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.
Beethoven was introduced in these years to several people who became important in his life. Franz Wegeler, a young medical student, introduced him to the von Breuning family (one of whose daughters Wegeler eventually married).
