Like other brands from Volkswagen Group, Audi strives to become carbon neutral by 2050. Besides that, the company strives to do the Internal Combustion Engines with less CO2. On that occasion, Audi said all their V6 diesel engines, which develop up to 281 HP (210 kW) and which are manufactured after the second half of February this year, are compatible with HydroTreated Vegetable Oil (HVO).
“We optimize our existing internal combustion engines to be more economical and to create less show. One of the ways is to create a technical basis for the use of sustainable fuel,” said Head of Technical Development Oliver Hoffmann.
Audi claims that the HVO reduces CO2 emissions between 70 and 95 percent compared to the ordinary diesel. Fuel can be made of waste materials such as oil from the food industry and agricultural waste. These oils are converted into aliphatic hydrocarbons, which modifies oil properties to be usable in diesel engines.
“As the cetane rating of hvo is around 30 percent higher, the combustibility of the engines is enhanced. The Positive Noticeable When Cold Starting. We tested the effects on Various Components, The Performance, and Exhaust Emissions in Specific Validation Runs Before Granting Approval, “says Matthias Schober.
The Volkswagen Group also works on other alternative fuels such as e-fuel, currently used in racing Porsche and Lamborghini cars.
