“…In this paper the waveform memory method was adopted to measure the B-H curve and others soft magnetic properties (shown in Table 3). The LabVIEW software by American NI Company was used to design virtual instrument and GUI, finally, using oscilloscope NI card NI5102 for data acquisition [15]. The testing results were shown in Fig.…”

A new near-net-shape technology (MIM Technology) has been first introduced to GDI injector processing expected to solve the problems of inefficiency, low machining accuracy, low material utilization rate and unstable performance that exist in traditional processes. In order to improve the comprehensive performance of GDI injector Fe-based Nano-crystalline, soft magnetic alloy material has been used, and some structures of the magnetic circuit parts have been optimized. The excellent machinability, physicochemical properties, materials applicable of the MIM technology has been analyzed by tracking test. The comprehensive performances of different GDI injector samples have been analyzed by simulation analysis and experimental validation. As a result, the samples which were processed by the MIM technology reduce the skin effect and eddy current loss by 9.8%, accelerate the starting current rise rate by 2.5% and shorten the dynamic response time by 14.2%. The dynamic injection quantity increases by about 2.5%, and the linear range of dynamic fuel injection quantity is expanded about 9.6%.

Small engines (<19kW) are used in many offroad applications, in both the domestic and industrial markets. The dominant driving force in these markets is cost; therefore the vast majority of these engines still use low cost carburettors to meter the fuel into the intake port. However all these engines are now facing increasingly strict emission targets and hence require new technologies to meet these new regulations, but any new technology must be extremely cost effective to be applicable.

“…Transient and multi-physics simulations of coupled electromagnetic have recently been widely used in mechanical and electronic products design and optimization. Watanabe et al [14] optimized the geometry of the magnetic circuit and developed a new injector based on dynamic electromagnetic field simulation, the dynamic response time had a great reduce compared with the conventional one. Bircher [18] and Motoyuki [19] performed multi-physics simulations of electromagnetic micro valves for automatic dispensing in chemistry applications.…”

“…Analytical studies were implemented to simulate the solenoid actuator for the electro-injector, depend on the required quantities of the diesel oil by M. Ricco et al [13], and a comprehensive structural modeling was carried out to secure and optimize the function ability of the electro-injector, in particular the interference fitting between different parts of this injector. To realize the optimum design for SIDI injector, a 2D static electromagnetic field simulation based on FEM was analyzed by Hideyuki Watanabe et al [14]. S.V.…”
