Title:
INJECTION MEASURING DEVICE AND VOLUME ELASTICITY MODULUS MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2014098355
Kind Code:
A
Abstract:

To reduce a measuring error caused by unevenness of fuel temperature inside a closed container.

An injection measuring device: calculates a volume elasticity modulus of fuel from pressure and temperature inside a closed container 1 filled therewith; measures a pressure change inside the closed container 1 when the fuel is injected thereinto through an injection nozzle 2; and calculates an injection amount or an injection rate of the fuel from the measured pressure change and volume elasticity modulus. The closed container 1 has a spherical internal space 11 where the fuel is filled therein. The injection nozzle 2 is fixed to the closed container 1 so that a tip (an injection port) of the injection nozzle 2 is arranged on an inner periphery of the spherical inner space 11. The temperature inside the fuel inside the closed container is equalized in a manner that agitates the fuel when the same is directly injected toward a center of the inner space 11 through the injection nozzle 2.
