Fuel Additive Systems â used in conjunction with a diesel catalyst, this type of DPF uses a fuel additive in order to aid the regeneration process. The additive enables regeneration to take place at a lower temperature of 400Â°C in conditions where regeneration would not normally be possible.
Similar to Mozart, Beethoven toured as a child prodigy. He arrived in Rotterdam in autumn 1781. Six years later, in 1787, Ludwig travelled to Vienna in Autumn where he first met Mozart, who Ludwig wanted to study under.
They are said to have met in Vienna in 1787, and Beethoven is said to have had a few lessons from Mozart. However, this is uncertain, as there is only one account of a meeting, and it is not contemporary. Beethoven knew much of Mozart's work.
