Abstract

This paper presents the effect of various high applied voltage levels on the responsiveness of fuel injectors on gasoline engines. During operation, the inductance in the injector changes at a certain value because of the change of magnetic permeability, which is the result of the needle lifting process, directly affects the curve of the current in the needle. On the other side, the amperage in the injector is hampered by another amperage produced by the phenomenon of self-inductance, leading the current in the injector increase slowly resulting in the needle lifting will be delayed. Normally, there are two ways to increase the response time that including the improvement of fuel injector shape and injection control method. But in this paper, to improve the response time without changing either the structure or the control method of the injector, the authors conduct research on increasing the operating voltage level in order to reduce the dead time of the needle. In particular, a mathematical description of the fuel injector amperage will be built based on two different inductance values, then some experiments are practiced to evaluate the response time of the fuel injector. Experimental results in the range of 12V to 30V indicated that the sensitivity of the injector was significantly improved.
