Advanced educational tool designed to provide a detailed view of a rotary injection pump’s internal mechanics. This cutaway model includes essential components such as the distributor plunger, transfer pump, centrifugal speed governor, and automatic advance variator. It features a vane transfer pump with pressure regulation capabilities, a centrifugal governor that adjusts fuel delivery based on engine RPM, and manual operation for hands-on learning. The model facilitates the study of hydraulic and mechanical delivery corrections, fuel pressure regulation, and the interaction of internal mechanisms for a comprehensive understanding of diesel fuel systems.
