Fixed assets do not increase in value they sit on the books at purchase price, so any appreciation you decide has happened is not something you put on the books. There is a complicated way to do it dealing with both an asset account and an equity account, named something like unrealized asset appreciation. But doing that is a balance sheet type thing which has to be monitored closely since assets also drop in market value.
IMO a fixed asset account should be named for the fixed asset and the associated depreciation fixed asset account created as a sub account of the fixed asset.
ie
fixed assets
>> Truck
>> >> accum depreciation truck
>> computer
>> >> accum depreciation computer
etc etc
