摘要

The assembly comprises a fuel cartridge (30), for driving fastening elements in an internal combustion engine hand tool (10), and at least an abacus relative to a fuel (38) of a plurality of curves representing the pressure of said fuel as a function of the temperature thereof and relating to a same plurality of filling rates of said fuel in the cartridge (30). The cartridge comprises a pressure sensor (70) adapted for measuring the fuel pressure in the cartridge (30). The fastening tool comprises, between a transferring device and the housing of the cartridge (30), a pressure sensor adapted for measuring the fuel pressure.
