| Research Abstract |
A gaseous fuel injection rate meter, which employs 1-dimensional pipe flow, was developed and it is shown that its measurement accuracy was improved to be the order of 1%. It is shown that several gas species and multi-stage injection are applicable to the injection rate meter. The development process of intermittent gaseous fuel jets was visualized using Mie scattering method, and their characteristics were revealed by use of the data of transient characteristics of injectors obtained by the injection rate meter.
