Abstract (en)
[origin: US6755076B1] The measuring device includes a first measuring chamber (8) into which fuel is injected, pressure sensor (62) and a temperature sensor (60) respectively measuring pressure and temperature in the first measuring chamber (8), devices enabling the measuring chamber to be at least partially drained, an electronic section controlling the system and analyzing information received from the sensors (46, 60, 62). The device also includes a second measuring chamber (20) arranged downstream from the first measuring chamber (8). Fuel which is drained from the first measuring chamber (8) is sent to said second chamber. The volume of the second measuring chamber (20) can vary according to the displacement of a piston (38). The displacement is measured with the aid of a displacement sensor (46).
