Title:
噴射システムの噴射量を測定するための方法、コンピュータプログラムおよび装置
Document Type and Number:
Japanese Patent JP4272886
Kind Code:
B2
Abstract:
For measuring the injection quantity (Vm) of injection systems ( 18 ), in particular in internal combustion engines, test fluid ( 22 ) is injected by the injection system ( 18 ) into a measurement chamber ( 12 ). To increase the precision and stability of the measurement, the volume of the measurement chamber ( 12 ) is kept constant during the injection. Moreover, a gas volume (Vg) is present in the measurement chamber ( 12 ). The injected volume (Vm) of test fluid ( 22 ) is ascertained from the pressure change (dP) in the measurement chamber ( 12 ) that occurs upon an injection of test fluid ( 22 ). The ascertainment of the injected volume (Vm) is done by means of the state equation for ideal gases.
