Goodwillbilanzierung nach US-GAAP combustion engines. At high power densities they must use light gas (hydrogen or helium) working fluids at relatively high pressure and high speed with difficult sealing problems and a relatively high maintenance requirement. The cooling system must have twice the capacity of that required for a di
