Abstract
The invention relates to a device that includes: a first chamber () for measuring a constant volume, and in which the fuel is injected; pressure () and temperature () sensors associated with said first chamber (); and a second measuring chamber () located downstream from the first, into which the fuel drained from the first chamber is sent. The volume of the second chamber () varies according to the movement of a piston (), the movement of which is measured by means of a sensor (). One or more additional measuring chambers () of variable volumes are connected in parallel with the second chamber () and also receive the fuel drained from the first chamber (), the volumes received in said different chambers being added up to obtain the total volume supplied for a single injection step. The device can be used for high injection rates.
