Abstract
Asian countries hold a vast majority of the global two-wheeler population. Currently majority of these two wheelers are fueled by carburetors owing to their low cost and ease of maintenance. As these countries try to adopt emission norms similar to that of Euro 6 in a few years from now, they will be migrating to an injection system like port fuel injection (PFI), as it offers good control over emissions by using closed loop corrections, based on the exhaust lambda feedback. Stanadyne R&D has developed an innovative injection system that can be applied for such port fuel injection in two-wheelers. In this innovative design, the pump and injector are integrated into a single unit, making the system simple, compact and less expensive. The integrated injector uses a solenoid and spring arrangement, for pressurizing the fuel in a small chamber, and consumes less current. The pressurized fuel is then injected through orifice to produce spray in the intake port. This new concept injector components are modeled using a one dimensional (1-D) commercial code AMESim, and its hydraulic performance at various stages is simulated. The simulation results indicate that it is possible to meet the fuel injection pressure and flow requirements of the engine, using the new integrated design. The injector’s hydraulic characteristics are also measured by experiments and the model is validated appropriately. This paper discusses the results of hydraulic performance of this new concept injector, obtained through the simulation and experiments, and the feasibility of applying this injector on a two-wheeler engine.
