Cutaway automotive training aid designed for study of LPG timed sequential injection systems used in petrol (gasoline) engines with multi-point electronic injection. All major components—including the LPG injectors, solenoid valve, reducer-vaporizer, sensors, and ECU—are sectioned to expose internal structures. This enables complete visual access to the internal design and working principles. The trainer includes an ECU, injector rail, LPG solenoid valve, reducer-vaporizer, pressure sensor, pressure stabilizer, switch commutator, manifold nozzles, coolant and gas temperature sensors, refueling valve, and level indicator, all mounted on a structured display panel.
