According to MAN Engines, all off-road engines from the current product portfolio can be operated with regenerative diesel – also known as HVO (hydrogenated vegetable oil) – in accordance with the EN15940 standard in Europe or the US specification ASTM D975.
Off Road Engines
The approval applies to all off-road engines for the current EU Stage V and EPA Tier 4 emission standards and below. Marine engines for regenerative diesel have already been approved. Customers can use it to replace – or mix – conventional diesel fuel and use MAN engines with so-called green or renewable diesel. This is obtained on the basis of waste and residues of animal and plant origin, cellulosic biomass materials such as crop residues, among others. “Sustainability is very important to us at MAN Engines. That’s why we’ve approved almost our entire engine portfolio for the use of regenerative diesel,” says Mikael Lindner, head of MAN Engines.
No Performance Losses
For Werner Kübler, head of engineering at MAN Engines, there are also other clear advantages: “There are no performance losses or disadvantages with regard to the service and maintenance intervals of our MAN engines, and the AGN also works without any problems. In addition, due to its similar chemical composition to fossil diesel, the use of HVO does not require any modification to existing vehicles or refueling station infrastructure. This can be refueled pure, i.e. 100% as HVO100, or with an admixture – at any mixing ratio – of conventional diesel fuel. At the end of February 2023, the German government decided to include DIN EN 15940 in the 10th Ordinance on the Implementation of the Federal Immission Control Act (BImSchV). This means that these synthetic fuels can be sold in their pure form at public filling stations. In addition to the use of regenerative fuel/HVO, the aforementioned MAN off-road engines are also approved for R33 fuel, which contains 33 percent of regenerative components.
