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.
Beethovenâs brother Caspar Carl died in 1815; per his will, Beethoven was appointed co-guardian of his nephew, Karl, with his sister-in-law, Johanna. Beethoven, rightly or not, felt his brotherâs widow unfit to raise a child and applied for, and won, sole custody. Beethovenâs fitness to raise his nephewâclearly a fulfillment of a long-frustrated wish in itselfâmay also be questioned; indeed, the difficulties between the two weighed heavily on the composerâs final years, culminating in Karlâs unsuccessful suicide attempt in 1826.
