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.
Of the seven children born to Johann van Beethoven, only Ludwig, the second-born, and two younger brothers survived infancy. Caspar Anton Carl was born on 8 April 1774, and Nikolaus Johann, the youngest, was born on 2 October 1776. Beethoven's first music teacher was his father. He later had other local teachers: the court organist Gilles van den Eeden (d. 1782), Tobias Friedrich Pfeiffer (a family friend, who provided keyboard tuition), and Franz Rovantini (a relative, who instructed him in playing the violin and viola).
