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