of the Mercedes-Benz OM 470, OM 471 and OM 936 series are as clean and economical as they are powerful.
The light-duty variant, the four-cylinder OM 934 with a displacement of 5.1 l, covers the output range from 115 kW (156 hp) to 170 kW (231 hp) to optimum effect. The six-cylinder common-rail OM 936 engine covers a higher output range, generating from 175 kW (238 hp) to 220 kW (299 hp) and featuring a displacement of 7.7 l litres.
The heavy-duty Mercedes-Benz OM 470 unit produces between 240 kW (326 hp) and 315 kW (428 hp) from a displacement of 10.7 litres.
