The standard Lanz hot-bulb engine with a displacement of 10.3 L was used, it has a thermosiphon cooler. Compared to the predecessor series HR 6 and HR 7, the engine now has a better speed governor, the rated engine speed was increased from 540 min−1 to 630 min−1.[1] Many sorts of diesel oil can be used as fuel.[5] The D 9506 has an electrical system.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
