When the hole gets to position 2, the forechamber is filled with pulverized wood from the top disk. At position 3, the hole is lined up with the pressure source from above and the access to the combustion chamber of the engine below. The wood is thus injected into the engine at high pressure. At this position, the forechamber is filled with air via the hole in the bottom disk. At this extremely high speed, the wood particles are broken down even further, and the following combustion is very thorough.
Wood is also a renewable source of fuel.
In corporations, both balance sheets and income statements are used. The balance sheet describes the long-range changes regarding assets and debts. The income statement shows short-range revenues and expenditures. Any balance sheet for roadbuilding projects is normally not produced. Consequently, the diminishing assets resulting through use of non-renewable natural resources remain hidden.
