Cutaway model showcasing the high-pressure diesel common-rail fuel system. It features a radial piston pump (CP3) capable of handling pressures up to 1,800 bar, a high-pressure fuel rail with integrated rail-pressure sensor and pressure-control valve, and both solenoid-valve and piezo-inline injectors for comprehensive fuel metering and injection analysis. The model also includes a gear-type fuel pump for supplying fuel to injection modules. This educational tool provides detailed visibility of high-pressure components and their interactions, making it ideal for advanced technical training in diesel fuel systems.
