Summary:

FuelNet is a generic computer code that predicts the flow transient processes in the fuel delivery systems. FuelNet uses the bond graph modeling technique to match the input and output boundary, and the modal approximation to simulate wave dynamics in the fuel lines. It also contains modules for fuel delivery components and engine operating conditions. This work is an application of FuelNet on the injector noise, the fuel rail fuel pressure pulsation, and the injector maldistribution at various operating conditions, such as the temperature, the fuel line material, the engine speed, and the injector pulse width. The effects of pulse dampers are also studied. Models for effective bulk modulus and modal number are developed to address the effect of fuel line materials and dimensions. The predicted liquid fuel pressure is applied to the acoustic model to estimate the injector noise, id est, the air pressure inside the passenger compartment
