Abstract

The effect of the electrical pulse width and the fuel temperature on dynamic flow and static flow rate of a gasoline fuel injector has been numerically and experimentally investigated. In numerical analysis, the physical domain covers the region from upstream of the valve seat to the injector exit. The three-dimensional unsteady Navier-Stokes equations in a curvilinear coordinate system are solved. Due to the needle movement in fuel injection, the physical domain is considered as a function of time. In the experimental study, the test stand consisting of a hydraulic system and an electrical system was designed to meet the requirements of Society of Automotive Engineers. The pulse width of 0.97–7.5 ms and the temperature of 20–100°C were used to study the pintle injector performance. Predicted dynamic flow and static flow rates show higher values at a temperature of 80°C, which are consistent with the test results.
