VW still counts on diesel engines, the new TDI can burn paraffin fuels

In addition to higher production of electric cars, VW also wants to contribute to reducing emissions by approving greener fuels for new generations of four-cylinder diesel engines.

In a recent press release, Volkswagen officially announced that the latest generation of four-cylinder diesel engines has been approved for the use of so-called paraffin fuels, a newly developed greener diesel that contains biodegradable components.

Specifically, we are talking about four-cylinder TDI engines manufactured since the end of June (week 25) this year, which have been approved for the use of paraffin diesel in accordance with European standard EN 15940. The new fuel should save about 75 to 90 percent CO emissions compared to conventional diesel.2.

These paraffin fuels are produced from biological residual and waste materials, such as hydrogenated vegetable oil (HVO). These substances can then be added to conventional diesel or can be used separately as 100% fuel.

Various vegetable oils can be used for the production of HVO, such as rapeseed oil, but the maximum environmental benefit is usually achieved by processing biological residual and waste substances, such as cooking oil, sawdust, etc.

Fuels such as HVO are already available on the market and VW expects their share of the road energy market in Europe to increase to around 20 to 30 percent over the next ten years. Paraffin fuels are already appearing on the market, for example under the name CARE diesel, NEXTBTL or HVO.

However, paraffin fuels can also be part of conventional diesel that meets the parameters of EN 590, such as Diesel R33, V-Power Diesel, OMV MaxMotion or Aral Ultimate Diesel. It should then be possible to refuel these fuels in older diesel engines as well.
